Shanghai Maglev train (磁悬浮列车)

How it works

A maglev train floats about 10mm above the guidway on a magnetic field. It is propelled by the guidway itself rather than an onboard engine by changing magnetic fields (see right). Once the train is pulled into the next section the magnetism switches so that the train is pulled on again. The Electro-magnets run the length of the guideway.

Shangha Maglev runs at top speed of 250 mph
