MagRail
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. Differ ...

Transrapid 09
Transrapid () is a German-developed High-speed rail, high-speed monorail, monorail train using Maglev, magnetic levitation. Planning for the system started in the late 1960s, with Emsland test facility, 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 Lathen train collision, Transrapid train collided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrodynamic Suspension
Electrodynamic suspension (EDS) is a form of magnetic levitation in which there are conductors which are exposed to time-varying magnetic fields. This induces eddy currents in the conductors that creates a repulsive magnetic field which holds the two objects apart. These time-varying magnetic fields can be caused by relative motion between two objects. In many cases, one magnetic field is a permanent field, such as a permanent magnet or a superconducting magnet, and the other magnetic field is induced from the changes of the field that occur as the magnet moves relative to a conductor in the other object. Electrodynamic suspension can also occur when an electromagnet driven by an AC electrical source produces the changing magnetic field, in some cases, a linear induction motor generates the field. EDS is used for maglev trains, such as the Japanese SCMaglev. It is also used for some classes of magnetically levitated bearings. Types Many examples of this have been used over th ...

Air-Rail Link
The Air-Rail Link is a people mover linking Birmingham Airport with Birmingham International railway station and the National Exhibition Centre in England. The current system, originally known as SkyRail, replaced the earlier Birmingham Maglev system in 2003. The current system is a fully automated cable-hauled system. It takes passengers between the high-level railway station concourse and the airport terminal buildings, covering a distance of . It is free to use, and handles three million passengers per year. At off-peak times, the system operates on demand using call buttons. The Air-Rail Link was constructed between 2001 and 2003 using the Cable Liner technology from Doppelmayr Cable Car; it was the firm's first airport system. The Birmingham Maglev, opened in 1984, was the first commercial Maglev transport system in the world. Constructed during the early 1980s by a consortium under contract from West Midlands County Council, the system was fully automated and used an eleva ...

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] |
Derby
Derby ( ) is a City status in the United Kingdom, city and Unitary authorities of England, unitary authority area on the River Derwent, Derbyshire, River Derwent in Derbyshire, England. Derbyshire is named after Derby, which was its original county town. As a unitary authority, Derby is administratively independent from Derbyshire County Council. The population of Derby is (). The Romans established the town of Derventio Coritanorum, Derventio, which was later captured by the Anglo-Saxons and then by the Vikings who made one of the Five Boroughs of the Danelaw. Initially a market town, Derby grew rapidly in the industrial era and was home to Lombe's Mill, an early British factory and it contains the southern part of the Derwent Valley Mills World Heritage Site. With the arrival of the railways in the 19th century, Derby became a centre of the Rail transport in Great Britain, British rail industry. Despite having a Derby Cathedral, cathedral since 1927, Derby did not gain City ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Rail Research Division
The British Rail Research Division was a division of the state-owned railway company British Rail (BR). It was charged with conducting research into improving various aspects of Britain's railways, particularly in the areas of reliability and efficiency, including achieving cost reductions and increasing service levels. Its creation was endorsed by the newly created British Rail Board (BRB) in 1963 and incorporated personnel and existing resources from all over the country, including the LMS Scientific Research Laboratory. It was primarily based at the purpose-built Railway Technical Centre in Derby. In addition to its domestic activities, the Research Division would provide technology and personnel to other countries for varying purposes and periods under the trade name "Transmark". It became recognised as a centre of excellence in its field; the theoretical rigour of its approach to railway engineering superseded the ad hoc methods that had prevailed previously.

Magnetic River
Magnetic river is an electrodynamic suspension, electrodynamic magnetic levitation (maglev) system designed by Fredrick Eastham and Eric Laithwaite in 1974. It consists of a thin conductive plate on an AC linear induction motor. Due to the transverse flux and the geometry, this gives it lift, stability and propulsion as well as being relatively efficient. The name refers to the action that provides stability along the longitudinal axis, which acts similar to the flow of water in a river. Linear motors A linear induction motor (LIM) is essentially a conventional induction motor with its primary "unwound" and laid out flat. The rotor, normally consisting of a series of conductors wound onto a form of some sort, is replaced by a sheet of magnetically susceptible metal. Due to its good conductance to weight ratio, aluminium is almost always used for this "stator plate". When the primaries are fed current, they induce a magnetic field in the stator plate, which generates forces away from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tracked Hovercraft
Tracked Hovercraft was an experimental high-speed train developed in the United Kingdom during the 1960s. It combined two British inventions, the hovercraft and the linear induction motor, in an effort to produce a train system that would provide inter-city service with lowered capital costs compared to other high-speed solutions. Substantially similar to the French Aérotrain and other hovertrain systems of the 1960s, Tracked Hovercraft suffered a fate similar to those of the other projects when it was cancelled as a part of wide budget cuts in 1973. History Genesis at Hovercraft Development It was noticed early on in the development of the hovercraft that the energy needed to lift a vehicle was directly related to the smoothness of the surface on which it travelled. This was not entirely surprising; the air trapped under the hovercraft will remain there except where it leaks out where the lifting surface contacts the groundif this interface is smooth, the amount of leaked ai ...
