Abstract
A magnetic traction assembly is disclosed for a railcar mover that provides additional downforce to improve traction for a railcar mover when required. The magnetic traction assembly may comprise a frame, an actuator, and a magnetic element positioned underneath a railcar mover. The magnetic element may be lowered to a deployed position, where the magnetic element is positioned near the railroad rails such that the magnetic field from the magnetic element interacts with the railroad rail creating an attraction force that provides additional downforce to the railcar mover.
