Maglev is short for Magnetic Levitation. Hence, the train is using magnetism to reduce friction. By having magnets on the track be opposed to magnets on the bottom of the train, the magnetic repulsion keeps the train levitating slightly above the tracks. This means that train is essentially riding on air, which has way less friction than a wheel on a metal track.
