ABSTRACT OF THE DISCLOSURE A drive for a track-bound propulsion vehicle includes a traction motor with output shafts on both sides. The motor is longitudinally arranged between two driving axles of a track-bound propulsion vehicle and is designed without a housing. In addition, the drive pinions are arranged directly on the rotor shaft which is supported in bearings in the transmission housing which also supports the stator of the traction motor. To take up the thermal expansion due to the different temperature rise of the stator and the rotor, at least one centering coupling which permits longitudinal displacement is provided in the train of the rotor shaft.
