TGV inOui

The TGV is the generic name of the trainsets used for the intercity high-speed rail service run by France's national rail operator, SNCF Voyageurs. It is also a quasi-generic initialism for high-speed trains in French, even when not operated by SNCF Voyageurs. With commercial operating speeds of up to 320 km/h (200 mph) on the newer lines, the TGV was conceived at the same period as other technological projects such as the Ariane 1 rocket and Concorde supersonic airliner; sponsored by the Government of France, those funding programmes were known as champion national policies. In 2025, the TGV network in France carried 168 million passengers.
