An electrical propulsion system for a traction vehicle adapted to haul a payload, the vehicle being equipped with weight sensing means for distinguishing between loaded and unloaded conditions and with communication means adapted to receive from an.external source a coded signal indicative of a given speed limit, the system including electric motors driving a pair of vehicle wheels, a controllable source of electric power for the motors, means for switching from propulsion to electrical retarding modes of operation in response to the actual speed of the vehicle becoming greater than a desired maximum, and means connected to the weight sensing means and to the communication means for automatically adjusting the maximum propulsion speed so that it is lower when said loaded condition is true than when said unloaded condition is true and for automatically changing the maximum propulsion speed as necessary to avoid exceeding the limit indicated by said coded signal.
