A gantry adapted for operation along rails attached to the top of a railroad car includes two pairs of wheels, each pair operating on a respective rail. A base support member is positioned above the rail and between the wheels on each side of the gantry. Should one end of the gantry be inadvertently driven off of the rails, the base support members engage the rails to prevent the gantry from toppling off of the railroad car. In addition, a safety rail is positioned inside of and above each rail and a plurality of J-hooks are attached to the inside of each base support member to engage the safety rails and prevent the gantry from tipping from side-to-side. All four wheels are independently driven and the gantry is adapted to support a commercially available crane, the position of which can be vertically adjusted via spacers. A number of other safety features are included.
