Ouigo
–
Ouigo is a French low-cost train service based at Marne-la-Vallée offering services to the north, the north-west and the south-east of France. It is a subsidiary of the French national rail company SNCF, the service was announced in by the head of SNCF, Guillaume Pepy on 19 February 2013, and it launched services on 2 April that year. Unlike Europes relatively liberalized airline market, high speed railways in France are a monopoly owned and operated by the government. However ongoing talks about high speed railways liberalization, targeted for as early as December 2019 and they must be purchased at least 4 hours in advance of the journey. Four days before travel, they receive an e-mail of the ticket which they may print out at home. Since October 2013, customers can book tickets via the non-affiliated booking agent Captaine Train. Ouigo uses modified double-decker TGV Duplex trains, which are single 2nd class made up of either 2x2 or 3x1 abreast and this leads to the train carrying up 1200 passengers, which is 20% more passengers than regular TGV Duplex trains. Similar to some low cost airlines, whilst a piece of luggage is allowed free of charge. The trains carry fewer members of staff, which like the low-cost carriers are tasked as well to do basic maintenance of the train as well as serving passengers. The company sweats its assets by using the trains for up to 13 hours a day, like some low-cost air carriers, the only way customers can contact the company is via their website. There is no customer service number or e-mail address. Ouigo offers trains stopping at a number of stations, unlike standard TGV services, and in order to offer lower fares, the company uses non-major stations for main destinations such as Paris or Lyon. In order to significantly lower prices than on standard TGV trains, Ouigo trains lack a buffet car, have a greater number of more tightly packed seats. Adult fares can vary from as little as €10 to a maximum of €115 per journey depending on the time of the journey, supplementary fees are as follows, Children that are 11 or under, a flat fee of €5 is charged no matter the journey. Baggage is €5 if booked at the time of booking, €10 prior to travelling on-line, pets can be taken on board, however provided that they are under six kilos and they are in the carry case as part of the hand luggage they travel free. If not, they are charged a fee of €40 per animal, seats next to plug sockets can be reserved for a supplementary fee of €2 per person. So far reactions to the service have been mixed, in the few months between announcement to the commencing of journeys, Ouigo has sold 200,000 tickets and its website has been visited by over 2 million times. In the first few months, Ouigo sent passengers a short questionnaire after each trip, the survey also reported that about 90% of passengers would recommend Ouigo to a friend or family member

LGV Bretagne-Pays de la Loire
–
The LGV Bretagne-Pays de la Loire is a high-speed rail line under construction, running between Connerré and Cesson-Sévigné, in France. Scheduled to be complete in late 2017, it will be serviced by TGV trains operated by SNCF, the total cost is put at €3. 4bn, with funding agreed on 29 July 2008 between the various bodies involved. The French government will contribute €990m, equal to contributions from local government, the remaining €1. 02bn comes from RFF. On 18 January 2011, it was announced that Eiffage had won, Eiffage, the funding agreement was signed on 12 July 2011. At this time, preliminary studies were scheduled to take place between May 2011 and July 2012, with construction starting during the autumn of 2012, the line begins as an extension of the LGV Atlantique western branch near Connerré. After a connection north of Le Mans, the LGV dips towards the southwest with a connection to the regular Le Mans-Angers line near Sablé-sur-Sarthe, the connection, at a length of 32 km, from Sablé-sur-Sarthe will slightly speed up the journey to Nantes. The line then rises to pass north of Laval and re-join the regular ligne at Cesson-Sévigné, the total length of the route is roughly 214 km of which 182 km will be high speed. The journey time for Paris to Brest and Quimper would have been 3 hours

High-speed rail in France
–
The first French high-speed rail line opened in 1981, between Pariss and Lyons suburbs. It was at time the only high-speed rail line in Europe. As of December 2014, the French high-speed rail network comprises 2,037 km of Lignes à grande vitesse, in 1976, the government agreed to fund the first line. The LGV opened to the public between Paris and Lyon on 27 September 1981, high-speed lines based on LGV technology connecting with the French network have been built in Belgium, the Netherlands and the United Kingdom. The newest high-speed lines allow speeds of 320 km/h in normal operation, originally LGVs were defined as lines permitting speeds greater than 200 km/h, revised to 250 km/h. Like most high-speed trains in Europe, TGVs also run on tracks, at the normal maximum speed for those lines. TGV track construction has a few key differences from normal railway lines, the radii of curves are larger so that trains can traverse them at higher speeds without increasing the centripetal acceleration felt by passengers. The radii of LGV curves have historically been greater than 4 km, LGVs can incorporate steeper gradients than normal. This facilitates planning and reduces their cost of construction, the high power/weight and adhesive weight/total weight ratios of TGVs allow them to climb much steeper grades than conventional trains. The considerable momentum at high speeds also helps to climb these slopes very quickly without greatly increasing energy consumption, the Paris-Sud-Est LGV has grades of up to 3. 5%. On a high-speed line it is possible to have greater superelevation, since all trains are travelling at the same speed, curve radii in high-speed lines have to be large, but increasing the superelevation allows for tighter curves while supporting the same train speed. Allowance for tighter curves can reduce costs by reducing the number and/or length of tunnels or viaducts. Track alignment is more precise than on railway lines, and ballast is in a deeper-than-normal profile, resulting in increased load-bearing capacity. Heavy rail is used and the rails are more upright, with an inclination of 1 in 40 as opposed to 1 in 20 on normal lines. Use of continuously welded rails in place of shorter, jointed rails yields a comfortable ride at high speed, the points/switches are different from those on the lignes classiques. Every LGV set of points incorporates a swingnose crossing, which eliminates the gap in support that causes shock. Eliminating these gaps makes the passage of a TGV over LGV switches imperceptible to passengers, reduces stresses on wheels and track, the diameter of tunnels is greater than normally required by the size of the trains, especially at entrances. This limits the effects of air pressure changes and noise pollution such as tunnel boom, LGVs are reserved primarily for TGVs

High-speed rail in Belgium
–
Belgiums high-speed rail network provides mostly international connections from Brussels to France, Germany and The Netherlands. Four high-speed train services operate in Belgium, Thalys, Eurostar, InterCityExpress. All operators stop in Brussels-South railway station, Belgiums largest train station, some services also stop in Liège and Antwerp. Eurostar connects Brussels to London St Pancras, the German ICE operates between Brussels-South, Liège-Guillemins railway station and Frankfurt Hauptbahnhof via Köln. There are three high-speed lines in Belgium which support 300 km/h operation, and one that supports speeds up to 260 km/h, all are electrified at 25 kV AC,50 Hz, unlike most of the rest of the network which uses 3 kV DC. HSL1 connects Brussels with the French border,88 km long, it began service on 14 December 1997. The line has appreciably shortened rail journeys, the journey from Paris to Brussels now taking 1,22. In combination with the LGV Nord, it has also impacted international journeys to France and London, ensuring high-speed through-running by Eurostar, TGV, Thalys PBA, the total construction cost was €1.42 billion. HSL2 runs between Leuven and Ans.95 km long it began service on 15 December 2002, combined with HSL3 to the German border, the combined eastward high speed lines have greatly accelerated journeys between Brussels, Paris and Germany. HSL2 is used by Thalys and ICE trains as well as fast internal InterCity services, HSL3 connects Liège to the German border. 56 km long, it was completed on 15 December 2007, HSL3 is used by international Thalys and ICE trains only, as opposed to HSL2 which is also used for fast internal InterCity services. HSL4 connects Antwerp north to the Dutch border where it meets the HSL-Zuid and it is 87 km long, comprising 40 km dedicated high speed tracks and 57 km modernised lines. Mostly completed in 2007, the opening of the line was delayed till December 2009 due to problems with signalling, HSL4 is used by Thalys trains and fast internal InterCity and NS Hispeed train service is planned for 2012. Between Brussels and Antwerp, trains travel at 160 km/h on the existing line. At the E19/A12 motorway junction, trains leave the line to run on new dedicated high-speed tracks to the Dutch border at 300 km/h. 25N, which is part of the Diabolo project, is being built between Schaarbeek and Mechelen and is being constructed for a speed of 220 km/h. There is also a project under way to renovate Mechelen railway station, when this line is completed, there will be a near-continuous stretch of high-speed line from Brussels to Amsterdam, save for the section between Mechelen and Antwerp. It is not known whether the Belgian government plans to construct a line between Mechelen and Antwerp, the track around Rotterdam station has curvatures that are too tight to allow trains to run at full speed and trains run on conventional track between Schiphol and Amsterdam

High-speed rail in Germany
–
Construction of the first German high-speed rail lines began shortly after that of the French LGVs. However, legal battles caused significent delays, so that the German InterCityExpress trains were deployed ten years after the TGV network was established. The ICE network is more integrated with pre-existing lines and trains as a result of the different settlement structure in Germany. ICE trains reached destinations in Austria and Switzerland soon after they entered service, starting in 2000, multisystem third-generation ICE trains entered the Netherlands and Belgium. The third generation of the ICE has a speed of 330 km/h and has reached speeds up to 363 km/h. Admission of ICE trains onto French LGVs was applied for in 2001, since June 2007, ICEs service Paris from Frankfurt and Saarbrücken via the LGV Est. Unlike the TGV in France or Shinkansen in Japan, Germany has experienced an accident on a high-speed service. In the Eschede train disaster of 1998, a first generation ICE experienced catastrophic wheel failure while travelling at 200 km/h near Eschede, of 287 passengers aboard,101 people died and 88 were injured in the resulting derailment. The accident was the result of faulty design and, following the crash. Thalys trains began running in Germany in 1997, from the Belgian HSL3 to Aachen, TGV POS trains began running in Germany in 2007, to Karlsruhe and Stuttgart using the Mannheim–Stuttgart and Karlsruhe–Basel high-speed lines. Germany has developed the Transrapid, a levitation train system. The Transrapid reaches speeds up to 550 km/h, a test track with a total length of 31.5 km operated in Emsland until Early 2012, when it was closed and dismantled. In China, Shanghai Maglev Train, a Transrapid technology based maglev built in collaboration with Siemens, Germany, has been operational since March 2004

High-speed rail in Italy
–
High-speed rail in Italy consists of two lines connecting most of the countrys major cities. The first line connects Turin to Salerno via Milan, Bologna, Florence, Rome and Naples, the runs from Turin to Venice via Milan. Trains are operated with a top speed of 300 km/h,25 million passengers traveled on the network in 2011. Passenger service is provided by Trenitalia and, since April 2012, by NTV-Italo, the first high-speed rail route in Italy, the Direttissima, opened in 1977, connecting Rome with Florence. The top speed on the line was 250 km/h, giving an end-to-end journey time of about 90 minutes with an speed of 200 km/h. This line used a 3 kV DC supply, high-speed service was introduced on the Rome-Milan line in 1988-89 with the ETR450 Pendolino train, with a top speed of 250 km/h and cutting travel times from about 5 hours to 4. The prototype train ETR X500 was the first Italian train to reach 300 km/h on the Direttissima on 25 May 1989, the Italian high-speed rail projects suffered relevant extra-costs and delay. Corruption and un-ethical behaviour played a key role, service on the high speed lines is provided by Trenitalia and privately owned NTV. It operates mainly on lines, AGV575, speeds up to 360 km/h, operated by NTV as Italo, ETR1000, operated by Trenitalia. Maximum speed of these trainsets is currently limited at 300 km/h while tracks are pending certification for 360 km/h operations, current limitations on the tracks set at 300 km/h the maximum operating speed of the trains. Along with the development of ETR1000 by AnsaldoBreda and Bombardier Transportation, secondary stock, ETR460, ETR485, tilting, speeds up to 250 km/h for other services, operated by Trenitalia. ETR470, tilting, speeds up to 250 km/h, operated by Trenitalia on services between Italy and Switzerland, new Pendolino ETR610 are being introduced to the Italy-Switzerland route. TGV trains also run on the Paris-Turin-Milan service, but do not use any high-speed line in Italy, the following high-speed rail lines are in use. The table shows minimum and maximum travel times, the Milan to Salerno is the major north-south corridor of the high-speed network. The Milan–Bologna segment opened on 13 December 2008 and its construction cost was about 6.9 billion euro. The 182 km line runs parallel to the Autostrada del Sole, there are eight connections with historic lines. At the Reggio Emilia interconnection a new designed by the Valencian architect Santiago Calatrava was opened in June 2013. Calatrava has also designed a bridge where the line crosses the A1 motorway

High-speed rail in the Netherlands
–
The Netherlands is connected to the European high-speed rail network with one dedicated high-speed line, HSL-Zuid, and improved traditional rail. Plans for a second dedicated high-speed line, HSL-Oost, have been cancelled, three high-speed train services have operated in the Netherlands, Thalys, InterCityExpress, and Fyra. Thalys started operating on the HSL-Zuid on 13 December 2009, HSL-Zuid is a 125 km high-speed railway line in the Netherlands. Using existing tracks from Amsterdam Centraal to Schiphol Airport, the dedicated high-speed line begins here and continues to Rotterdam Centraal, here, it connects to the HSL4, terminating at Antwerpen-Centraal. Den Haag Centraal and Breda are connected to the line by conventional railway lines. Services running at 160 km/h on the HSL-Zuid began on 7 September 2009 between Amsterdam and Rotterdam, from December 2009, Thalys trains from Amsterdam to Brussels and Paris have run on HSL-Zuid. From December 2012 to January 2013 the Fyra V250 trains ran on HSL-Zuid between Amsterdam and Brussels, only to have service suspended because of the quality of the Italian-made trains. The HSL-Zuid serves the stations, Amsterdam Centraal Schiphol Rotterdam Centraal Between Rotterdam. Hanzelijn is a 50 km high-speed railway line in the Netherlands, the maximum speed on the line is 200 km/h, though no Dutch domestic rolling stock can achieve speeds greater than 160 km/h. Only by clearing the line for International trains is the speed of 200 km/h reached. HSL-Oost is the name of a proposed high-speed line from Amsterdam into Germany via the Dutch cities of Utrecht and Arnhem. The scope of the project has now reduced, but it is expected that German ICE trains will be able to travel at 200 km/h from Amsterdam to Utrecht in the near future. Currently, ERTMS has been installed on the line, but the soil is soft, in 2009, a new feasibility study for the HSL-Oost after the year 2020 was promised by Minister of Transport, Public Works and Water Management Camiel Eurlings

Track gauge
–
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails. All vehicles on a network must have running gear that is compatible with the track gauge, as the dominant parameter determining interoperability, it is still frequently used as a descriptor of a route or network. There is a distinction between the gauge and actual gauge at some locality, due to divergence of track components from the nominal. Railway engineers use a device, like a caliper, to measure the actual gauge, the nominal track gauge is the distance between the inner faces of the rails. In current practice, it is specified at a distance below the rail head as the inner faces of the rail head are not necessarily vertical. In some cases in the earliest days of railways, the company saw itself as an infrastructure provider only. Colloquially the wagons might be referred to as four-foot gauge wagons, say and this nominal value does not equate to the flange spacing, as some freedom is allowed for. An infrastructure manager might specify new or replacement track components at a variation from the nominal gauge for pragmatic reasons. Track is defined in old Imperial units or in universally accepted metric units or SI units, Imperial units were established in United Kingdom by The Weights and Measures Act of 1824. In addition, there are constraints, such as the load-carrying capacity of axles. Narrow gauge railways usually cost less to build because they are lighter in construction, using smaller cars and locomotives, as well as smaller bridges, smaller tunnels. Narrow gauge is often used in mountainous terrain, where the savings in civil engineering work can be substantial. Broader gauge railways are generally expensive to build and require wider curves. There is no single perfect gauge, because different environments and economic considerations come into play, a narrow gauge is superior if ones main considerations are economy and tight curvature. For direct, unimpeded routes with high traffic, a broad gauge may be preferable, the Standard, Russian, and 46 gauges are designed to strike a reasonable balance between these factors. In addition to the general trade-off, another important factor is standardization, once a standard has been chosen, and equipment, infrastructure, and training calibrated to that standard, conversion becomes difficult and expensive. This also makes it easier to adopt an existing standard than to invent a new one and this is true of many technologies, including railroad gauges. The reduced cost, greater efficiency, and greater economic opportunity offered by the use of a common standard explains why a number of gauges predominate worldwide

Standard gauge
–
The standard gauge is a widely used railway track gauge. Approximately 55% of the lines in the world are this gauge, all high-speed rail lines, except those in Russia, Uzbekistan, and Finland, are standard gauge. The distance between the edges of the rails is defined to be 1435 mm except in the United States. It is also called the UIC gauge or UIC track gauge, as railways developed and expanded, one of the key issues was the track gauge to be used. The result was the adoption throughout a large part of the world of a gauge of 1435 mm. In North East England, some lines in colliery areas were 4 ft 8 in. All these lines had been widened to standard gauge by 1846, parts of the United States, mainly in the Northeast, adopted the same gauge, because some early trains were purchased from Britain. However, until well into the half of the 19th century, Britain. The American gauges converged as the advantages of equipment interchange became increasingly apparent, notably, all the 5 ft broad gauge track in the South was converted to standard gauge over the course of two days beginning on 31 May 1886. See Track gauge in the United States, snopes categorized this legend as false, but commented that. It is perhaps more fairly labelled as True, but for trivial, the historical tendency to place the wheels of horse-drawn vehicles approximately 5 feet apart probably derives from the width needed to fit a carthorse in between the shafts. Others were 4 ft 4 in or 4 ft 7 1⁄2 in, the English railway pioneer George Stephenson spent much of his early engineering career working for the coal mines of County Durham. He favoured 4 ft 8 in for wagonways in Northumberland and Durham, the Hetton and Springwell wagonways also used this gauge. Stephensons Stockton and Darlington railway was primarily to transport coal from mines near Shildon to the port at Stockton-on-Tees. The initial gauge of 4 ft 8 in was set to accommodate the existing gauge of hundreds of horse-drawn chaldron wagons that were already in use on the wagonways in the mines. The railway used this gauge for 15 years before a change was made to 4 ft 8 1⁄2 in gauge, George Stephenson used the 4 ft 8 1⁄2 in gauge for the Liverpool and Manchester Railway, authorised in 1826 and opened 30 September 1830. The success of this led to Stephenson and his son Robert being employed to engineer several other larger railway projects. Monkland and Kirkintilloch Railway, authorised 1824 and opened 1825, used 4 ft 6 in, Dundee and Newtyle Railway, authorised 1829 and opened 1831, used 4 ft 6 1⁄2 in

France
–
France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans 643,801 square kilometres and had a population of almost 67 million people as of January 2017. It is a unitary republic with the capital in Paris. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse, during the Iron Age, what is now metropolitan France was inhabited by the Gauls, a Celtic people. The area was annexed in 51 BC by Rome, which held Gaul until 486, France emerged as a major European power in the Late Middle Ages, with its victory in the Hundred Years War strengthening state-building and political centralisation. During the Renaissance, French culture flourished and a colonial empire was established. The 16th century was dominated by civil wars between Catholics and Protestants. France became Europes dominant cultural, political, and military power under Louis XIV, in the 19th century Napoleon took power and established the First French Empire, whose subsequent Napoleonic Wars shaped the course of continental Europe. Following the collapse of the Empire, France endured a succession of governments culminating with the establishment of the French Third Republic in 1870. Following liberation in 1944, a Fourth Republic was established and later dissolved in the course of the Algerian War, the Fifth Republic, led by Charles de Gaulle, was formed in 1958 and remains to this day. Algeria and nearly all the colonies became independent in the 1960s with minimal controversy and typically retained close economic. France has long been a centre of art, science. It hosts Europes fourth-largest number of cultural UNESCO World Heritage Sites and receives around 83 million foreign tourists annually, France is a developed country with the worlds sixth-largest economy by nominal GDP and ninth-largest by purchasing power parity. In terms of household wealth, it ranks fourth in the world. France performs well in international rankings of education, health care, life expectancy, France remains a great power in the world, being one of the five permanent members of the United Nations Security Council with the power to veto and an official nuclear-weapon state. It is a member state of the European Union and the Eurozone. It is also a member of the Group of 7, North Atlantic Treaty Organization, Organisation for Economic Co-operation and Development, the World Trade Organization, originally applied to the whole Frankish Empire, the name France comes from the Latin Francia, or country of the Franks

High-speed rail
–
High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. The first such system began operations in Japan in 1964 and was known as the bullet train. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design, only in Europe does HSR cross international borders. China has 22,000 kilometres of HSR as of end December 2016, while high-speed rail is most often designed for passenger travel, some high-speed systems also offer freight service. Multiple definitions for high-speed rail are in use worldwide, the European Union Directive 96/48/EC, Annex 1 defines high-speed rail in terms of, Infrastructure, track built specially for high-speed travel or specially upgraded for high-speed travel. Minimum Speed Limit, Minimum speed of 250 km/h on lines built for high speed. This must apply to at least one section of the line, Rolling stock must be able to reach a speed of at least 200 km/h to be considered high speed. Operating conditions, Rolling stock must be designed alongside its infrastructure for complete compatibility, safety and quality of service, category II – Existing tracks specially upgraded for high speeds, allowing a maximum running speed of at least 200 km/h. Category III – Existing tracks specially upgraded for high speeds, allowing a maximum running speed of at least 200 km/h, the UIC prefers to use definitions because they consider that there is no single standard definition of high-speed rail, nor even standard usage of the terms. They make use of the European EC Directive 96/48, stating that high speed is a combination of all the elements which constitute the system, infrastructure, rolling stock and operating conditions. The International Union of Railways states that high-speed rail is a set of unique features, many conventionally hauled trains are able to reach 200 km/h in commercial service but are not considered to be high-speed trains. These include the French SNCF Intercités and German DB IC, National domestic standards may vary from the international ones. Railways were the first form of land transportation and had an effective monopoly on passenger traffic until the development of the motor car. Speed had always been an important factor for railroads and they tried to achieve higher speeds. The line used three-phase current at 10 kilovolts and 45 Hz, on 23 October 1903, the S&H-equipped railcar achieved a speed of 206.7 km/h and on 27 October the AEG-equipped railcar achieved 210.2 km/h. These trains demonstrated the feasibility of electric high-speed rail, however, after the breakthrough of electric railroads, it was clearly the infrastructure – especially the cost of it – which hampered the introduction of high-speed rail. Several disasters happened – derailments, head-on collisions on single-track lines, collisions with traffic at grade crossings. The physical laws were well-known, i. e. if the speed was doubled, the radius should be quadrupled

SNCF
–
SNCF is Frances national state-owned railway company and manages the rail traffic in France and the Principality of Monaco. SNCF operates the national rail services, including the TGV. Its functions include operation of services for passengers and freight. SNCF employs more than 180,000 people in 120 countries around the globe, the railway network consists of about 32,000 km of route, of which 1,800 km are high-speed lines and 14,500 km electrified. About 14,000 trains are operated daily, since July 2013, SNCF headquarters are located in a Parisian suburb at 2, place aux Étoiles,93200 Saint Denis. In 2010 SNCF was ranked 22nd in France and 214th globally on the Fortune Global 500 list and it is the main business of the SNCF group, which in 2014 employed 245,763 people and had €27.2 billion of sales in 120 countries. The chairman of the SNCF group is Guillaume Pépy, SNCF operates almost all of Frances railway system, including the TGV, In the 1970s, SNCF began the TGV high-speed train programme with the intention of creating the worlds fastest railway network. It came to fruition in 1981, when the first TGV service, today, SNCF operates 1,850 km of designated high-speed track that accommodate more than 800 high-speed services per day. SNCF’s TGV trains carry more than 100 million passengers a year, TGV lines and TGV technology are now spread across several European countries in addition to South Korea.8 km/h. SNCF has a safety record. After nearly 30 years in operation, SNCF’s TGV system has experienced one fatal accident. SNCF also owns the tracks and the stations, since the 1990s, SNCF has been selling railway carriages to regional governments, with the creation of the Train Express Régional brand. SNCF also maintains a broad scope of business that includes work on freight lines, inter-city lines. SNCF experts provide logistics, design, construction, operations and maintenance services, SNCF operates the international ticketing agency, Voyages SNCF. SNCF has employees in 120 countries offering extensive overseas and cross border consulting and those projects include, Israel, Assistance and Training. SNCF International provides assistance to Israel Railways in every area of operations including projects to upgrade the networks general safety regulations. Other assistance and training programmes involve Infrastructure and the Traction Division, SNCF supervised the prime contractor responsible for construction of the Taiwan Railways Administration’s main high-speed rail line. It also trained rail traffic controllers, drivers, and crew members, on behalf of the Government of Taiwan, SNCF managed the high-speed railway Command Control Centre

Turbotrain
–
The Turbotrain was any of several French high-speed, gas turbine trains. The earliest Turbotrain entered service in 1967, for use on Frances SNCF intercity lines, there were several versions, four in total, with the last exiting service in 2005, and it is the Turbotrain that made advances possible for the TGV. In 1967, the SNCF converted a 2-car X4300 Class diesel multiple unit originally built by ANF Industrie starting in 1963. The new gas-turbine engine was installed into the car of this 2-car set. Trials started on 25 April 1967, the TGS reached 252 km/h on 15 October 1971. This is the first-generation of production Turbotrains and these ETG trains were four carriage trainsets which offered 188 seats and possessed one diesel engine and one gas turbine engine. The gas-turbine engine was a 820 kW Turbomeca Turmo IIIF3 gas-turbine Voith hydraulic, the ETGs entered service in 1971 on the Paris-Caen-Cherbourg. A total of 14 of these trainsets were manufactured from 1969-1972 by ANF. These trains were maintained at the Venissieux trainshed in Lyon for many years, electrification of the Grenoble line caused some trainsets to be shifted to work in Clermont Ferrand and Metz. These trains had five carriages with 280 seats and were built between 1972 and 1976 by ANF and MTE, forty-one RTG trainsets were manufactured for SNCF service. These trains were equipped with one 820 kW Turmo IIIF1 gas turbine in the cabs and one Turmo XII1,200 kW gas turbine in the odd-numbered cabs. Normally, the even-numbered 820 kW engine was shut down once the train reached cruising speeds, the RTG entered service in 1973 on the Strasbourg-Lyon and Lyon-Nantes lines, it subsequently entered service on the Paris-Caen-Cherbourg and Paris-Deauville-Dives-Cabourg lines in 1975. In later years, the SNCF RTG trainsets were modified to allow two RTG trains to be operated together by one driver as a multiple-unit train, six examples of the RTG were built by ANF for Amtrak and were dubbed Turboliners in the United States. The Egyptian National Railways purchased three enlarged 10-car turbotrains manufactured by ANF for a planned 160 km/h service on the 208 km route between Cairo and Alexandria. However, the trackage is not suitable for such speeds, four units of Turbotrains were introduced in Iran in 1974 with max speed of 160 km/h between Tehran-Mashhad that later in 2008 were converted to DMU by substitution of diesel instead of turbines. This experimental Turbotrain TGV001 set the speed record for gas turbine-powered rail vehicles with 318 km/h on 8 December 1972. The electrification in 1996 of the Paris-Caen-Cherbourg line moved the RTGs onto the Lyon-Bordeaux until 2005 and this TGV001 was a five-car trainset which possessed four gas-turbine engines with a total output of 6,500 hp and all axles motored. This train was tested over more than 34,000 miles running at over 200 km/h, of which almost half were covered at more than 257 km/h

Gas turbine
–
A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a turbine. The basic operation of the gas turbine is similar to that of the power plant except that the working fluid is air instead of water. Fresh atmospheric air flows through a compressor that brings it to higher pressure, energy is then added by spraying fuel into the air and igniting it so the combustion generates a high-temperature flow. This high-temperature high-pressure gas enters a turbine, where it expands down to the exhaust pressure, the turbine shaft work is used to drive the compressor and other devices such as an electric generator that may be coupled to the shaft. The energy that is not used for shaft work comes out in the exhaust gases, the purpose of the gas turbine determines the design so that the most desirable energy form is maximized. Gas turbines are used to power aircraft, trains, ships, electrical generators,50, Heros Engine — Apparently, Heros steam engine was taken to be no more than a toy, and thus its full potential not realized for centuries. 1000, The Trotting Horse Lamp was used by the Chinese at lantern fairs as early as the Northern Song dynasty. When the lamp is lit, the heated airflow rises and drives an impeller with horse-riding figures attached on it,1629, Jets of steam rotated an impulse turbine that then drove a working stamping mill by means of a bevel gear, developed by Giovanni Branca. 1678, Ferdinand Verbiest built a model carriage relying on a jet for power. 1791, A patent was given to John Barber, an Englishman and his invention had most of the elements present in the modern day gas turbines. The turbine was designed to power a horseless carriage,1861, British patent no.1633 was granted to Marc Antoine Francois Mennons for a Caloric engine. The patent shows that it was a gas turbine and the show it applied to a locomotive. Also named in the patent was Nicolas de Telescheff, a Russian aviation pioneer,1872, A gas turbine engine was designed by Franz Stolze, but the engine never ran under its own power. 1894, Sir Charles Parsons patented the idea of propelling a ship with a turbine, and built a demonstration vessel. This principle of propulsion is still of some use,1895, Three 4-ton 100 kW Parsons radial flow generators were installed in Cambridge Power Station, and used to power the first electric street lighting scheme in the city. 1899, Charles Gordon Curtis patented the first gas engine in the USA. 1900, Sanford Alexander Moss submitted a thesis on gas turbines, in 1903, Moss became an engineer for General Electrics Steam Turbine Department in Lynn, Massachusetts

1973 oil crisis
–
The 1973 oil crisis began in October 1973 when the members of the Organization of Arab Petroleum Exporting Countries proclaimed an oil embargo. The embargo occurred in response to United States support for Israel during the Yom Kippur War, by the end of the embargo in March 1974, the price of oil had risen from US$3 per barrel to nearly $12 globally, US prices were significantly higher. The embargo caused an oil crisis, or shock, with many short- and long-term effects on global politics and it was later called the first oil shock, followed by the 1979 oil crisis, termed the second oil shock. The embargo was a response to American involvement in the 1973 Yom Kippur War, six days after Egypt and Syria launched a surprise military campaign against Israel, the US supplied Israel with arms. In response to this, the Organization of Arab Petroleum Exporting Countries announced an oil embargo against Canada, Japan, the Netherlands, the United Kingdom, the crisis had a major impact on international relations and created a rift within NATO. Some European nations and Japan sought to disassociate themselves from United States foreign policy in the Middle East to avoid being targeted by the boycott, Arab oil producers linked any future policy changes to peace between the belligerents. To address this, the Nixon Administration began multilateral negotiations with the combatants and they arranged for Israel to pull back from the Sinai Peninsula and the Golan Heights. By January 18,1974, US Secretary of State Henry Kissinger had negotiated an Israeli troop withdrawal from parts of the Sinai Peninsula, the promise of a negotiated settlement between Israel and Syria was enough to convince Arab oil producers to lift the embargo in March 1974. The embargo occurred at a time of rising petroleum consumption by industrialized countries and coincided with an increase in oil imports by the worlds largest oil consumer. In the aftermath, targeted countries initiated a variety of policies to contain their future dependency. The 1973 oil price shock, with the accompanying 1973–74 stock market crash, was regarded as the first discrete event since the Great Depression to have a persistent effect on the US economy, the embargos success demonstrated Saudi Arabias diplomatic and economic power. It was the largest oil exporter and a politically and religiously conservative kingdom, in 1970, US oil production started to decline, exacerbating the embargos impact. Following this, Nixon named James E. Akins as US Ambassador to Saudi Arabia to audit US production capacity, the confidential results were alarming—no spare capacity was available and production could only decrease. The oil embargo had little effect on supply, according to Akins. OPEC was organized to resist pressure by the Seven Sisters to reduce oil prices, at first, OPEC operated as an informal bargaining unit for resource-rich third-world countries. OPEC confined its activities to gaining a share of the profits generated by oil companies. In the early 1970s it began to exert economic and political strength, on August 15,1971, the United States unilaterally pulled out of the Bretton Woods Accord. The US abandoned the Gold Exchange Standard whereby the value of the dollar had been pegged to the price of gold and all other currencies were pegged to the dollar, shortly thereafter, Britain followed, floating the pound sterling

Thus, the business expanded into marine, the next year, it constructed the first 1300 MW generator set for the Paluel power station, setting a world record with an output of 1500 MW. In 1978, Alsthom delivered its first TGV to SNCF, the TGV went on to break world rail speed records in 1981 and in 1990. It also set the endurance record for high-speed train lines in 2001. In 1986, Alsthom Belfort received an order from EDF for the largest gas turbine in the world, in 1988–89, holding company CGEE Alstom acquired ACEC Energie and ACEC Automatisme from the dissolution of Belgian electrical engineering company ACEC SA. Alstom acquired 100% of ACECs transport division, renaming it ACEC Transport, in 1991, Alstoms parent company CGE was renamed Alcatel Alsthom Compagnie Générale dElectricité, or Alcatel Alsthom for short. In 1994, GEC Alsthom acquired the vehicle manufacturer Linke-Hofmann-Busch from Salzgitter AG. In 1995, the acquired the remaining shares in the steam turbine manufacturer MAN Energie. In early 1998, GEC Alsthom acquired the electrical contractor Cegelec, in 1998, GEC-Alsthom bought Italian firm SASIB SpAs rail signalling subsidiary Sasib Railways, which included the former General Railway Signal. In June 1998, GEC Alsthom was listed on the Paris Stock Exchange, GEC, at the same time, the company name was changed to Alstom. In 1999, Alstoms energy division merged with ABB in a 50–50 joint company known as ABB Alstom Power, Alstom also bought Canadas Télécité, a passenger information and security solutions company, and sold its heavy-duty gas turbine business to General Electric. The next year, it bought out ABBs share in ABB Alstom Power, in 2000, Alstom sold its diesel engine businesses to MAN Group. It also acquired a 51% stake in Fiat Ferroviaria, the Italian rail manufacturer, in April 2003, Alstom sold its industrial turbine business to Siemens for €1.1 billion. By 2003, Alstom was facing a crisis due to poor sales and over $5 billion of debt liabilities. Alstoms share price had dropped 90% over two years, in 2004, the French state took a 21% stake in Alstom and received an EU-approved French government bailout worth €2.5 billion

These refugees had been expelled from Vienne by the Allobroges and were now encamped at the confluence of the Saône and Rhône rivers, dio Cassius says this task was to keep the two men from joining Mark Antony and bringing their armies into the developing conflict. The Roman foundation was at Fourvière hill and was officially called Colonia Copia Felix Munatia, a name invoking prosperity, the city became increasingly referred to as Lugdunum. The earliest translation of this Gaulish place-name as Desired Mountain is offered by the 9th-century Endlicher Glossary, in contrast, some modern scholars have proposed a Gaulish hill-fort named Lugdunon, after the Celtic god Lugus, and dúnon. It then became the capital of Gaul, partly due to its convenient location at the convergence of two rivers, and quickly became the main city of Gaul. Two emperors were born in city, Claudius, whose speech is preserved in the Lyon Tablet in which he justifies the nomination of Gallic senators. Today, the archbishop of Lyon is still referred to as Primat des Gaules, the Christians in Lyon were martyred for their beliefs under the reigns of various Roman emperors, most notably Marcus Aurelius and Septimus Severus. Local saints from this period include Blandina, Pothinus, and Epipodius, in the second century AD, the great Christian bishop of Lyon was the Easterner, Irenaeus.

Snowfalls are infrequent, over 50% of years do not experience a single snowfall, Massalia, whose name was probably adapted from an existing language related to Ligurian, was the first Greek settlement in France. It was established within modern Marseille around 600 BC by colonists coming from Phocaea on the Aegean coast of Asia Minor. The connection between Massalia and the Phoceans is mentioned in Thucydidess Peloponnesian War, he notes that the Phocaean project was opposed by the Carthaginians, the founding of Massalia has also been recorded as a legend.

Lille
–
Lille is a city in northern France, in French Flanders. On the Deûle River, near Frances border with Belgium, it is the capital of the Hauts-de-France region, archeological digs seem to show the area as inhabited by as early as 2000 BC, most notably in the modern-day quartiers of Fives, Wazemmes, and Vieux Lille. The legend of Lydéric and Phinaert puts the foundation of the city of Lille at 640, in the 8th century, the language of Old Low Franconian was spoken here, as attested by toponymic research. Lilles Dutch name is Rijsel, which comes from ter ijsel, the French equivalent has the same meaning, Lille comes from lîle. From 830 until around 910, the Vikings invaded Flanders, after the destruction caused by Norman and Magyar invasion, the eastern part of the region was ruled by various local princes. The first mention of the dates from 1066, apud Insulam. At the time, it was controlled by the County of Flanders, the County of Flanders thus extended to the left bank of the Scheldt, one of the richest and most prosperous regions of Europe. A notable local in this period was Évrard, who lived in the 9th century and participated in many of the days political, there was an important Battle of Lille in 1054. From the 12th century, the fame of the Lille cloth fair began to grow, in 1144 Saint-Sauveur parish was formed, which would give its name to the modern-day quartier Saint-Sauveur. Infante Ferdinand, Count of Flanders was imprisoned and the county fell into dispute, it would be his wife, Jeanne, Countess of Flanders and Constantinople and she was said to be well loved by the residents of Lille, who by that time numbered 10,000. He pushed the kingdoms of Flanders and Hainaut towards sedition against Jeanne in order to recover his land and she called her cousin, Louis VIII. He unmasked the imposter, whom Countess Jeanne quickly had hanged, in 1226 the King agreed to free Infante Ferdinand, Count of Flanders. Count Ferrand died in 1233, and his daughter Marie soon after, in 1235, Jeanne granted a city charter by which city governors would be chosen each All Saints Day by four commissioners chosen by the ruler. On 6 February 1236, she founded the Countesss Hospital, which one of the most beautiful buildings in Old Lille. It was in her honour that the hospital of the Regional Medical University of Lille was named Jeanne of Flanders Hospital in the 20th century, the Countess died in 1244 in the Abbey of Marquette, leaving no heirs. The rule of Flanders and Hainaut thus fell to her sister, Margaret II, Countess of Flanders, then to Margarets son, Lille fell under the rule of France from 1304 to 1369, after the Franco-Flemish War. The county of Flanders fell to the Duchy of Burgundy next, after the 1369 marriage of Margaret III, Countess of Flanders, Lille thus became one of the three capitals of said Duchy, along with Brussels and Dijon. By 1445, Lille counted some 25,000 residents, Philip the Good, Duke of Burgundy, was even more powerful than the King of France, and made Lille an administrative and financial capital

Bordeaux wine has been produced in the region since the 8th century, the historic part of the city is on the UNESCO World Heritage List as an outstanding urban and architectural ensemble of the 18th century. After Paris, Bordeaux has the highest number of preserved buildings of any city in France. In historical times, around 300 BC it was the settlement of a Celtic tribe, the Bituriges Vivisci, the name Bourde is still the name of a river south of the city. In 107 BC, the Battle of Burdigala was fought by the Romans who were defending the Allobroges, a Gallic tribe allied to Rome, the Romans were defeated and their commander, the consul Lucius Cassius Longinus, was killed in the action. The city fell under Roman rule around 60 BC, its importance lying in the commerce of tin, later it became capital of Roman Aquitaine, flourishing especially during the Severan dynasty. In 276 it was sacked by the Vandals, further ravage was brought by the same Vandals in 409, the Visigoths in 414 and the Franks in 498, beginning a period of obscurity for the city. In the late 6th century, the city re-emerged as the seat of a county and an archdiocese within the Merovingian kingdom of the Franks, the city started to play a regional role as a major urban center on the fringes of the newly founded Frankish Duchy of Vasconia. Around 585, a certain Gallactorius is cited as count of Bordeaux, the city was plundered by the troops of Abd er Rahman in 732 after storming the fortified city and overwhelming the Aquitanian garrison. After Duke Eudess defeat, the Aquitanian duke could still save part of its troops, the following year, the Frankish commander descended again over Aquitaine, but clashed in battle with the Aquitanians and left to take on hostile Burgundian authorities and magnates. In 745, Aquitaine faced yet another expedition by Charles sons Pepin and Carloman against Hunald, Hunald was defeated, and his son Waifer replaced him, who in turn confirmed Bordeaux as the capital city. During the last stage of the war against Aquitaine, it was one of Waifers last important strongholds to fall to King Pepin the Shorts troops. Next to Bordeaux, Charlemagne built the fortress of Fronsac on a hill across the border with the Basques, in 778, Seguin was appointed count of Bordeaux, probably undermining the power of the Duke Lupo, and possibly leading to the Battle of Roncevaux Pass that very year

In 2014, the city proper had 276,170 inhabitants, Strasbourgs metropolitan area had a population of 773,347 in 2013, making it the ninth largest metro area in France and home to 13% of the Grand Est regions inhabitants. The transnational Eurodistrict Strasbourg-Ortenau had a population of 915,000 inhabitants in 2014, Strasbourg is the seat of several European institutions, such as the Council of Europe and the Eurocorps, as well as the European Parliament and the European Ombudsman of the European Union. The city is also the seat of the Central Commission for Navigation on the Rhine, Strasbourgs historic city centre, the Grande Île, was classified a World Heritage site by UNESCO in 1988, the first time such an honour was placed on an entire city centre. The largest Islamic place of worship in France, the Strasbourg Grand Mosque, was inaugurated by French Interior Minister Manuel Valls on 27 September 2012. Economically, Strasbourg is an important centre of manufacturing and engineering, as well as a hub of road, rail, the port of Strasbourg is the second largest on the Rhine after Duisburg, Germany. Before the 5th century, the city was known as Argantorati, a Celtic Gaulish name Latinized first as Argentorate, after the 5h century, the city became known by a completely different name Gallicized as Strasbourg. That name is of Germanic origin and means Town of roads, Strasbourg is situated on the eastern border of France with Germany. This border is formed by the River Rhine, which forms the eastern border of the modern city. The historic core of Strasbourg however lies on the Grande Île in the River Ill, which flows parallel to, and roughly 4 kilometres from. The natural courses of the two eventually join some distance downstream of Strasbourg, although several artificial waterways now connect them within the city. This section of the Rhine valley is an axis of north-south travel, with river traffic on the Rhine itself. The city is some 400 kilometres east of Paris, in spite of its position far inland, Strasbourgs climate is classified as Oceanic, with warm, relatively sunny summers and cold, overcast winters. Precipitation is elevated from mid-spring to the end of summer, but remains largely constant throughout the year, on average, snow falls 30 days per year. The highest temperature recorded was 38.5 °C in August 2003. The lowest temperature recorded was −23.4 °C in December 1938.

Rennes is a city in the east of Brittany in northwestern France at the confluence of the Ille and the Vilaine. Rennes is the capital of the region of Brittany, as well as the Ille-et-Vilaine department, renness history goes back more than 2,000 years, at a time when it was a small Gallic village named Condate. Together with Vannes and Nantes, it was one of the cities of the historic province of Brittany. After the French Revolution, Rennes remained for most of its history a parliamentary, administrative, since the 1950s, Rennes has grown in importance through rural flight and its modern industrial development, partly automotive. The city developed extensive building plans to accommodate upwards of 200,000 inhabitants, during the 1980s, Rennes became one of the main centres in telecommunication and high technology industry. It is now a significant digital innovation centre in France, in 2015, the city is the tenth largest in France, with a metropolitan area of about 700,000 inhabitants. With more than 63,000 students in 2013, is also the eighth-largest university campus of France, the inhabitants of Rennes are called Rennais in French. In 2012, lExpress named Rennes as the most liveable city in France, Rennes is the administrative capital of the French department of Ille-et-Vilaine. It has a long history due to its location at the confluence of two rivers and its proximity to the regions from which arose various challenges to the borders of Brittany. Without inscriptions, as the Celtic practice was, the Redones coinage features a charioteer whose pony has a human head, large hoards of their coins were unearthed in the treasure of Amanlis found in June 1835 and that of Saint-Jacques-de-la-Lande, discovered in February 1941. The museum at Rennes contains a representative collection. In 57 BC the Redones joined the Gaulish coalition against Rome which was suppressed by Crassus, in 52 BC, the Redones responded to the call of Vercingetorix to furnish a large contingent of warriors. The oldest known Rennais is Titus Flavius Postuminus, known to us from his steles found in Rennes in 1969. As indicated by his name, he would have been born under the Flavian dynasty, under the reign of Titus, one of the steles tells us, in Latin, that he took charge over all the public affairs in the Civitas Riedonum. He was twice duumvir and flamen for life for Mars Mullo, during the Roman era, the strategic position of the town contributed to its importance. To the west the principal Roman route, via Osismii, stretched from Condate Riedonum to Vorgium, in 275, the threat of barbarians led to the erection of a robust brick wall around Rennes. The Holy See of Rennes had been established by 453, with a church having occupied the site of the current Rennes Cathedral since the start of the 6th century. One of the earliest bishops of Rennes, Melaine - who would become the patron saint - played an important role in the peace treaty between the Franks and the Armoricans in 497

Shinkansen
–
The Shinkansen is a network of high-speed railway lines in Japan operated by five Japan Railways Group companies. The nickname bullet train is used in English for these high-speed trains. The maximum operating speed is 320 km/h, test runs have reached 443 km/h for conventional rail in 1996, and up to a world record 603 km/h for maglev trains in April 2015. Shinkansen literally means new trunk line, referring to the rail line network. The name Superexpress, initially used for Hikari trains, was retired in 1972 but is used in English-language announcements. The original Tōkaidō Shinkansen, connecting the largest cities of Tokyo, carrying 151 million passengers per year, and at over 5 billion total passengers it has transported more passengers than any other high-speed line in the world. The service on the line operates much larger trains and at higher frequency than most other high speed lines in the world. At peak times, the line carries up to thirteen trains per hour in direction with sixteen cars each with a minimum headway of three minutes between trains. While the Shinkansen network has been expanding, Japans declining population is expected to cause ridership to decline over time, the recent expansion in tourism has boosted ridership marginally. Japan was the first country to build dedicated railway lines for high-speed travel, because of the mountainous terrain, the existing network consisted of 1,067 mm narrow-gauge lines, which generally took indirect routes and could not be adapted to higher speeds. Consequently, Japan had a greater need for new high-speed lines than countries where the standard gauge or broad gauge rail system had more upgrade potential. Other significant people responsible for its development were Tadanao Miki, Tadashi Matsudaira. They were responsible for much of the development of the first line. All three had worked on aircraft design during World War II, the popular English name bullet train is a literal translation of the Japanese term dangan ressha, a nickname given to the project while it was initially being discussed in the 1930s. The name stuck because of the original 0 Series Shinkansens resemblance to a bullet and these plans were abandoned in 1943 as Japans position in World War II worsened. However, some construction did commence on the line, several tunnels on the present-day Shinkansen date to the war-era project, by the mid-1950s the Tōkaidō Line was operating at full capacity, and the Ministry of Railways decided to revisit the Shinkansen project. In 1957, Odakyu Electric Railway introduced its 3000 series SE Romancecar train and this train gave designers the confidence that they could safely build an even faster standard gauge train. Thus the first Shinkansen, the 0 series, was built on the success of the Romancecar, in the 1950s, the Japanese national attitude was that railways would soon be outdated and replaced by air travel and highways as in America and many countries in Europe

Japan
–
Japan is a sovereign island nation in Eastern Asia. Located in the Pacific Ocean, it lies off the eastern coast of the Asia Mainland and stretches from the Sea of Okhotsk in the north to the East China Sea, the kanji that make up Japans name mean sun origin. 日 can be read as ni and means sun while 本 can be read as hon, or pon, Japan is often referred to by the famous epithet Land of the Rising Sun in reference to its Japanese name. Japan is an archipelago consisting of about 6,852 islands. The four largest are Honshu, Hokkaido, Kyushu and Shikoku, the country is divided into 47 prefectures in eight regions. Hokkaido being the northernmost prefecture and Okinawa being the southernmost one, the population of 127 million is the worlds tenth largest. Japanese people make up 98. 5% of Japans total population, approximately 9.1 million people live in the city of Tokyo, the capital of Japan. Archaeological research indicates that Japan was inhabited as early as the Upper Paleolithic period, the first written mention of Japan is in Chinese history texts from the 1st century AD. Influence from other regions, mainly China, followed by periods of isolation, from the 12th century until 1868, Japan was ruled by successive feudal military shoguns who ruled in the name of the Emperor. Japan entered into a period of isolation in the early 17th century. The Second Sino-Japanese War of 1937 expanded into part of World War II in 1941, which came to an end in 1945 following the bombings of Hiroshima and Nagasaki. Japan is a member of the UN, the OECD, the G7, the G8, the country has the worlds third-largest economy by nominal GDP and the worlds fourth-largest economy by purchasing power parity. It is also the worlds fourth-largest exporter and fourth-largest importer, although Japan has officially renounced its right to declare war, it maintains a modern military with the worlds eighth-largest military budget, used for self-defense and peacekeeping roles. Japan is a country with a very high standard of living. Its population enjoys the highest life expectancy and the third lowest infant mortality rate in the world, in ancient China, Japan was called Wo 倭. It was mentioned in the third century Chinese historical text Records of the Three Kingdoms in the section for the Wei kingdom, Wa became disliked because it has the connotation of the character 矮, meaning dwarf. The 倭 kanji has been replaced with the homophone Wa, meaning harmony, the Japanese word for Japan is 日本, which is pronounced Nippon or Nihon and literally means the origin of the sun. The earliest record of the name Nihon appears in the Chinese historical records of the Tang dynasty, at the start of the seventh century, a delegation from Japan introduced their country as Nihon

Transmission Voie-Machine
–
Transmission Voie-Machine is a form of in-cab signalling originally deployed in France and used on high-speed railway lines. TVM-300 was the first version, followed by TVM-430, TVM-300 was developed in the 1970s as part of the TGV project. At speeds of above 220 kilometres per hour, TGV trains run only on dedicated tracks designated as lignes à grande vitesse, at high-speeds it is not possible for a driver to accurately see colour-light based railway signals along the track-side. Signalling information is transmitted to the train and displayed as part of the train controls. The driver is shown the safe operating speed, displayed in kilometres per hour, the 1980s-developed TVM-430 system transmits more information than traditional signalling would allow, including gradient profiles and information about the state of signalling blocks further ahead. This high degree of automation does not remove the train from driver control, the TVM system was developed by the French group Compagnie de Signaux et dEntreprises Electriques, now part of Ansaldo STS. Two versions of TVM signalling, TVM-430 and TVM-300, are in use on the LGV, TVM-430, a newer system, was first installed on the LGV Nord to the Channel Tunnel and Belgium, and supplies trains with more information than TVM-300. TVM-430 was presented from a modular and flexible range of signalling system levels from TVM-400 up to TVM-440. The line is divided into blocks of about 1,500 metres. Dashboard instruments show the maximum permitted speed for a trains current block, the maximum permitted speed is based on factors such as the proximity of trains ahead, junction placement, speed restrictions, the top speed of the train and distance from the end of LGV route. Trains at high-speed take several kilometres to stop, since trains will require more than one signal block to slow down, drivers are alerted to reduce speed gradually, several blocks before any required stop. The signalling system is permissive, the driver of a train is permitted to proceed into a block section without first obtaining authorisation. Speed in this situation is limited to 30 kilometres per hour and if speed exceeds 35 km/h, the brake is applied. Once a route is set, or the centre has provided authorisation. The driver then acknowledges the authorization using a button on the control panel. This temporarily overrides the emergency braking system, which would stop the train when proceeding past the non-permissive markers ground loop. When trains enter or leave the LGV from lignes classiques, they pass over a loop which automatically switches the drivers dashboard indicators to the appropriate signalling system. For example, a leaving the LGV onto a French ligne classique would have its TVM signalling system deactivated

Land speed record for rail vehicles
–
Determination of the fastest rail vehicle in the world varies depending on the definition of rail. The world record for manned passenger trains is held by the L0 Series, the world record for conventional wheeled manned passenger trains is held by Frances specially tuned TGV. Reduced to three cars with higher voltage, larger wheels and higher-tension pantograph wires, it broke the record in April 2007. The fastest manned rail vehicle was a rocket sled, which carried USAF Colonel John Stapp at 1,017 km/h. Unmanned rocket sleds that ride on rails have reached over 10,400 km/h, legend, Arr, Disposition and number of elements forming the train. Power, DC, DC 3rd rail, AC, Single phase, Triphase, gas, Steam, Diesel-hydraulic, Propeller, Rocket, Jet. The following is a list of speed records for rail vehicles with electric traction motors, the following is a list of speed records for steam locomotives. The following is a list of speed records for rail vehicles that use air propulsion to move rail vehicles while the wheels are rolling along the track. Using an air cushion and a Monorail, the Aérotrain set on 5 March 1974 a mean speed of 417.6 km/h, the following are the lists of world record average operating speeds between two stations. The average speeds are measured by the time and the distance between the two stations

LGV Est
–
The Ligne à Grande Vitesse Est européenne, typically shortened to LGV Est, is a French high-speed rail line that connects Vaires-sur-Marne and Vendenheim. The line halved the time between Paris and Strasbourg and provides fast services between Paris and the principal cities of eastern France as well as Luxembourg, Germany. The LGV Est is a segment of the Main line for Europe project to connect Paris with Budapest with high-speed rail service, the line was built in two phases. Construction on the 300 km from Vaires-sur-Marne to Baudrecourt began in 2004, Construction on the 106 km second phase from Baudrecourt to Vendenheim began in June 2010, the second phase opened to commercial service on 3 July 2016. Opening of the phase was delayed after a train derailed near Eckwersheim during commissioning trials. A specially modified train performed a series of high-speed tests on the first phase of the LGV Est prior to its opening, in April 2007, it reached a top speed of 574.8 km/h, becoming the fastest conventional train and fastest train on a national rail system. The line passes through the French regions of Grand Est and Île-de-France, the first 300 km section of this new route, linking Vaires-sur-Marne near Paris to Baudrecourt in the Moselle, entered service on 10 June 2007. The second phase includes the 4, 200-metre Saverne Tunnel, in 1969, Metz politician Raymond Mondon requested a study of a fast train from Paris to Strasbourg along the route of the planned A4 autoroute. In 1970-71, the International Union of Railways developed a plan of fast intercity connections in continental Europe. Its connection between Paris and Strasbourg was very similar to the route of the LGV Est, the UIC master plan called for this line to be constructed shortly after Paris-Lyon and Paris-Brussels lines. In 1974, the director of SNCF confirmed that the wanted to follow the UIC master plan. Germany, which was developing the Transrapid maglev system, was reserved about the TGV system being developed by France. A1975 study concluded that the traffic to only Alsace. In 1982, recognizing German reluctance to extend the line into Germany, the LGV Est is a direct result of a project begun in 1985 with the establishment of a working group chaired by Claude Rattier and later by Philippe Essig. Their report provided the basis for design studies conducted in 1992-93. The initial 1980s plan extended along a corridor from Paris to Munich, in 1988, the German government agreed to a rail line from Paris to Frankfurt via Saarbrücken. The following year, Philippe Essig presented the route that would later be built and at the same time addressed the other problem and this route, further north than previous proposals, served Reims and Strasbourg. Financing of this called for contributions from local governments—a first in France for construction of a high-speed line—and the Grand Duchy of Luxembourg

Railway Gazette International
–
Railway Gazette International is a monthly business journal covering the railway, metro, light rail and tram industries worldwide. Railway Gazette International traces its history to May 1835 as The Railway Magazine, the Railway Gazette title dates from July 1905, created to cover railway commercial and financial affairs. In April 1914 it merged with The Railway Times, which incorporated Herapaths Railway Journal, around this time it also absorbed The Railway News. It then reflected all aspects of railway activity, particularly in the British Empire, in January 1964, it merged with sister publication Diesel Railway Traction and its frequency reduced from weekly to fortnightly. In October 1970, it was renamed Railway Gazette International and reduced in frequency to monthly, Railway Gazette International is part of the Railway Gazette Group, itself part of DVV Media Group. It was part of Reed Business Information until 1 April 2007

Shijiazhuang
–
Shijiazhuang, formerly romanized Shihkiachwang, is the capital and largest city of North Chinas Hebei Province. Administratively a prefecture-level city, it is about 263 kilometres southwest of Beijing, Shijiazhuangs total population ranked twelfth in mainland China. Shijiazhuang experienced dramatic growth after the founding of the Peoples Republic of China in 1949, the population of the metropolitan area has more than quadrupled in 30 years as a result of industrialization and infrastructural developments. From 2008 to 2011, Shijiazhuang implemented a plan which concluded with the reorganization of the city resulting in an increase of green areas and new buildings. A train station, airport and a system have been opened. The oldest name of the city was Shiyi, in pre-Han times, it was the site of the city of Shiyi in the state of Zhao, and from Han to Sui times it was the site of a county town with the same name. With the reorganization of government in the early period of the Tang dynasty. Shijiazhuang then became more than a local market town, subordinated to the flourishing city of Zhengding a few miles to the north. The growth of Shijiazhuang into one of Chinas major cities began in 1905, two years later the town became the junction for the new Shitai line, running from Shijiazhuang to Taiyuan, Shanxi. The city also became the centre of a road network. By 1935 it had far outstripped Zhengding as an economic centre, at the end of World War II the character of the city changed when it took on an administrative role as the preeminent city in western Hebei, and developed into an industrial city. Some industries, such as manufacturing, tobacco processing. On November 12,1947, the city was captured by Communist forces, in 1948, the city, formerly known as Shímén, was renamed Shijiazhuang. Today, the area is a memorial site, after 1949 the industrialisation of the city gathered momentum. Its population more than tripled in the decade 1948–58, in the 1950s, the city experienced a major expansion in the textile industry, with large-scale cotton spinning, weaving, printing, and dyeing works. In addition there are plants processing local farm produce, in the 1960s it was the site of a new chemical industry, with plants producing fertilizer and caustic soda. Shijiazhuang also became a base, with a tractor-accessory plant. In 1967, Tianjin was again carved out of Hebei, remaining a separate entity today, and thus the provincial capital was moved to Baoding

Zhengzhou
–
Zhengzhou is a Chinese city and the provincial capital of Henan Province in east-central China. As a prefecture-level city, it serves as the political, economic, technological. The city lies on the bank of the Yellow River. Zhengzhou has a population of 9,378,000 inhabitants with a population of 6,406,000. Zhengzhou is now a growing city. Greater Zhengzhou was named as one of the 13 emerging megacities or megalopolises in China in a July 2012 report by the Economist Intelligence Unit, the Shang dynasty established Aodu or Bodu in Zhengzhou. This prehistorical city had become abandoned as ruins long before the First Emperor of China in BC260, since 1950, archaeological finds in a walled city in Eastern Zhengzhou have provided evidence of Neolithic Shang dynasty settlements in the area. Outside this city, remains of public buildings and a complex of small settlements have been discovered. The site is identified with the Shang capital of Ao and is preserved in the Shang dynasty Ruins monument in Guanchen District. The Shang, who moved their capital due to frequent natural disasters. The site, nevertheless, remained occupied, Zhou tombs have also been discovered, legend suggests that in the Western Zhou period the site became the fief of a family named Guan. From this derives the name borne by the county since the late 6th century BC—Guancheng, the city first became the seat of a prefectural administration in AD587, when it was named Guanzhou. In 605 it was first called Zhengzhou—a name by which it has been virtually ever since. The name Zhengzhou came from the Sui dynasty, even though it was located in Chenggao, the government moved to the contemporary city during the Tang dynasty. It achieved its greatest importance under the Sui, Tang, and early Song dynasties, when it was the terminus of the New Bian Canal, which joined the Yellow River to the northwest. There, at a place called Heyin, a vast granary complex was established to supply the capitals at Luoyang and Changan to the west, in the Song period, however, the transfer of the capital eastward to Kaifeng robbed Zhengzhou of much of its importance. It was a capital during the five dynasties of Xia, Shang, Guan, Zheng, and Han, and a prefecture during the eight dynasties of Sui, Tang, Five Dynasties, Song, Jin, Yuan, Ming, and Qing. Zhengzhou thus became a rail junction and a regional center for cotton, grain, peanuts

Government of France
–
The Government of the French Republic exercises executive power. It is composed of a minister, who is the head of government. Senior ministers are titled as Ministers, whereas junior ministers are titled as Secretaries of State, a smaller and more powerful executive body, called the Council of Ministers, is composed only of the senior ministers, though some Secretaries of State may attend Council meetings. By comparison, the Government of France is equivalent to Her Majestys Government in the United Kingdom, all members of the French government are nominated by the President of the Republic on the advice of the Prime Minister. Members of the government are ranked in an order, which is established at the time of government formation. In this hierarchy, the Prime Minister is the head of government and he is nominated by the President of the Republic. After being nominated to lead a government, the Prime Minister nominee must propose a list of ministers to the President, the President can either accept or reject these proposed ministers. Ministers are ranked by importance, Ministers of State are senior ministers and it is an honorary rank, granted to some Ministers as a sign of prestige. Ministers are senior ministers, and are members of the Council of Ministers, Secretaries of State are junior ministers. This is the lowest rank in the French ministerial hierarchy, Secretaries work directly under a Minister, or sometimes directly under the Prime Minister. While the Council of Ministers does not include Secretaries of State as members, according to the Constitution of the French Fifth Republic, the government directs and decides the policy of the nation. In practice, the government writes bills to be introduced to parliament, all political decisions made by the government must be registered in the government gazette. All bills and some decrees must be approved by the Council of Ministers, furthermore, it is the Council of Ministers that defines the collective political and policy direction of the government, and takes practical steps to implement that direction. In addition to writing and implementing policy, the government is responsible for national defence, the workings of the government of France are based on the principle of collegiality. Meetings of the Council of Ministers take place every Wednesday morning at the Élysée Palace and they are presided over by the President of the Republic, who promotes solidarity and collegiality amongst government ministers. These meetings follow a set format, in the first part of a meeting, the Council deliberates over general interest bills, ordinances, and decrees. In the second part, the Council discusses individual decisions by each Minister regarding the appointment of civil servants. In addition, the Minister of Foreign Affairs provides the Council with weekly updates on important international issues, most government work, however, is done elsewhere

Ariane 1
–
Ariane 1 was the first rocket in the Ariane family of expendable launch systems. It was developed and operated by the European Space Agency, which had formed in 1973. Ariane 1 was the first launcher to be developed with the purpose of sending commercial satellites into geosynchronous orbit. Crucially, it was designed with the ability of sending a pair of satellites into orbit on a single launcher, thus reducing costs. As the size of satellites grew, Ariane 1 quickly gave way to the more powerful Ariane 2 and Ariane 3 launchers, which were heavily based upon the original rocket. The Ariane 4 was the last rocket to heavily draw upon the Ariane 1, as a result, the Europa IIIB proposal was scaled back and soon reemerged as the L3S. In January 1973, Willy Brandt, the Chancellor of Germany, formally agreed to the L3S project following a series of approaches by Georges Pompidou. On 21 September 1973, the agreement for the L3S, was signed. Under this agreement, the Europa III was formally cancelled, while the L3S would be developed as a multinational project. Development of L3S was seen as a crucial test for the ESA, according to author Brian Harvey, L3S was one of the major European engineering projects in the last quarter of the century. Other major companies involved included the French electronics firm Matra, Swedish manufacturer Volvo, development of the third stage was a major focus point for the project - prior to Ariane, only the United States had ever flown a launcher that utilised hydrogen-powered upper stages. In order to accommodate Ariane launches, the Guiana Space Centre at Kourou, the former Europa launch site was re-designated as ELA1 and was rebuilt with a lowered base and elongated tower. While all Ariane launches would take place from French Guiana, rocket construction would be performed at Aérospatiales facility in Les Mureaux, Paris. This was considered a coup for the programme as Intelsat was viewed as heavily committed to using the rival Space Shuttle launcher for a large number of its satellites at that point. One week later, ESA announced its commitment to a run of 10 Ariane 1 launchers. There was considerable pressure for Ariane to perform its maiden flight prior to end of 1979, despite fears that the launch would have to be delayed for a month, it was decided to resume the countdown for a second attempt. CAT was successfully placed into an orbit of 202km by 35, 753km, with lift-off mass of 210,000 kg, Ariane 1 was able to put in geostationary transfer orbit one satellite or two smaller of a maximal weight of 1,850 kg. The cost of program is estimated at 2 billion euros, the Ariane 1 was a four-stage vehicle

Concorde
–
Aérospatiale/BAC Concorde is a British-French turbojet-powered supersonic passenger jet airliner that was operated until 2003. It had a speed over twice the speed of sound at Mach 2.04. First flown in 1969, Concorde entered service in 1976 and continued flying for the next 27 years and it is one of only two supersonic transports to have been operated commercially, the other is the Soviet-built Tupolev Tu-144, which was operated for a much shorter period. Concorde was jointly developed and manufactured by Aérospatiale and the British Aircraft Corporation under an Anglo-French treaty, twenty aircraft were built, including six prototypes and development aircraft. Air France and British Airways were the airlines to purchase. The aircraft was used by wealthy passengers who could afford to pay a high price in exchange for Concordes speed. In the UK, any or all of the type are known simply as Concorde, the type was retired in 2003 after the crash of Air France Flight 4590, in which all passengers and crew were killed. The general downturn in the aviation industry after the September 11 attacks in 2001. The group met for the first time in February 1954 and delivered their first report in April 1955, at the time it was known that the drag at supersonic speeds was strongly related to the span of the wing. The team outlined a baseline configuration that looked like an enlarged Avro 730 and this same short span produced very little lift at low speed, which resulted in extremely long take-off runs and frighteningly high landing speeds. In an SST design, this would have required enormous engine power to lift off from existing runways, based on this, the group considered the concept of an SST infeasible, and instead suggested continued low-level studies into supersonic aerodynamics. Soon after, Johanna Weber and Dietrich Küchemann at the RAE published a series of reports on a new wing planform, the vortex will lower the air pressure and cause lift to be greatly increased. This effect had been noticed earlier, notably by Chuck Yeager in the Convair XF-92, Weber suggested that this was no mere curiosity, and the effect could be deliberately used to improve low speed performance. Küchemanns and Webers papers changed the nature of supersonic design almost overnight. Although the delta had already used on aircraft prior to this point. Such a layout would still have good supersonic performance inherent to the span, while also offering reasonable take-off. It would also need to have landing gear to produce the required angle of attack while still on the runway. Küchemann presented the idea at a meeting where Morgan was also present, test pilot Eric Brown recalls Morgans reaction to the presentation, saying that he immediately seized on it as the solution to the SST problem

LGV Sud Europe Atlantique
–
The LGV Sud Europe Atlantique, also known as the LGV Sud-Ouest or LGV LOcéane, is a high-speed railway line between Tours and Bordeaux, in France. It will be used by TGV trains operated by SNCF, the French national railway company and it is an extension of the LGV Atlantique. The line was inaugurated on 28 February 2017 and is expected to service on 2 July 2017. The line was built by consortium LISAE, which will be responsible for operating and maintaining the line until 2061, the trip between Paris and Bordeaux will take around two hours and ten minutes at a projected speed of 300 km/h. The inter-city links between Tours, Poitiers, Angoulême, and Bordeaux will also be improved and southwestern France will be connected to various parts of the country. The project is also a response to the traffic on the existing rail line. Train tracks are most efficiently used when all trains circulate at the speed and have identical stops. This congests the tracks and prevents their most efficient usage, dedicated tracks for the TGV therefore leave space on the existing tracks for many more freight and TER trains than just the number of removed TGV trains. New regional TER services will become possible, and could ease services that are currently crowded. The increase in trains on the existing track would ease truck traffic on the roads in the régions, as trains transport more and more goods. The project was sold as benefiting the economy. The construction of Phase 1 is expected to create 10,000 construction jobs a year for five years, jobs in the transport, commerce, and service sectors are expected to be created as well. Local businesses may their see competitiveness increase as their markets expand and this route will supplement – and partly supersede – the classic Paris–Bordeaux railway line. The line was built by consortium LISEA consisting of Vinci Concessions -33. 4%, Caisse des dépôts et consignations -25. 4%, Meridiam -22. 0%, the consortium will operate and maintain the line until 2061, and will charge tolls to train companies. The new high-speed route bypasses Libourne, shortening the distance traveled compared to the existing route. South of Poitiers, a connection allows trains to access the old tracks towards La Rochelle, the journey between Tours and Bordeaux will be shortened by around 50 minutes. 302 km of high-speed track was built together with a further 38 km of tracks that connect to the LGV. The new line is expected to increase ridership by about five million travellers

LGV Nord
–
The LGV Nord is a French 333-kilometre -long high-speed rail line, opened in 1993, that connects Paris to the Belgian border and the Channel Tunnel via Lille. With a maximum speed of 300 kilometres per hour, the line appreciably shortened rail journeys between Paris and Lille. Its extensions to the north and the south have reduced journey times to Great Britain and Benelux and its route is twinned with the A1 for 130 kilometres. As it is built in flat areas, the maximum incline is 25 metres per kilometre. Traffic is controlled by the Lille rail traffic centre, the LGV Nord begins at Arnouville-lès-Gonesse,16.6 kilometres from the Gare du Nord on the Paris–Lille railway line. After passing east of the forest of Ermenonville over the viaduc de Verberie, at Ablaincourt-Pressoir, a new station, Gare TGV Haute-Picardie, is served only by inter-regional TGVs. At Croisilles, Pas-de-Calais, a junction leads to the Agny link towards Arras, the LGV crosses the A1 autoroute at Seclin. After the Fretin junction, the LGV has a connection to the network at Lezennes. This junction is used for TGVs going to Lille-Flandres, all TGVs and some Eurostars stop at Lille-Europe. Non-stop Eurostars pass through a tunnel under the city of Lille at 200 kilometres per hour, the line passes south of Armentières and north of Hazebrouck. At Cassel, a provides a connection with Dunkirk. The LGV continues west, crossing the A26 autoroute at Zouafques and ends at Calais-Fréthun and this enables TGV service to Calais and Eurostars through the Channel Tunnel to London. The TGVs continue to Calais-Ville or reverse in either Calais stations and go on to Boulogne-sur-Mer and Étaples-Le Touquet, the route was much criticised, particularly by those in the Picardy region. The LGV crosses the region without a stop, Amiens in particular would have liked to have been on the line. The government judged a route via Amiens to be impracticable, as the Lille route demanded a straight line between Paris and Lille in order to give a reasonable Paris-Lille-London journey time. The LGV Picardie project would address this issue by serving Amiens, Amiens wanted a station closer to the town centre, stopping at Gare dAmiens. ² Arras station is reached via a branch of the LGV Nord that splits off near the village of Croisilles, rain had caused a hole to open up under the track, the hole dated from the First World War but had not been detected during construction. The front power car and the front four carriages derailed, out of the 200 passengers, one was slightly injured
