Electrodynamic Suspension Japanese engineers are developing a competing version of maglev trains that use an electrodynamic suspension EDS system, which is based on the repelling force of magnets and not the attracting force. The key difference between Japanese and German maglev trains is that the Japanese trains use super-cooled superconducting electromagnets.
Development[ edit ] In the late s, the British electrical engineer Eric Laithwaitea professor at Imperial College Londondeveloped the first full-size working model of the linear induction motor.
He became professor of heavy electrical engineering at Imperial College inwhere he continued his successful development of the linear motor.
Laithwaite joined one such project, the Tracked Hovercraftalthough the project was cancelled in In the early s, Laithwaite discovered a new arrangement of magnets, the magnetic riverthat allowed a single linear motor to produce both lift and forward thrust, allowing a maglev system to be built with a single set of magnets.
Working at the British Rail Research Division in Derbyalong with teams at several civil engineering firms, the "transverse-flux" system was developed into a working system.
The system was closed in due to reliability problems. The inventor was awarded U. Patent14 February and U. Patent RE12, 21 August Patent 3,"Magnetic system of transportation", by G. Polgreen 25 August The first use of "maglev" in a United States patent was in "Magnetic levitation guidance system"  by Canadian Patents and Development Limited.
Interest was sufficient that operations were extended three months after the exhibition finished, having carried more than 50, passengers. It was reassembled in Kassel in One of the original cars is now on display at Railworld in Peterborough, together with the RTV31 hover train vehicle.
Another is on display at the National Railway Museum in York. Several favourable conditions existed when the link was built: The British Rail Research vehicle was 3 tonnes and extension to the 8 tonne vehicle was easy.
Electrical power was available. The airport and rail buildings were suitable for terminal platforms. Only one crossing over a public road was required and no steep gradients were involved. Land was owned by the railway or airport. Local industries and councils were supportive.
Some government finance was provided and because of sharing work, the cost per organization was low. After the system closed inthe original guideway lay dormant  untilwhen a replacement cable-hauled system, the AirRail Link Cable Liner people moverwas opened.
However, there is a new form of transportation that could revolutionize transportation of the 21st century the way airplanes did in the 20th century. A few countries are using powerful electromagnets to develop high-speed trains, called maglev trains. Magnetically levitated ground transportation, or "maglev," is an advanced mode of surface high speed transportation whereby a vehicle gliding above a guide track . SwissRapide: The SwissRapide AG in co-operation with the SwissRapide Consortium are developing and promoting an above-ground maglev monorail system, based on the Transrapid technology. The first projects planned are the lines Berne – Zurich, Lausanne – Geneva as well as Zurich – Winterthur.
Emsland test facility Transrapid, a German maglev company, had a test track in Emsland with a total length of Paying passengers were carried as part of the testing process. The construction of the test facility began in and finished in Inthe Lathen maglev train accident occurred killing 23 people, found to have been caused by human error in implementing safety checks.
From no passengers were carried. At the end of the operation licence expired and was not renewed, and in early demolition permission was given for its facilities, including the track and factory. Japan operates two independently developed maglev trains.
The development of the latter started in After an accident that destroyed the train, a new design was selected. Development of HSST started in It was removed after the fair and debut at the Aoi Expo in and now on static display at Okazaki Minami Park.
Berlin, Germany, —91[ edit ] Main article: It was a driverless maglev system with a 1.In the US, the Federal Transit Administration (FTA) Urban Maglev Technology Demonstration program has funded the design of several low-speed urban maglev demonstration projects.
It has assessed HSST for the Maryland Department of Transportation and maglev technology for the Colorado Department of Transportation. The investigation of magnetically levitated systems as a means of ground transportation has been going on for several decades. As a result several methods of control for these systems have been.
However, there is a new form of transportation that could revolutionize transportation of the 21st century the way airplanes did in the 20th century. A few countries are using powerful electromagnets to develop high-speed trains, called maglev trains.
This study was undertaken to (1) evaluate the potential contribution of high-temperature superconductors (HTSCs) to the technical and economic feasibility of magnetically levitated (maglev) vehicles, (2) determine the status of maglev transportation research in the United States and abroad, (3.
speed magnetically levitated ground transportation (maglev) is a new surface mode of transportation, in which vehicles glide above their guideways, suspended, guided, and propelled by magnetic forces.
