Shanghai, China had a big problem moving people between two city airports. The trip was only 20 miles long but would sometimes take 6 hours to make. The city also had a terrible pollution problem. This city turned to a new type of train to help with their problem: Magnetic Levitation Propulsion or maglev.
The train does not use wheels to move! It uses the power of magnets. The train floats above a giant magnet which pushes it along.
This train can travel 431 miles per hour
