the trains are powered by asynchronous traction motors. there are four powered axles in each power car and two powered axles in the outer bogie of the front passenger coach (a layout used on the original sncf tgv sud-est (pse) sets) giving 12 powered axles. each set draws up to 16mw with 12 mw (16,000 hp) of traction power, but the lowest power-to-weight ratio in the tgv family.
