Union Pacific O Gauge RailKing Hopper Car w/Operating Coal Load

This unique operating hopper features a "disappearing" coal load that simulates the dumping of coal through the hopper's bottom bay doors. With the car sitting on any manufacturer's 3-rail operating track section (such as an M.T.H. RealTraxr 40-1008), press the activation button and watch the coal sink into the bottom of the car.
