Faster than This Speeding Train, Superman?
2, 2003, a magnetically levitated train developed by the Central Japan Railway Company
set a world speed record of 581 km/h (361 mi/h). The train is planned to run a normal
500 km route between Tokyo and Osaka in one hour. Liquid-helium-cooled superconducting
electromagnets are sequentially repelled and attracted by conductive coils in the
track's sidewalls for propulsion. To minimize friction, the entire train is magnetically
levitated above and between the rails. For comparison, the famed American P-40 Warhawk
and British Spitfire of WWII had about the same top speed in level flight.
