![]() Maglev vehicles have set several speed records, and maglev trains can accelerate and decelerate much faster than conventional trains the only practical limitation is the safety and comfort of the passengers, although wind resistance at very high speeds can cause running costs that are four to five times that of conventional high-speed rail (such as the Tokaido Shinkansen). Maglev trains can therefore in some cases be quieter and smoother than conventional trains and have the potential for much higher speeds. This compares with electric multiple units that may have several dozen parts per bogie. While the propulsion and levitation require no moving parts, the bogies can move in relation to the main body of the vehicle and some technologies require support by retractable wheels at low speeds under 150 kilometres per hour (93 mph). With maglev technology, the train travels along a guideway of electromagnets which control the train's stability and speed. ![]() The Shanghai maglev train is the only maglev train in commercial operation that can be considered as high speed. There are both high-speed, intercity maglev systems (over 400 kilometres per hour or 250 miles per hour), and low-speed, urban maglev systems (80–200 kilometres per hour or 50–124 miles per hour) under development and being built. Such trains rise approximately 10 centimetres (4 in) off the track. Maglev (derived from magnetic levitation) is a system of train transportation that uses two sets of electromagnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction.
