Abstract: An apparatus that can be affixed to a standard railcar thereby converting a standard railcar into a self-propelled railcar, such self-propelled railcar having the capacity to move independently and serve as a locomotive for moving other railcars. The apparatus includes a railcar drive assembly that can be retrofitted to a railcar in such a manner that the hydraulic motor, hoses, and connectors of the drive assembly motor mechanism are positioned below the bed of the railway car and between the drive assembly housing and the railway car's wheel-and-truck assembly. This drive assembly design ensures that the drive assembly motor mechanism's hydraulic motor, hoses, and connectors are protected from general railway track debris as well as obstructions in the railroad right of way, and helps prevent unnecessary damage or the need for untimely maintenance.
