The SNCF's TGV has set many world speed records, the most recent on 3 April 2007, when a new version of the TGV dubbed the V150 with larger wheels than the usual TGV, was able to cover more ground with each rotation and had a stronger 25,000 hp (18,600 kW) engine, and broke the world speed record for conventional railway trains, reaching 574 kmph .
