Monorails In China
A monorail is a railway in which the track consists of a single rail or beam. Colloquially, the term "monorail" is often used to describe any form of elevated rail or people mover. More accurately, the term refers to the style of track.The term "track" is used here for simplicity. Technically the monorail sits on or is suspended from a guideway containing a singular structure. There is an additional generally accepted rule that the support for the car must be narrower than the car. Monorail systems are most frequently implemented in large cities, airports, and theme parks. Etymology The term possibly originated in 1897 from German engineer Eugen Langen, who called an elevated railway system with wagons suspended the '' Eugen Langen One-railed Suspension Tramway'' (Einschieniges Hängebahnsystem Eugen Langen). Differentiation from other transport systems Monorails have found applications in airport transfers and medium capacity metros. To differentiate monorails from other t ...

Linear Induction Motor
A linear induction motor (LIM) is an alternating current (AC), asynchronous linear motor that works by the same general principles as other induction motors but is typically designed to directly produce motion in a straight line. Characteristically, linear induction motors have a finite primary or secondary length, which generates end-effects, whereas a conventional induction motor is arranged in an endless loop. Despite their name, not all linear induction motors produce linear motion; some linear induction motors are employed for generating rotations of large diameters where the use of a continuous primary would be very expensive. As with rotary motors, linear motors frequently run on a three-phase power supply and can support very high speeds. However, there are end-effects that reduce the motor's force, and it is often not possible to fit a gearbox to trade off force and speed. Linear induction motors are thus frequently less energy efficient than normal rotary motors for an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transrapid
Transrapid () is a German-developed high-speed monorail train using magnetic levitation. Planning for the system started in the late 1960s, with a test facility in Emsland, Germany, inaugurated in 1983. In 1991, technical readiness for application was approved by the Deutsche Bundesbahn in cooperation with renowned universities. The last version, the 2007-built Transrapid 09, is designed for a cruising speed of and allows acceleration and deceleration of approximately . In 2002, the first commercial implementation was completed – the Shanghai Maglev Train, which connects the city of Shanghai's rapid transit network to Shanghai Pudong International Airport. The Transrapid system has not yet been deployed on a long-distance intercity line. The system was developed and marketed by Siemens and ThyssenKrupp, as well as other, mostly German companies. In 2006, a Transrapid train collided with a maintenance vehicle on the German test track, leading to 23 fata ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maglev (transport)
Maglev (derived from ''magnetic levitation'') is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance. Compared to conventional railways, maglev trains have higher top speeds, superior acceleration and deceleration, lower maintenance costs, improved gradient handling, and lower noise. However, they are more expensive to build, cannot use existing infrastructure, and use more energy at high speeds. Maglev trains have set several speed records. The train speed record of was set by the experimental Japanese L0 Series maglev in 2015. From 2002 until 2021, the record for the highest operational speed of a passenger train of was held by the Shanghai maglev train, which uses German Transrapid technology. The service connects Shanghai Pudong International Airport and the outskirts of central Pudong, Shanghai. At its historical top speed, it covered the distance of in just over 8minutes. Diffe ...

Elevated Train
An elevated railway or elevated train (also known as an el train or el for short) is a railway with the tracks above street level on a viaduct or other elevated structure (usually constructed from steel, cast iron, concrete, or bricks). The railway may be a broad-gauge, standard-gauge or narrow-gauge railway, light rail, monorail, or a suspension railway. Elevated railways are normally found in urban areas that would otherwise require impracticably many level crossings. Usually, the tracks of elevated railways that run on steel viaducts can be seen from street level. History The earliest elevated railway was the London and Greenwich Railway on a brick viaduct of 878 arches, built between 1836 and 1838. The first of the London and Blackwall Railway (1840) was also built on a viaduct. During the 1840s there were other plans for elevated railways in London that never came to fruition. From the late 1860s onward, elevated railways became popular in US cities. New York's W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantograph (rail)
A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or trolley buses to collect power through contact with an overhead line. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings. The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. Other types of current collectors include the bow collector and the trolley pole. Invention The pantograph, with a low-friction, replaceable graphite contact strip or "shoe" to minimise lateral stress on the contact wire, first appeared in the late 19th century. Early versions include the bow collector, invented in 1889 by Walter Reichel, chief engineer at Siemens & Halske in Germany, and a flat slide-pantograph first used in 1895 by the Baltimore and Ohio Railroad. The familiar diamond-shaped roller pantograph was devised and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...

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] |
Rubber-tyred Metro
A rubber-tyred metro or rubber-tired metro is a form of rapid transit system that uses a mix of road transport, road and rail transport, rail technology. The vehicles have wheels with rubber tires that run on a roll way inside guide bars for traction. Traditional, Flange, flanged steel wheels running on rail tracks provide guidance through Railroad switch, switches and act as backup if tyres fail. Most rubber-tyred trains are purpose-built and designed for the system on which they operate. Guided buses are sometimes referred to as 'trams on tyres', and compared to rubber-tyred metros. History The first idea for rubber-tyred railway vehicles was the work of Scotsman Robert William Thomson, the original inventor of the pneumatic tire, tyre. In his patent of 1846 he describes his 'Aerial Wheels' as being equally suitable for, "the ground or rail or track on which they run". The patent also included a drawing of such a railway, with the weight carried by pneumatic main wheels runnin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tram
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which Rolling stock, vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated Right-of-way (property access), right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term ''light rail'', which also includes systems separated from other traffic. Tram vehicles are usually lighter and shorter than Main line (railway), main line and rapid transit trains. Most trams use electrical power, usually fed by a Pantograph (transport), pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city stre ...
