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.

A power system for short trains. In an embodiment, an over-the-road tractor is configured with drive gears on a drive axle to interface with driven gear systems on a rail car. By utilizing the apparatus, a method for efficient delivery of goods in containers on semi-trailers may be achieved, thus saving considerable time, and reducing costs.

An adjustable roller assembly for a linear rail system carriage has an indexing collar, an eccentric bushing, an adjustable roller, a suspension element, and an adjustment collar. The indexing collar has a first indexing structure. The adjustable roller is rollably mounted to a roller side end of the eccentric bushing. A rolling axis of the adjustable roller is offset from the axis of the adjustable roller assembly. The suspension element is mounted in axial alignment with an adjustment side end of the eccentric bushing. The adjustment collar has a circumferential flange having a second indexing structure. The first indexing structure and the second indexing structure are coupled to rotationally couple the adjustment collar with the suspension element.
