Abstract: A speed control system for a railcar mover where the speed control system prevents the railcar mover from exceeding a predetermined maximum vehicle speed. The speed control system determines a target engine speed that overrides a user's throttle control input to keep the railcar mover from exceeding the predetermined maximum vehicle speed. The speed control system also determines a target throttle control position and disables the throttle control from the user until the user moves the throttle control to a position at or less than the target throttle control position.

Abstract: An auxiliary drive axle assembly is disclosed for a railcar mover that provides traction for a railcar mover when required. The auxiliary drive axle assembly comprises a frame, a plurality of hydraulic motors, and a plurality of wheel assemblies positioned underneath a railcar mover. The auxiliary drive axle assembly may be lowered to a use position where the wheels engage the rails either upon demand by the railcar mover operator or automatically by a control system based upon a set of monitored parameters. When in a use position, the control system directs the power to the hydraulic motors such that the wheel assemblies can have optimal traction to assist the railcar mover.
