How do Magnetic trains work?

Magnetic trains work on the principle of magnetic levitation, which is a way of lifting objects by using the forces that keep magnets apart. This makes the train float above their tracks.

 The magnetic train carries powerful linear motors which push against magnets laid in the special track. The magnets in the track first attract the train, pulling it forward and then, when magnetic fields is reserved. repelling the train and pushing it forward even faster. The train and the track do not touch each other. There are no moving parts, such as wheels and, hence, there is no friction between the train and the track.
