The French TGV (train à grande vitesse, literally "high speed train") set a new conventional rail record with a speed of 574.8 km/h on 3 April 2007, surpassing the previous record from 1990 of 515.3 km/h. The train was a special TGV named "V150" (for 150 metres/sec, approximately 540 km/h) with "survitiminisé" engines of 25,000 hp (the equivalent of two F1 starting grids), and larger wheels.
This was a test run, in order to enable the trains to run at 360+ km/h in commercial services.
