The TGV (French: ⓘ; train à grande vitesse, [tʁɛ̃ a ɡʁɑ̃d vitɛs] ⓘ, 'high-speed train') [a] is France's intercity high-speed rail service. With commercial operating speeds of up to 320 km/h (200 mph) on the newer lines, [1] 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 ...
This experimental Turbotrain TGV 001 set the world speed record for gas turbine-powered rail vehicles with 318 km/h (198 mph) on 8 December 1972. This TGV 001 was a five-car trainset which possessed four gas-turbine engines with a total output of 6,500 hp (4,800 kW) and all axles motored. [3]
TGV 001 at Bordeaux-Saint-Jean station T 001 seen from the A4 motorway in Bischheim. The TGV 001 (Train à Grande Vitesse 001) was an experimental gas turbine-powered TGV prototype built by Alstom in France. Commissioned in 1969, began testing in 1972 and reached speeds between 250–300 kilometres per hour (160–190 mph).
The final digits uniquely identify the engine within its class, but in the case of a three digit class number, the engine number may begin adding to the class number (for example, a Class 22200 may have a number beginning 222, 223 or 224). Multiple units are numbered the same as locomotives, but prefixed by X for DMUs or Z for EMUs.
The TGV 001 was an experimental gas turbine-electric locomotive-powered trainset built by Alstom to break speed records between 250–300 kilometres per hour.It was the first TGV prototype and was commissioned in 1969, to begin testing in 1972.
An L0 Series trainset, holding the non-conventional train world speed record of 603 km/h (375 mph) TGV 4402 (operation V150) reaching 574.8 km/h (357 mph). The world record for a conventional wheeled passenger train is held by a modified French TGV high-speed (with standard equipment) code named V150, set in 2007 when it reached 574.8 km/h (357.2 mph) on a 140 km (87 mi) section of LGV Est ...
Over 600 sensors were fitted on various parts of both the engines and the cars. The train set ran with larger wheels with a diameter of 1,092 mm (43.0 in) instead of 920 mm (36.2 in), to limit the rotational speed of the powertrain.

The rotating shaft of the motor was also the axle for the wheels. In the case of French TGV power cars, a motor mounted to the power car's frame drives each axle; a "tripod" drive allows a small amount of flexibility in the drive train allowing the trucks bogies to pivot. By mounting the relatively heavy traction motor directly to the power car ...
