The magnetic levitation train is a very long asynchronous linear motor intended for transportation of fragile cargo and people. A conductive train is accelerated by a quickly changing magnetic field produced by stationary coils. Power supply requirements are less demanding than those of a short coilgun. The minimum mass (for 1-ton cargo) is 106 tons.
The only passenger-carrying maglev train in the world links Pudong International Airport in Shanghai, China, to the city center at speeds of 430 kilometers per hour.
