Roll Way
__NOTOC__ A roll way or running pad is the pad placed on a concrete slab or on the ties on the outside of the conventional track along both running rails of a rubber-tyred metro or along the unconventional track of a tram. The rubber-tyred wheels roll directly on the roll ways. * With a conventional track: ** The ones of the Montreal Metro are precast concrete on a concrete slab. ** The ones of the Paris Métro are H-steel on ties. ** The ones of the Mexico City Metro are H-steel. ** The ones of the Santiago Metro are precast concrete below ground and H-steel above ground. ** The ones of the Lausanne Métro Line M2 are H-steel. ** The ones of the Lyon Metro (lines A, B and D) are H-steel. * Without a conventional track: ** The ones of the Lille Metro are precast concrete. ** The ones of the Toulouse Metro are precast concrete. **The ones of the Sapporo Municipal Subway are flat steel with a central guide rail. ** Busan Subway Line 4 runs directly on a concrete slab betw ...

Concrete Slab
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel- reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner ''mud slabs'' may be used for exterior paving . In many domestic and industrial buildings, a thick concrete slab supported on foundations or directly on the subsoil, is used to construct the ground floor. These slabs are generally classified as ''ground-bearing'' or ''suspended''. A slab is ground-bearing if it rests directly on the foundation, otherwise the slab is suspended. For multi-story buildings, there are several common slab designs : * Beam and block, also referred to as ''rib and block'', is mostly used in residential and industrial applications. This slab type is made up of pre-stressed beams and hollow blocks and are temporarily propped until set, typically after 21 days. * A hollow core slab which ...

Sapporo Municipal Subway
The is a mostly-underground rubber-tyred rapid transit system in Sapporo, Hokkaido, Japan. Operated by the Sapporo City Transportation Bureau, it is the only subway system on the island of Hokkaido. Lines The system consists of three lines: the green Namboku Line (North–south line), orange Tozai Line (East–west line), and blue Tōhō Line (North East Line). The first, the Namboku Line, was opened in 1971 prior to the 1972 Winter Olympics. The Sapporo City Subway system operates out of two main hubs: Sapporo Station and Odori Station. Most areas of the city are within a reasonable walking distance or short bus ride from one of the subway stations. The three lines all connect at Odori Station. The Namboku Line and Tōhō Line lines connect with the JR Hokkaido main lines at Sapporo Station. At Odori and Susukino stations, it connects to the streetcar (tram) above. The system has a total length of with 46 stations. Except for the section of the Namboku Line south o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bumper Post
A buffer stop, bumper, bumping post, bumper block or stopblock (US), is a device to prevent railway vehicles from going past the end of a physical section of track. The design of the buffer stop is dependent, in part, on the kind of couplings that the railway uses, since the coupling gear is the first part of the vehicle that the buffer stop touches. The term "buffer stop" is of Italian origin, since railways in Italy principally use buffer-and-screw couplings between vehicles. Types Several different types of buffer stop have been developed. They differ depending on the type of coupler used and on the intended application. * Buffer stops with anticlimbers. These are particularly important for passenger railway applications, because the anticlimbers reduce the likelihood of telescoping of the railroad cars during a head-on impact. * Buffer stops for a knuckle coupler or an SA3 coupler (centrally positioned between the two rails) * Buffer stops with traditional " buffers ...

Sand Drag
Catch points and trap points are types of points which act as railway safety devices. Both work by guiding railway carriages and trucks from a dangerous route onto a separate, safer track. Catch points are used to derail vehicles which are out of control (known as ''runaways'') on steep slopes. Trap points are used to protect main railway lines from unauthorised vehicles, moving onto them from sidings or branch lines. Either of these track arrangements may lead the vehicles into a sand drag or safety siding, track arrangements which are used to safely stop them after they have left the main tracks. A derail is another device used for the same purposes as catch and trap points. Trap points ''Trap points'' are found at the exit from a siding or where a secondary track joins a main line. A facing turnout is used to prevent any unauthorised movement that may otherwise obstruct the main line. The trap points also prevent any damage that may be done by a vehicle passing ...

Bombardier Guided Light Transit
Guided Light Transit (GLT, ) was the name of guided bus technology and associated infrastructure manufactured by Bombardier Transportation (now Alstom). Two GLT prototypes were designed and tested from 1987 onwards by BN in the region of Rochefort in Belgium. It was eventually installed in two French cities: Nancy and Caen. The Caen system was closed in 2017 and replaced by conventional trams, while the Nancy system was closed in March 2023 and has been replaced by trolleybuses. Both of the systems in these cities are referred to as " tramways on tyres", and in common with tram systems they use a surface guidance system and in normal operation are powered by electricity drawn from an overhead wire. However, while the vehicles are guided by a central guidance rail, they ride on rubber tyres, not on rails. There has been disagreement about whether they should be called "trams", for that reason and also because they are capable of being steered and operating independently of ...

Translohr
Translohr is the name of a rubber-tyred tramway technology, originally developed by Lohr Industrie of France and now run by a consortium of Alstom Transport and Fonds stratégique d'investissement (FSI) as ''newTL,'' which took over from Lohr in 2012. It is used in Paris and Clermont-Ferrand, France; Medellín, Colombia; and Venice-Mestre and Padua in Italy. In June 2012, Alstom Group and the Strategic Investment Fund acquired Translohr for €35 million. Description The Translohr system is more like a tram or light railway than a bus or trolleybus. Unlike other guided bus systems, including the similar but incompatible Guided Light Transit system developed by Bombardier Transportation, Translohr cars permanently follow guide rails that they cannot divert from, like traditional steel-wheeled rail vehicles. The guide rail automatically guides the vehicle, with a driver who stops and starts, accelerating and braking when needed. Power is provided by overhead wires an ...

Rubber-tyred Trams
A rubber-tyred tram (also known as tramway on tyres, ) is a development of the guided bus in which a vehicle is guided by a fixed rail in the road surface and draws current from overhead electric wires (either via pantograph or trolley poles). Two incompatible systems using physical guide rails exist: the guided light transit (GLT) designed by Bombardier Transportation, and the translohr from Lohr Industrie (currently made by Alstom and FSI). There are no guide bars at the sides but there is a central guidance rail that differs in design between the systems. In the case of Translohr, this rail is grasped by a pair of metal guide wheels set at 45° to the road and at 90° to each other. In the GLT system, a single double-flanged wheel between the rubber tires follows the guidance rail. In both cases, the weight of the vehicle is borne by rubber tires to which the guide wheels are attached, which make contact with the road on concrete roll ways designed to minimise impac ...

Guided Bus
Guided buses are buses capable of being steered by external means, usually on a Bus lane, dedicated track or roll way that excludes other traffic, permitting the maintenance of Public transport timetable, schedules even during rush hours. Unlike railbuses, trolleybuses or rubber-tyred trams, for part of their routes guided buses are able to share road space with general traffic along conventional roads, or with conventional buses on standard bus lanes. Guidance systems can be physical, such as Curb (road), kerbs or guide bars, or Autonomous car, remote, such as optical or radio guidance. A guided buses line can be categorised as bus rapid transit and may be articulated bus and bi-articulated bus, allowing more passengers, but not as many as light rail or trams, which are not constrained to a regulated maximum size in order to freely navigate public roads. History Precursors The kerb-guided bus (KGB) guidance mechanism is a development of the early Wagonway#Plateways, flangew ...

Crystal Mover
The Crystal Mover is a rubber-tired automated people mover (APM) system for airport and urban rail transit applications manufactured at Mitsubishi Heavy Industries (MHI) Mihara Machinery Works in Mihara, Hiroshima Prefecture, Japan. The Crystal Mover, initially based on the Japanese APM standard, is used in automated guideway transit (AGT) systems in China, Japan, Singapore, South Korea, the United Arab Emirates and the United States. Since 2010s MHI has been building and delivering a new family of AGT systems branded Urbanismo as the successor to the Crystal Mover. The Urbanismo family consists of a higher-speed model called "Urbanismo Super AGT" with a top speed of 120 km/h and three customizable models called "Urbanismo-22", "Urbanismo-18", and "Urbanismo-16" with a gross weight of over 22, 18, and 16 tonnes, respectively.

People Mover
A people mover or automated people mover (APM) is a type of small-scale automated guideway transit system. The term is generally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks. The term was originally applied to three different systems, developed roughly at the same time. One was Skybus, an automated mass transit system prototyped by the Westinghouse Electric Corporation beginning in 1964. The second, alternately called the People Mover and Minirail, opened in Montreal at Expo 67. Finally the last, called PeopleMover or WEDway PeopleMover, was an attraction that was originally presented by Goodyear Tire and Rubber Company and that opened at Disneyland in 1967. The term "people mover" currently describes technologies such as monorail, rail tracks and maglev. Propulsion may involve conventional on-board electric motors, linear motors or cable traction. Generally speaking, larger APMs are referred to by oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guide Bar
Guide bars, or guiding bars are rubber-tyred metro systems that incorporate track. They have angle irons as outside of the two roll ways. The Busan Subway Line 4 lacks a rail track, and has I-beams installed as guide bars. The flanges are vertical. The Sapporo Municipal Subway, that lacks a rail track as well, has no guide bars. It has a central guide rail instead. Guide bars are also used to provide guidance for guided buses.
