The maglev (magnetic levitation) train was invented by Americans James R. Powell and Gordon T. Danby. Hermann Kemper, Robert Goddard and Emile Bachelet are also credited with important research and development that lead to this invention.
A maglev train operates by using the basic principles of opposing magnetic forces to enable a train to "float" above the track it travels along. Magnetic levitation provides a frictionless form of propulsion for a train, allowing speeds in excess of 350 mph to be achieved. Robert Goddard and Emile Bachelet came up with the first concept for a maglev train in the early 1900s, and more work in this field was conducted in the 1930s by the German inventor Hermann Kemper.
