A TGV test train set the world record for the fastest conventional wheeled train on 3 April 2007. It reached the speed of 574.8 km/h (357.2 m/h) on the test run. But the regular TGV trains operate at the highest speed of 320 km/h (200m/h). It is the present world record of speed of a conventional commercial train.

The Bullet Train is the network of high-speed train service in Japan. It started operation in 1964 on a limited route. But at present, most major cities of Japan come under the network. The Bullet Train runs at a maximum speed of 300 km/h (186m/h). It plans to increase speeds up to 320km/h (200mph). In 2003, Japan set the world record for unconventional magnetic train sets. In a test run, the speed was 581 km/h (361 mph). But it is not yet in regular commercial operation.
