A drive system for a traction vehicle equipped with a current collector, the drive system comprising an electric traction motor, a traction inverter, a traction battery pack, a charger for the battery pack, a coupling member, a current filter, a brake resistor, a brake inverter, a current collector, a electromagnetic interference filter, and a main circuit breaker, the electric traction motor being connected to the traction inverter and the brake resistor being connected to the brake inverter. The drive system further includes a DC rated intermediate circuit being in connection with the main circuit breaker, the brake inverter and the traction inverter on the one hand and with the traction battery pack on the other hand, the latter being connected to said intermediate circuit through an antiparallel combination consisting of the coupling member and the traction battery charger and further through the current filter, said coupling member being composed of a simple power diode.
