Platform Gap
A platform gap (also known technically as the platform train interface or PTI in some countries) is the space between a train car (or other mass transit vehicle) and the edge of the station platform, often created by geometric constraints, historic legacies, or use of partially compatible equipment. Many high-quality bus rapid transit (BRT) systems also use high platforms at station stops to allow fast and efficient level boarding and alighting, but potentially leaving hazardous gaps between the platforms and the buses. Alignment setups such as Kassel curbs help to reduce platform gaps without requiring time-consuming manual alignment at each BRT station stop. Straight platforms The ideal platform would be straight and align perfectly with a train or other large vehicle. Even in this case, a small gap between the conveyances and the platform is necessary to allow the vehicles to move freely without rubbing against the platform edge. In 2007, the Long Island Rail Road regarded a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Rail Line
The East Rail line () is one of ten lines of the Mass Transit Railway (MTR) system in Hong Kong. It used to be one of the three lines of the Kowloon–Canton Railway (KCR) network. It was known as the KCR British Section () from 1910 to 1996, and the KCR East Rail () from 1996 to 2007. East Rail was the only railway line of the Kowloon-Canton Railway Corporation (KCRC) following the closure of the Sha Tau Kok Railway and before the construction of ''KCR West Rail'' (later renamed West Rail line, now part of the Tuen Ma line). The railway line starts at Admiralty on Hong Kong Island and branches in the north at Sheung Shui to terminate at Lo Wu or Lok Ma Chau stations. Both are border crossing points into Shenzhen. All of the stations on the line except Admiralty, Exhibition Centre and Hung Hom are at-grade or elevated. The distance between Hung Hom and Lo Wu stations is . The total distance of the line (including the Lok Ma Chau Spur line) is approximately , making it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Super-elevation
The cant of a railway track or camber of a road (also referred to as superelevation, cross slope or cross fall) is the rate of change in elevation (height) between the two rails or edges. This is normally greater where the railway or road is curved; raising the outer rail or the outer edge of the road creates a banked turn, thus allowing vehicles to maneuver through the curve at higher speeds than would otherwise be possible were the surface flat or level. Rail On railways, cant helps a train steer around a curve, keeping the wheel flanges from touching the rails, minimizing friction, wear and rail squeal. The main functions of cant are the following: * Improve distribution of the load across both rails * Reduce wear on rails and wheels * Neutralize the effect of lateral forces * Improve passenger comfort The necessary cant in a curve depends on the expected speed of the trains and the radius. However, it may be necessary to select a compromise value at design time, for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amtrak
The National Railroad Passenger Corporation, doing business as Amtrak () , is the national passenger railroad company of the United States. It operates inter-city rail service in 46 of the 48 contiguous U.S. States and nine cities in Canada. ''Amtrak'' is a portmanteau of the words ''America'' and ''trak'', the latter itself a sensational spelling of ''track''. Founded in 1971 as a quasi-public corporation to operate many U.S. passenger rail routes, Amtrak receives a combination of state and federal subsidies but is managed as a for-profit organization. The United States federal government, through the Secretary of Transportation, owns all the company's issued and outstanding preferred stock. Amtrak's headquarters is located one block west of Union Station in Washington, D.C. Amtrak serves more than 500 destinations in 46 states and three Canadian provinces, operating more than 300 trains daily over of track. Amtrak owns approximately of this track and operates an addi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NJ Transit
New Jersey Transit Corporation, branded as NJ Transit, and often shortened to NJT, is a state-owned public transportation system that serves the U.S. state of New Jersey, along with portions of New York State and Pennsylvania. It operates bus, light rail, and commuter rail services throughout the state, connecting to major commercial and employment centers both within the state and in the adjacent major cities of New York and Philadelphia. In , the system had a ridership of . Covering a service area of , NJT is the largest statewide public transit system and the third-largest provider of bus, rail, and light rail transit by ridership in the United States. NJT also acts as a purchasing agency for many private operators in the state; in particular, buses to serve routes not served by the transit agency. History NJT was founded on July 17, 1979, an offspring of the New Jersey Department of Transportation (NJDOT), mandated by the state government to address many then-pressi ...

Interoperability
Interoperability is a characteristic of a product or system to work with other products or systems. While the term was initially defined for information technology or systems engineering services to allow for information exchange, a broader definition takes into account social, political, and organizational factors that impact system-to-system performance. Types of interoperability include syntactic interoperability, where two systems can communicate with each other, and cross-domain interoperability, where multiple organizations work together and exchange information. Types If two or more systems use common data formats and communication protocols and are capable of communicating with each other, they exhibit ''syntactic interoperability''. XML and SQL are examples of common data formats and protocols. Lower-level data formats also contribute to syntactic interoperability, ensuring that alphabetical characters are stored in the same ASCII or a Unicode format in all the comm ...

Loading Gauge
A loading gauge is a diagram or physical structure that defines the maximum height and width dimensions in railway vehicles and their loads. Their purpose is to ensure that rail vehicles can pass safely through tunnels and under bridges, and keep clear of platforms, trackside buildings and structures. Classification systems vary between different countries, and gauges may vary across a network, even if the track gauge is uniform. The term loading gauge can also be applied to the maximum size of road vehicles in relation to tunnels, overpasses and bridges, and doors into automobile repair shops, bus garages, filling stations, residential garages, multi-storey car parks and warehouses. A related but separate gauge is the structure gauge, which sets limits to the extent that bridges, tunnels and other infrastructure can encroach on rail vehicles. The difference between these two gauges is called the clearance. The specified amount of clearance makes allowance for wobbling o ...

Stadler GTW
The Stadler GTW is an articulated railcar for local transport made by Stadler Rail of Switzerland. GTW stands for Gelenktriebwagen (articulated railcar). History The Biel–Täuffelen–Ins-Bahn near Bern, Switzerland was looking for a lighter train model to replace its aging fleet, so that a low floor system does not require heavy installations on the roof. Based on that requirement Stadler came up with a concept of placing most of the equipment in a central unit between the seating cars. While the BTI-Bahn tracks are meter gauge, Stadler presented the first prototype in 1995 set on standard gauge rails, and the Mittelthurgau-Bahn tested three prototypes on its standard gauge network during 1996. The rolling stock for Mittelthurgau was later expanded to 10 GTW 2/6 (built 1998–1999) that are now part of the THURBO fleet (the three prototypes were sold to Italy). The next lots were produced in meter gauge, and were delivered to the BTI-Bahn and the CEV-Bahn (Chemins de fer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dwell Time (transportation)
In transportation, dwell time or terminal dwell time refers to the time a vehicle such as a public transit bus or train spends at a scheduled stop without moving. Typically, this time is spent boarding or deboarding passengers, but it may also be spent waiting for traffic ahead to clear, trying to merge into parallel traffic, or idling time in order to get back on schedule. Dwell time is one common measure of efficiency in public transport, with shorter dwell times being universally desirable. Rail systems Dwell times are particularly important for a rail system. Rail headways increase where the dwell times are high. Dwell times are an important focus for rail systems; a reduction in a dwell time can often result in a reduced headway. Passengers who want to board and alight from a train need time to do so. Almost always passengers disembark first, and then passengers waiting on a platform board. A variety of different factors determine how long this takes, including the size of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
