Transrapid 09 at the Emsland test facility in Lower Saxony, Germany A full trip on the Shanghai Transrapid maglev train Example of low-speed urban maglev system, Linimo. 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.
' Shanghai Maglev Demonstration Operation Line ') is a magnetic levitation train (maglev) line that operates in Shanghai, China. The line uses the German Transrapid technology. [ 2 ] The Shanghai maglev is the world's first commercial high-speed maglev and has a maximum cruising speed of 300 km/h (186 mph). [ 3 ]
The super-speed Transrapid maglev system has no wheels, no axles, no gear transmissions, no steel rails, and no overhead electrical pantographs.The maglev vehicles do not roll on wheels; rather, they hover above the track guideway, using the attractive magnetic force between two linear arrays of electromagnetic coils—one side of the coil on the vehicle, the other side in the track guideway ...
L0 Series maglev train at Yamanashi test track. The SCMaglev (superconducting maglev, formerly called the MLU) is a magnetic levitation railway system developed by Central Japan Railway Company (JR Central) and the Railway Technical Research Institute.
A vactrain (or vacuum tube train) is a proposed design for very-high-speed rail transportation. It is a maglev (magnetic levitation) line using partly evacuated tubes or tunnels. Reduced air resistance could permit vactrains to travel at very high ( hypersonic ) speeds with relatively little power—up to 6,400–8,000 km/h (4,000–5,000 mph).
Maglev trains are promoted for their energy efficiency since they run on electricity, which can be produced by coal, nuclear, hydro, fusion, wind or solar power without requiring oil. [4] On average most trains travel 483 km/h (300 mph) and use 0.4 megajoules per passenger mile. [ 10 ]
If not deployed in an evacuated tube the power needed for levitation is usually not a particularly large percentage and most of the power needed is used to overcome air drag, as with any other high speed train. Some maglev Hyperloop prototype vehicles are being developed as part of the Hyperloop pod competition in 2015–2016, and are expected ...
Since a maglev requires a guiding rail, it is mostly used in railed transport systems like trains. Since the first commercial maglev train was opened in Birmingham, England in 1984, other commercial EMS maglev train systems, such as the M-Bahn and the Transrapid have also been put into limited use.
