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.
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.
The Shanghai Maglev track (guideway) was built by local Chinese companies who, as a result of the alluvial soil conditions of the Pudong area, had to deviate from the original track design of one supporting column every 50 meters (160 ft) to one column every 25 meters (82 ft), to ensure that the guideway meets the stability and precision criteria.
Old Dominion University maglev: In 1999, Old Dominion University agreed to work with American Maglev of Atlanta to construct an on-campus student transportation link of less than 1-mile (1.6 km) — using a smart train / dumb track design in which most sensors, magnets, and computation were located on the train rather than the track.

Too tight a 'crest' curve could result in the train leaving the track as it drops away beneath it; too tight a 'trough' and the train will plough downwards into the rails and damage them. More precisely, the support force R exerted by the track on a train as a function of the curve radius r, the train mass m, and the speed v, is given by

Except the Shanghai maglev train and the Pujiang Line, the other seventeen lines (737 km (458.0 mi)) of the Shanghai Metro [3] are all heavy rails. These lines are operated by Shanghai Shentong Metro Group Co., Ltd. , except the Huaqiao section of Line 11 , which is operated by Kunshan Rail Transit Co., Ltd.
