ABSTRACT OF THE DISCLOSURE: A motor-driven rail-vehicle with a drive system includ- ing an electric motor and drive wheels is provided with an oscil- lation sensing member which senses oscillations within a pre- determined frequency range of an electrical quantity of the drive system, such as the armature current or voltage, and forms a signal representing such oscillations. This signal is compared with a signal corresponding to a predetermined threshold value, and the tractive force of the motor is reduced in response to an increase of the oscillation amplitude above such threshold value.
