Rapid transit
–
Rapid transit, also known as heavy rail, metro, subway, tube, or underground, is a type of high-capacity public transport generally found in urban areas. The stations typically have high platforms, without steps inside the trains and they are typically integrated with other public transport and often operated by the same public transport authorities. However, some transit systems have at-grade intersections between a rapid transit line and a road or between two rapid transit lines. It is unchallenged in its ability to transport large numbers of people quickly over short distances with little use of land, variations of rapid transit include people movers, small-scale light metro, and the commuter rail hybrid S-Bahn. The worlds first rapid-transit system was the partially underground Metropolitan Railway which opened as a railway in 1863. In 1868, New York opened the elevated West Side and Yonkers Patent Railway, china has the largest number of rapid transit systems in the world. The worlds longest single-operator rapid transit system by length is the Shanghai Metro. The worlds largest single rapid transit service provider by both length of revenue track (665 miles and number of stations is the New York City Subway. The busiest rapid transit systems in the world by annual ridership are the Tokyo subway system, the Seoul Metropolitan Subway, the Moscow Metro, the Beijing Subway, Metro is the most common term for underground rapid transit systems used by non-native English speakers. One of these terms may apply to a system, even if a large part of the network runs at ground level. In Scotland, however, the Glasgow Subway underground rapid transit system is known as the Subway, in the US, underground mass transit systems are primarily known as subways, whereas the term metro is a shortened reference to a metropolitan area. In that vein, Chicagos commuter rail system, serving the area, is called Metra. Exceptions in naming rapid transit systems are Washington DCs subway system the Washington Metro, Los Angeles Metro Rail, and the Miami Metrorail, the opening of Londons steam-hauled Metropolitan Railway in 1863 marked the beginning of rapid transit. Initial experiences with steam engines, despite ventilation, were unpleasant, experiments with pneumatic railways failed in their extended adoption by cities. Electric traction was more efficient, faster and cleaner than steam, in 1890 the City & South London Railway was the first electric-traction rapid transit railway, which was also fully underground. Both railways were merged into London Underground. The 1893 Liverpool Overhead Railway was designed to use electric traction from the outset, budapest in Hungary and Glasgow, Chicago and New York all converted or purpose-designed and built electric rail services. Advancements in technology have allowed new automated services, hybrid solutions have also evolved, such as tram-train and premetro, which incorporate some of the features of rapid transit systems

Commuter rail
–
Trains operate following a schedule, at speeds varying from 50 to 200 km/h. Distance charges or zone pricing may be used and they primarily serve lower density suburban areas, and often share right-of-way with intercity or freight trains. Some services operate only during peak hours and others uses fewer departures during off peak hours, average speeds are high, often 50 km/h or higher. These higher speeds better serve the longer distances involved, some services include express services which skip some stations in order to run faster and separate longer distance riders from short-distance ones. The general range of commuter trains distance varies between 15 and 200 km, sometimes long distances can be explained by that the train runs between two or several cities. Distances between stations may vary, but are much longer than those of urban rail systems. In city centers the train either has a station or passes through the city centre with notably fewer station stops than those of urban rail systems. Toilets are often available on trains and in stations. Their ability to coexist with freight or intercity services in the same right-of-way can drastically reduce system construction costs, however, frequently they are built with dedicated tracks within that right-of-way to prevent delays, especially where service densities have converged in the inner parts of the network. Most such trains run on the standard gauge track. Some light rail systems may run on a narrower gauge, some countries, including Finland, India, Pakistan, Russia, Brazil and Sri Lanka, as well as San Francisco in the USA and Melbourne and Adelaide in Australia, use broad gauge track. The fact that the terminology is not standardised across countries further complicates matters, most S-bahns typically behave like commuter rail with most trackage not separated from other trains, and long lines with trains running between cities and suburbs rather than within a city. The distances between stations however, are usually short, in larger systems there is usually a high frequency metro-like central corridor in the city center where all the lines converge into. Typical examples of large city S-Bahns include Munich and Frankfurt, S-Bahns do also exist in some mid-size cities like Rostock and Magdeburg but behave more like typical commuter rail with lower frequencies and very little exclusive trackage. A similar network exists in Copenhagen called the S-tog, in Hamburg and Copenhagen, other, diesel driven trains, do continue where the S-Bahn ends. Regional rail usually provides rail services between towns and cities, rather than purely linking major population hubs in the way inter-city rail does, Regional rail operates outside major cities. Unlike Inter-city, it stops at most or all stations between cities and it provides a service between smaller communities along the line, and also connections with long-distance services at interchange stations located at junctions or at larger towns along the line. Alternative names are local train or stopping train, examples include the former BRs Regional Railways, Frances TER, Germanys DB Regio and South Koreas Tonggeun services

Train station
–
A train station, railway station, railroad station, or depot is a railway facility where trains regularly stop to load or unload passengers or freight. It generally consists of at least one platform and a station building providing such ancillary services as ticket sales. If a station is on a line, it often has a passing loop to facilitate traffic movements. The smallest stations are most often referred to as stops or, in parts of the world. Stations may be at level, underground, or elevated. Connections may be available to intersecting rail lines or other modes such as buses. In British usage, the station is commonly understood to mean a railway station unless otherwise qualified. In the United States, the most common term in contemporary usage is train station, Railway station and railroad station are less frequent. Outside North America, a depot is place where buses, trains, or other vehicles are housed and maintained and from which they are dispatched for service. The two-storey Mount Clare station in Baltimore, Maryland, which survives as a museum, first saw service as the terminus of the horse-drawn Baltimore. The oldest terminal station in the world was Crown Street railway station in Liverpool, built in 1830, as the first train on the Liverpool-Manchester line left Liverpool, the station is slightly older than the Manchester terminal at Liverpool Road. The station was the first to incorporate a train shed, the station was demolished in 1836 as the Liverpool terminal station moved to Lime Street railway station. Crown Street station was converted to a goods station terminal, the first stations had little in the way of buildings or amenities. The first stations in the modern sense were on the Liverpool and Manchester Railway, manchesters Liverpool Road Station, the second oldest terminal station in the world, is preserved as part of the Museum of Science and Industry in Manchester. It resembles a row of Georgian houses, dual-purpose stations can sometimes still be found today, though in many cases goods facilities are restricted to major stations. In rural and remote communities across Canada and the United States, such stations were known as flag stops or flag stations. Many stations date from the 19th century and reflect the architecture of the time. Countries where railways arrived later may still have such architecture, as later stations often imitated 19th-century styles, various forms of architecture have been used in the construction of stations, from those boasting grand, intricate, Baroque- or Gothic-style edifices, to plainer utilitarian or modernist styles

Lausanne Metro
–
Around a quarter of the system has been used for urban rail transport since 1877, when the route between the city centre and Ouchy opened as Switzerlands first public funicular railway. The network is owned by two companies and operated by a third. Of the two operating lines, the first is a limited-capacity light rail route, while the second is an automated metro which opened on 27 October 2008. When this opened, Lausanne replaced Rennes as the smallest city in the world to have a metro system. A third line is now planned, based on the same rubber-tyred metro technology, the Lausanne-Ouchy railway, the precursor to the M2 line of the Lausanne Metro, was inaugurated in 1877 as a funicular. In 1959 the first overhaul took place by transforming the funicular into a railway under the name métro. At that time, Flon and Gare CFF stations were demolished and replaced by concrete underground equivalents, the line was however always nicknamed La Ficelle by its users due to its funicular past and circulation above ground in the greenery for more than half of its run. The line was closed to all traffic on 21 January 2006. A bus service was put into operation to replace the then-closed La Ficelle until the opening of the new metro M2 line and this service was called Métrobus, the south loop linked Ouchy to the CFF station and the north loop linked the station to Montbenon. Lausanne originally had a system that opened in 1896. But the original Lausanne tram network closed entirely in 1964, a modern tramline, which ultimately became Lausanne Métro Line M1, opened on 24 May 1991, and began revenue service on 2 June 1991. In 2001, for marketing and public communication reasons, this line was renamed the M1 line by its operator TSOL, the M1 is a light rail line with a total of 15 stations, a dozen of which are at-grade and three of which are underground. The line is owned by a company named TSOL and this acronym is used by the commuters who use the line. Trains on the line are operated by the Transports publics de la région lausannoise, the M1 is a light rail line with a dozen surface stations and three underground. The line, which is 7. 8-kilometre long, links the centre of Lausanne, the line is generally single track. At most stations a passing loop is provided to allow trains to pass, exceptions to this are Bassenges, UNIL-Sorge and Provence stations, where the line is still single track serving one bidirectional platform. Unlike the later line 2, an automated or remotely controlled train was not planned when the line opened in 1991. There are a total of 18 of these original LRVs on the line, but after 20 years in service they were showing their age, and 2 were regularly out of use

Spanish solution
–
If there are three platforms with two tracks, generally the center platform will be a shared exit platform, as there is no benefit in segregating arriving passengers. At most locations doors for exit open a few seconds before those for entry, the principle was first used in 1895 at the King William Street tube station in London, but came into wide use on the Barcelona Metro in the 1930s. On people movers at airports there are dedicated platforms for boarding and alighting. This can have the advantage of preventing travellers heading in the wrong direction when alighting. The same principle is used on ferries, monorails, and cable cars, fairground rides such as roller coasters, lifts. At a terminal station where trains are bi-directional it is advantageous for the platform to be for boarding. This permits a train to enter on either track and remain in the station until it is ready to begin the next trip. Sé on the São Paulo Metro is a recent example, Line 1 Blue uses this model at stations like Sé, a busy station due to Line 3 integration, and Line 3 - Red uses this at Sé, Republic, Itaquera, Barra Funda, and Luz. In Hong Kong, the former KCRC reconstructed the platforms at the checkpoint terminus, Lo Wu Station, when the train stops, the doors on the island platform open and all passengers get off. Then the doors close and the doors on the platform open. In France, the principle is applied at the Line B platforms at Jean Jaurès on the Toulouse Metro, Peoples Republic of China Gongyuanqian and Xilang on the Guangzhou Metro. In Shanghai, the southbound Line 8 platform at Peoples Square, chengdu Metro Tianfu Square Line 1 platforms. First platform of Kurla railway station, first platform of Dombivli railway station. Changi Airport Skytrain terminus at every terminal between separation between Public and Transit Area between Terminal 2 and Terminal 3, choa Chu Kang LRT is the first station in Singapore to have an Island Platform upgraded to a Spanish solution platform. The main platform is still for boarding while the platforms are only for exits. Thailand Chachoengsao Junction on SRT Eastern Line, israel All 6 stations of the Carmelit underground funicular in Haifa. Schottenring, on Vienna U-Bahn line U2 at the platform of line U4, then, line U2 was extended to Stadion, Aspernstraße and Seestadt Aspern. Stuttgart Stadtbahn, Pragsattel, Mineralbäder Greece Omonoia, Irini and Neo Faliro in Athens Metro Line 1, italy Cologno Nord, a terminus station of the Milan M2 metro

Side platform
–
A side platform is a platform positioned to the side of a pair of tracks at a railway station, tram stop, or transitway. Dual side platform stations, one for direction of travel, is the basic station design used for double-track railway lines. Side platforms may result in a wider overall footprint for the station compared with a platform where a single width of platform can be shared by riders using either track. In some stations, the two platforms are connected by a footbridge running above and over the tracks. While a pair of platforms is often provided on a dual-track line. Where the station is close to a crossing the platforms may either be on the same side of the crossing road or alternatively may be staggered in one of two ways. With the near-side platforms configuration, each platform appears before the intersection, in some situations a single side platform can be served by multiple vehicles simultaneously with a scissors crossing provided to allow access mid-way along its length. Normally, the facilities of the station are located on the Up platform with the other platform accessed from a footbridge. However, in cases the stations main buildings are located on whichever side faces the town or village the station serves. Larger stations may have two platforms with several island platforms in between. Some are in a Spanish solution format, with two platforms and an island platform in between, serving two tracks

Island platform
–
An island platform is a station layout arrangement where a single platform is positioned between two tracks within a railway station, tram stop or transitway interchange. Island platforms are popular on twin-track routes due to pragmatic and cost-effective reasons, an alternative arrangement is to position side platforms on either side of the tracks. The historical use of island platforms depends greatly upon the location, the island platform layout is a popular, cost-effective and practical solution in modern railway systems. Island platforms allow facilities such as escalators, elevators, shops, toilets and this is essential for wheelchair accessible stations. An island platform makes it easier for users and the infirm to change services between tracks. Additionally, an island platform layout eliminates the need to construct a crossover or subway between two platforms, however, island platforms may become overcrowded, especially at busy stations, and this can lead to safety issues such as Clapham Common and Angel on the London Underground. However, for the tracks to diverge around the platform, extra width is required along the right-of-way on each approach to the station. Track centers vary for rail systems throughout the world but are normally 3 to 5 meters, if the island platform is 6 meters wide, the tracks have to slew out by the same distance. While this is not a problem on a new line that is being constructed, in addition, a single island platform makes it quite difficult to have through tracks, which are usually between the local tracks. A common configuration in busy locations on high speed lines is a pair of island platforms, high-speed trains can therefore pass straight through the station, while slow trains pass around the platforms. This arrangement also allows the station to serve as a point where trains can be passed by faster trains. The purpose of this design was to reduce unnecessary passenger congestion at a station with a high volume of passengers. Many of the stations on the Great Central Railway were constructed in this form and this was because the line was planned to connect to a Channel Tunnel. Island platforms are a normal sight on Indian railway stations. Almost all railway stations in India consist of island platforms, in Toronto,29 subway stations use island platforms. A slight disadvantage is that crossovers have to be rather long, in southern New Jersey and Philadelphia, PATCO uses island platforms in all of its 13 stations, to facilitate one-person train operation. Most elevated stations in Singapores Mass Rapid Transit system use island platforms, the exception is Dover MRT Station, which uses side platforms as it is built on an existing rail line. The planned Canberra MRT Station will also use side platforms, as it also be built on an existing rail line

Rack railway
–
A rack railway is a steep grade railway with a toothed rack rail, usually between the running rails. The trains are fitted with one or more cog wheels or pinions that mesh with this rack rail and this allows the trains to operate on steep grades above around 7 to 10%, which is the maximum for friction-based rail. Most rack railways are mountain railways, although a few are transit railways or tramways built to overcome a steep gradient in an urban environment. The first cog railway was the Middleton Railway between Middleton and Leeds in West Yorkshire, England, UK, where the first commercially successful steam locomotive, Salamanca and this used a rack and pinion system designed and patented in 1811 by John Blenkinsop. The first mountain cog railway was the Mount Washington Cog Railway in the US state of New Hampshire, the track was completed to reach the summit of Mount Washington in 1869. The first mountain railway in continental Europe was the Vitznau-Rigi-Bahn on Mount Rigi in Switzerland. A number of different rack systems have been developed, today, the majority of rack railways use the Abt system. Blenkinsops system remained in use for 25 years on the Middleton Railway, Rack systems place the rack rail halfway between the running rails, with the exception of some early Morgan rack installations. The first successful rack railway in the US was the Mount Washington Cog Railway, the first public trial of the Marsh rack on Mount Washington was made on August 29,1866, when only one quarter of a mile of track had been completed. The Mount Washington railway opened to the public on August 14,1868, the Riggenbach rack system was invented by Niklaus Riggenbach working at about the same time as, but independently from Marsh. Riggenbach was granted a French patent in 1863 based on a model which he used to interest potential Swiss backers. During this time, the Swiss Consul to the United States visited Marshs Mount Washington Cog Railway, eager to boost tourism in Switzerland, the government commissioned Riggenbach to build a rack railway up Rigi Mountain. Following the construction of a locomotive and test track in a quarry near Bern. The Riggenbach system is similar in design to the Marsh system and it uses a ladder rack, formed of steel plates or channels connected by round or square rods at regular intervals. The Riggenbach system suffers from the problem that its fixed ladder rack is more complex, following the success of the Vitznau-Rigi-Bahn, Riggenbach established the Maschinenfabrik der Internationalen Gesellschaft für Bergbahnen - a company that produced rack locomotives to his design. The Strub rack system was invented by Emil Strub in 1896 and it uses a rolled flat-bottom rail with rack teeth machined into the head approximately 100 mm apart. Safety jaws fitted to the locomotive engage with the underside of the head to prevent derailments, strubs US Patent, granted in 1898, also includes details of how the rack rail is integrated with the mechanism of a turnout. The best-known use of the Strub system is on the Jungfraubahn in Switzerland and it is the simplest rack system to maintain and has become increasingly popular
