Maglev trains are trains which are suspended, guided and propelled (moved forward) by magnetic forces. The track of the maglev train is called the guide-way. Working of the maglev trains can be studied under the following. 1  Levitation. 2  Propulsion. 3  Guidance.
The maglev trains are even faster than Japan's famous bullet trains, which currently travel at about 320km/h (200mph). They use magnetic levitation, hence the name, to float above the train tracks. This minimises the friction encountered by ordinary trains, and allows them to travel faster.
