Maglev trains use powerful electromagnets to hover above tracks

Eliminating mechanical wheel friction allows magnetic levitation trains to exceed six hundred kilometres per hour

Magnetic levitation trains replace traditional steel wheels and rails with superconducting electromagnets that levitate the train cars several millimetres above a guideway. Eliminating mechanical friction and rolling resistance permits smooth acceleration and high top speeds. Japan's L0 Series Maglev holds the world rail speed record at 603 kilometres per hour.
