The TGV Atlantique is the second generation of TGV high-speed trains used in France, built between 1988 and 1992 following on from the TGV Sud-Est. 105 trainsets were built for the opening of the LGV Atlantique line. The Atlantique is made up of two power cars and ten carriages with a total of 485 seats and capable of a maximum speed of 300 km/h (186 mph).
Modified unit 325 set the world speed record in 1990 on the new LGV before its opening. Modifications, such as improved aerodynamics, larger wheels and improved braking were made to enable test run speeds of over 500 km/h (311 mph). The set was reduced to two power cars and three carriages to improve the power-to-weight ratio, weighing 250 t (246 long tons; 276 short tons). The TGV Atlantique’s world record was beaten on the 3 April 2007, by a TGV POS set on the LGV Est, which reached a top speed of 574.8 km/h (357.2 mph).
