Tyne and Wear Metro
The Tyne and Wear Metro, referred to locally as the Metro, is a rapid transit and light rail system in North East England, serving Newcastle upon Tyne, South Tyneside, North Tyneside and Sunderland in Tyne and Wear. It has been described as the first modern light rail system in the United Kingdom; the initial network opened between 1980 and 1984, using converted former railway lines, linked with new tunnel infrastructure. Extensions to the original network were opened in 1991 and 2002. In 2017/18 over 36 million passenger journeys were made on the network, which spans 77.5 kilometres and has two lines with a total of 60 stations, nine of which are underground. It is the second-largest of the four metro systems in the United Kingdom, after the London Underground; the system is operated by the local transport authority Nexus. Between 2010 and 2017 it was operated under contract by DB Regio Tyne & Wear Limited, a subsidiary of Arriva UK Trains. On 1 April 2017, this contract ended, Nexus took over direct operation of the system for a planned period of two years.
The present system uses much former railway infrastructure constructed between 1834 and 1882, with one of the oldest parts being the Newcastle & North Shields Railway which opened in 1839. In 1904, in response to tramway competition, taking away passengers, the North Eastern Railway started electrifying parts of their local railway network north of the River Tyne with a 600 V DC third-rail system, forming one of the earliest suburban electric networks, known as the Tyneside Electrics. In 1938, the line south of the Tyne between Newcastle and South Shields was electrified. In the 1960s under British Rail, the decision was made to de-electrify the Tyneside Electric network, convert it to diesel operation due to falling passenger numbers, the cost of renewing end of life electrical infrastructure and rolling stock; the Newcastle-South Shields line was de-electrified in 1963, the north Tyneside routes were de-electrified in 1967. This was viewed as a backward step, as the diesel trains were slower than the electric trains they replaced.
In the early 1970s, the poor local transport system was identified as one of the main factors holding back the region's economy, in 1971 a study was commissioned by the created Tyneside Passenger Transport Authority into how the transport system could be improved. This new system was intended to be the core of a new integrated transport network, with buses acting as feeders to purpose-built transport interchanges; the plans were approved by the Tyneside Metropolitan Railway Bill, passed by Parliament in July 1973. Around 70% of the funding for the scheme came from a central government grant, with the remainder coming from local sources. Three railway lines, totalling 26 miles were to be converted into Metro lines as part of the initial system; the converted railway lines were to be connected by around six miles of new infrastructure, built both to separate the Metro from the existing rail network, to create the new underground routes under Newcastle and Gateshead. Around four miles of the new infrastructure was in tunnels, while the remainder was either at ground level or elevated.
The elevated sections included the Queen Elizabeth II Bridge. Construction work began in October 1974, it was intended to be opened in stages between 1979 and 1981, however the first part of the original network opened in August 1980, the remainder opened in stages until March 1984. The final cost of the project in 1984 prices was £265 million; some extensions to the original system have since been built. A short 3.5 km extension from Bank Foot to Newcastle Airport was opened in 1991, using a further part of the former Ponteland branch. In 2002 an 18.5 km extension was opened from Pelaw to South Hylton via Sunderland. Costing £100 million, this extension used part of the existing Durham Coast Line to Sunderland, but did not take it over. Three intermediate stations on the route were rebuilt, three new ones were added. Within Sunderland, 4.5 km of a former freight line, abandoned in 1984 was reused for the route between Sunderland station and South Hylton, becoming the second Metro segment to be built on a disused line.
The opening dates of the services and stations are as follows: The Tyne and Wear Metro was the first railway in the UK to operate using the metric system
A metro station or subway station is a railway station for a rapid transit system, which as a whole is called a "metro" or "subway". A station provides a means for passengers to purchase tickets, board trains, evacuate the system in the case of an emergency; the location of a metro station is planned to provide easy access to important urban facilities such as roads, commercial centres, major buildings and other transport nodes. Most stations are located underground, with entrances/exits leading up to street level; the bulk of the station is positioned under land reserved for public thoroughfares or parks. Placing the station underground reduces the outside area occupied by the station, allowing vehicles and pedestrians to continue using the ground-level area in a similar way as before the station's construction; this is important where the station is serving high-density urban precincts, where ground-level spaces are heavily utilised. In other cases, a station may be elevated above a road, or at ground level depending on the level of the train tracks.
The physical and economic impact of the station and its operations will be greater. Planners will take metro lines or parts of lines at or above ground where urban density decreases, extending the system further for less cost. Metros are most used in urban cities, with great populations. Alternatively, a preexisting railway land corridor is re-purposed for rapid transit. At street level the logo of the metro company marks the entrances/exits of the station. Signage shows the name of the station and describes the facilities of the station and the system it serves. There are several entrances for one station, saving pedestrians from needing to cross a street and reducing crowding. A metro station provides ticket vending and ticket validating systems; the station is divided into an unpaid zone connected to the street, a paid zone connected to the train platforms. The ticket barrier allows passengers with valid tickets to pass between these zones; the barrier may operated by staff or more with automated turnstiles or gates that open when a transit pass is scanned or detected.
Some small metro systems dispense with paid zones and validate tickets with staff in the train carriages. Access from the street to ticketing and the train platform is provided by stairs, escalators and tunnels; the station will be designed to minimise overcrowding and improve flow, sometimes by designating tunnels as one way. Permanent or temporary barriers may be used to manage crowds; some metro stations have direct connections to important nearby buildings. Most jurisdictions mandate; this is resolved with elevators, taking a number of people from street level to the unpaid ticketing area, from the paid area to the platform. In addition, there will be stringent requirements for emergencies, with backup lighting, emergency exits and alarm systems installed and maintained. Stations are a critical part of the evacuation route for passengers escaping from a disabled or troubled train. A subway station may provide additional facilities, such as toilets and amenities for staff and security services, such as Transit police.
Some metro stations are interchanges, serving to transfer passengers between lines or transport systems. The platforms may be multi-level. Transfer stations handle more passengers than regular stations, with additional connecting tunnels and larger concourses to reduce walking times and manage crowd flows. In some stations where trains are automated, the entire platform is screened from the track by a wall of glass, with automatic platform-edge doors; these open, like elevator doors, only when a train is stopped, thus eliminate the hazard that a passenger will accidentally fall onto the tracks and be run over or electrocuted. Control over ventilation of the platform is improved, allowing it to be heated or cooled without having to do the same for the tunnels; the doors add cost and complexity to the system, trains may have to approach the station more so they can stop in accurate alignment with them. Metro stations, more so than railway and bus stations have a characteristic artistic design that can identify each stop.
Some have frescoes. For example, London's Baker Street station is adorned with tiles depicting Sherlock Holmes; the tunnel for Paris' Concorde station is decorated with tiles spelling the Déclaration des Droits de l'Homme et du Citoyen. Every metro station in Valencia, Spain has a different sculpture on the ticket-hall level. Alameda station is decorated with fragments of white tile, like the dominant style of the Ciutat de les Arts i les Ciències; each of the original four stations on Line 8 of the Beijing Subway is decorated traditionally with elements of Chinese culture. On the Tyne and Wear Metro, the station at Newcastle United's home ground St James' Park is decorated in the clubs famous black and white stripes; each station of the Red Line and Purple Line subway in Los Angeles was built with different artwork and decorating schemes, such as murals, tile artwork and sculptural benches. Every station of the Mexico City Metro is prominently identified by a unique icon in addition to its name, because the city had high illiteracy rates at the time the system was designed.
Some metro systems, such as those of Naples, Moscow, St. Petersburg, Kiev, Lisbon and Prague are famous for their beautiful architecture and public art; the Paris Métro is famous for its art nouveau station entrances.
England is a country, part of the United Kingdom. It shares land borders with Wales to Scotland to the north-northwest; the Irish Sea lies west of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south; the country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Palaeolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century, since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world; the English language, the Anglican Church, English law – the basis for the common law legal systems of many other countries around the world – developed in England, the country's parliamentary system of government has been adopted by other nations.
The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation. England's terrain is chiefly low hills and plains in central and southern England. However, there is upland and mountainous terrain in the west; the capital is London, which has the largest metropolitan area in both the United Kingdom and the European Union. England's population of over 55 million comprises 84% of the population of the United Kingdom concentrated around London, the South East, conurbations in the Midlands, the North West, the North East, Yorkshire, which each developed as major industrial regions during the 19th century; the Kingdom of England – which after 1535 included Wales – ceased being a separate sovereign state on 1 May 1707, when the Acts of Union put into effect the terms agreed in the Treaty of Union the previous year, resulting in a political union with the Kingdom of Scotland to create the Kingdom of Great Britain. In 1801, Great Britain was united with the Kingdom of Ireland to become the United Kingdom of Great Britain and Ireland.
In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain and Northern Ireland. The name "England" is derived from the Old English name Englaland, which means "land of the Angles"; the Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages. The Angles came from the Anglia peninsula in the Bay of Kiel area of the Baltic Sea; the earliest recorded use of the term, as "Engla londe", is in the late-ninth-century translation into Old English of Bede's Ecclesiastical History of the English People. The term was used in a different sense to the modern one, meaning "the land inhabited by the English", it included English people in what is now south-east Scotland but was part of the English kingdom of Northumbria; the Anglo-Saxon Chronicle recorded that the Domesday Book of 1086 covered the whole of England, meaning the English kingdom, but a few years the Chronicle stated that King Malcolm III went "out of Scotlande into Lothian in Englaland", thus using it in the more ancient sense.
According to the Oxford English Dictionary, its modern spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, in which the Latin word Anglii is used; the etymology of the tribal name itself is disputed by scholars. How and why a term derived from the name of a tribe, less significant than others, such as the Saxons, came to be used for the entire country and its people is not known, but it seems this is related to the custom of calling the Germanic people in Britain Angli Saxones or English Saxons to distinguish them from continental Saxons of Old Saxony between the Weser and Eider rivers in Northern Germany. In Scottish Gaelic, another language which developed on the island of Great Britain, the Saxon tribe gave their name to the word for England. An alternative name for England is Albion; the name Albion referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus the 4th-century BC De Mundo: "Beyond the Pillars of Hercules is the ocean that flows round the earth.
In it are two large islands called Britannia. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, i.e. it was written in the Graeco-Roman period or afterwards. The word Albion or insula Albionum has two possible origins, it either derives from a cognate of the Latin albus meaning white, a reference to the white cliffs of Dover or from the phrase the "island of the Albiones" in the now lost Massaliote Periplus, attested through Avienus' Ora Maritima to which the former served as a source. Albion is now applied to England in a more poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England and made popular by its use in Arthurian legend; the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximate
World Geodetic System
The World Geodetic System is a standard for use in cartography and satellite navigation including GPS. This standard includes the definition of the coordinate system's fundamental and derived constants, the ellipsoidal Earth Gravitational Model, a description of the associated World Magnetic Model, a current list of local datum transformations; the latest revision is WGS 84, established in 1984 and last revised in 2004. Earlier schemes included WGS 72, WGS 66, WGS 60. WGS 84 is the reference coordinate system used by the Global Positioning System; the coordinate origin of WGS 84 is meant to be located at the Earth's center of mass. The WGS 84 meridian of zero longitude is the IERS Reference Meridian, 5.3 arc seconds or 102 metres east of the Greenwich meridian at the latitude of the Royal Observatory. The WGS 84 datum surface is an oblate spheroid with equatorial radius a = 6378137 m at the equator and flattening f = 1/298.257223563. The polar semi-minor axis b equals a × = 6356752.3142 m. WGS 84 uses the Earth Gravitational Model 2008.
This geoid defines the nominal sea level surface by means of a spherical harmonics series of degree 360. The deviations of the EGM96 geoid from the WGS 84 reference ellipsoid range from about −105 m to about +85 m. EGM96 differs from the original WGS 84 geoid, referred to as EGM84. WGS 84 uses the World Magnetic Model 2015v2; the new version of WMM 2015 became necessary due to extraordinarily large and erratic movements of the north magnetic pole. The next regular update will occur in late 2019. Efforts to supplement the various national surveying systems began in the 19th century with F. R. Helmert's famous book Mathematische und Physikalische Theorien der Physikalischen Geodäsie. Austria and Germany founded the Zentralbüro für die Internationale Erdmessung, a series of global ellipsoids of the Earth were derived. A unified geodetic system for the whole world became essential in the 1950s for several reasons: International space science and the beginning of astronautics; the lack of inter-continental geodetic information.
The inability of the large geodetic systems, such as European Datum, North American Datum, Tokyo Datum, to provide a worldwide geo-data basis Need for global maps for navigation and geography. Western Cold War preparedness necessitated a standardised, NATO-wide geospatial reference system, in accordance with the NATO Standardisation AgreementIn the late 1950s, the United States Department of Defense, together with scientists of other institutions and countries, began to develop the needed world system to which geodetic data could be referred and compatibility established between the coordinates of separated sites of interest. Efforts of the U. S. Army and Air Force were combined leading to the DoD World Geodetic System 1960; the term datum as used here refers to a smooth surface somewhat arbitrarily defined as zero elevation, consistent with a set of surveyor's measures of distances between various stations, differences in elevation, all reduced to a grid of latitudes and elevations. Heritage surveying methods found elevation differences from a local horizontal determined by the spirit level, plumb line, or an equivalent device that depends on the local gravity field.
As a result, the elevations in the data are referenced to the geoid, a surface, not found using satellite geodesy. The latter observational method is more suitable for global mapping. Therefore, a motivation, a substantial problem in the WGS and similar work is to patch together data that were not only made separately, for different regions, but to re-reference the elevations to an ellipsoid model rather than to the geoid. In accomplishing WGS 60, a combination of available surface gravity data, astro-geodetic data and results from HIRAN and Canadian SHORAN surveys were used to define a best-fitting ellipsoid and an earth-centered orientation for each of selected datum; the sole contribution of satellite data to the development of WGS 60 was a value for the ellipsoid flattening, obtained from the nodal motion of a satellite. Prior to WGS 60, the U. S. Army and U. S. Air Force had each developed a world system by using different approaches to the gravimetric datum orientation method. To determine their gravimetric orientation parameters, the Air Force used the mean of the differences between the gravimetric and astro-geodetic deflections and geoid heights at selected stations in the areas of the major datums.
The Army performed an adjustment to minimize the difference between astro-geodetic and gravimetric geoids. By matching the relative astro-geodetic geoids of the selected datums with an earth-centered gravimetric geoid, the selected datums were reduced to an earth-centered orientation. Since the Army and Air Force systems agreed remarkably well for the NAD, ED and TD areas, they were consolidated and became WGS 60. Improvements to the global system included the Astrogeoid of Irene Fischer and the astronautic Mercury datum. In January 1966, a World Geodetic System Committee composed of representatives from the United States Army and Air Force was charged with developing an improved WGS, needed to satisfy mapping and geodetic requirements.

Newcastle Airport Metro station
Airport is a terminus station of the Green line of the Tyne and Wear Metro that serves Newcastle Airport, Newcastle upon Tyne. The station's platforms and ticket hall are situated a short distance south of the airport's terminal building, with a covered walkway running between them; the Airport extension, encompassing both Airport station and the intermediate Callerton Parkway station, was opened on 17 November 1991, having cost £12 million to construct. Prior to this date the Metro's Green line terminated 2 miles to the south-east at Bank Foot, with passengers heading to the airport having to alight there and take the M77 shuttle bus to the airport; the vast majority of the route of the extension was in place, having been opened in 1905 as part of the Ponteland and Darras Hall Branch of the North Eastern Railway. Although the line no longer reached Ponteland or Darras Hall, enough of it remained that building the extension only required around 0.2 miles of new right-of-way. In 2014 a survey conducted by the Consumers Association found that the Metro service from the Airport was one of the highest rated airport rail links in the country for customer satisfaction.
Only the Intercity train link to Birmingham International Airport was rated higher. Services towards South Hylton via Newcastle upon Tyne and Sunderland city centres operate every 12 minutes during the daytime and every 15 minutes during the evening and on Sundays, with trains taking around 24 minutes to reach central Newcastle and 55 minutes to reach Sunderland station. Services commence at 05:37 on weekdays, with starts on Saturday and Sunday; the last service to run the full length of the Green line to South Hylton departs at 22:39. Additional trains depart until 00:01, only taking passengers as far as Regent Centre before continuing empty to the Metro depot. Airport station information
A railway platform is an area alongside a railway track providing convenient access to trains. All stations have some form of platform, with larger stations having multiple platforms; the world's longest station platform is at Gorakhpur Junction in India at 1,355.40 metres. The Appalachian Trail station in the United States, at the other extreme, has a platform, only long enough for a single bench. Among some United States train conductors the word "platform" has entered usage as a verb meaning "to berth at a station", as in the announcement: "The last two cars of this train will not platform at East Rockaway"; the most basic form of platform consists of an area at the same level as the track resulting in a large height difference between the platform and the train floor. This would not be considered a true platform; the more traditional platform is elevated relative to the track but lower than the train floor, although ideally they should be at the same level. The platform is higher than the train floor, where a train with a low floor serves a station built for trains with a high floor, for example at the Dutch stations of the DB Regionalbahn Westfalen.
On the London Underground some stations are served by both District line and Piccadilly line trains, the Piccadilly trains have lower floors. A tram stop is in the middle of the street; the latter requires extra care by other traffic to avoid accidents. Both types of tram stops can be seen in the tram networks of Toronto. Sometimes a tram stop is served by ordinary trams with rather low floors and metro-like light rail vehicles with higher floors, the tram stop has a dual-height platform, as in Amstelveen, Netherlands. A train station may be served by heavy-rail and light-rail vehicles with lower floors and have a dual- height platform, as on the RijnGouweLijn in the Netherlands. Platform types include side platform, split platform and island platform. A bay platform is one at which the track terminates, i.e. a siding. Trains serving a bay platform must reverse out. A side platform is the more usual type, alongside tracks where the train arrives from one end and leaves towards the other. An island platform has through platforms on both sides.
To reach an island platform there may be a tunnel, or a level crossing. A variant on the side platform is the spanish solution which has platforms on both sides of a single through track. Most stations have their platforms numbered consecutively from 1. At Bristol Temple Meads platforms 3 through to 12 are split along their length with odd numbered platforms facing north and east and facing south and west, with a small signal halfway along the platform. Some, such as London Waterloo East, use letters instead of numbers. In the US, a designated place where a train can arrive is referred to as a "track"; the term "platform" is used in the US but refers to the structure rather than a designated place for a train arriving. Therefore an island platform would be described as one platform with two tracks. In some cases, there are numbered tracks which are used only for through traffic and do not have platform access. In other English-speaking countries, "platform" can refer to both the structure or to a designated place for trains arriving.
Therefore an island platform might have two numbered platforms. Some of the station facilities are located on the platforms. Where the platforms are not adjacent to a station building some form of shelter or waiting room is provided, employee cabins may be present; the weather protection offered varies from little more than a roof with open sides, to a closed room with heating or air-conditioning. There may be benches, ticket counters, drinking fountains, trash boxes, static timetables or dynamic displays with information about the next train. There are loudspeakers as part of a public address system; the PA system is used where dynamic timetables or electronic displays are not present. A variety of information is presented, including destinations and times, cancellations, platform changes, changes in routes and destinations, the number of carriages in the train and the location of first class or luggage compartments, supplementary fee or reservation requirements; some metro stations have platform screen doors between the tracks.
They provide more safety, they allow the heating or air conditioning in the station to be separated from the ventilation in the tunnel, thus being more efficient and effective. They have been installed in most stations of the Singapore MRT and the Hong Kong MTR, stations on the Jubilee Line Extension in London. Platforms should be sloped upwards towards the platform edge to prevent wheeled objects such as trolleys and wheelchairs from rolling away and into the path of the train. Many platforms have a cavity underneath an overhanging edge so that people who may fall off the
