The French high-speed train V150 reached 574.8 km/h during a 2007 world rail-speed record attempt.
V150 was a specially modified TGV train operated by SNCF and Alstom on 3 April 2007. The test ran on the newly built LGV Est high-speed line between Paris and Strasbourg. Its name referred to the target speed of 150 metres per second, approximately 540 km/h.
The train used three double-decker power cars and two specially adapted TGV Duplex intermediate cars. Larger wheels, increased electrical power and aerodynamic modifications helped it exceed the target. The record was achieved under controlled test conditions rather than normal passenger service.
V150 is often confused with Japan’s L0 Series maglev, which later recorded a higher speed, or with ordinary TGV service trains. V150’s 574.8 km/h remains a conventional steel-wheel-on-steel-rail record, not a maglev record.
