Determination of the fastest rail vehicle in the world varies depending on the definition of "rail".
The French TGV (Train à Grande Vitesse) is the fastest conventional train in the world, using powered metal wheels riding on metal rails. In April 2007, the TGV broke its own 1990 record with a new speed of 574.8 km/h (357.18 mph) under test conditions with a shortened train (two power cars and three passenger cars) and larger wheels to reduce angular speed in the motors.
The Japanese JR-Maglev is the fastest non-conventional train in the world, having achieved 581 km/h (361 mph) on a magnetic-levitation track. Unmanned rocket sleds that ride on rails have reached over 10,400 km/h (6,462 mph), equivalent to Mach 8.5. The fastest manned rail vehicle is a manned rocket sled, that travelled at 1,017 km/h (635 mph).
