The first commercial high speed services in France commenced with the TGV Sud-Est between Paris and Lyon in 1981. The abbreviation TGV stands for “Train à Grande Vitesse” or just “High Speed Train”. In contrast to the gas turbine powered TGV 001 prototype, the production train was electrically powered. Each set consisted of two power cars and eight trailer cars which were connected by Jacobs bogies. In the first generation, one bogie of the first and last trailers was also powered. This made a total of twelve traction motors with an hourly output of 537.5 kW each, giving a total of 6,450 kW.
