ABSTRACT:
In accordance with the present invention an open top railway car is provided in which the car body is divided longitudinally into at least two body sections having opposite ends which are pivotally mounted on vertically extending supports attached to a car underframe. The body sections include respective transversely spaced side walls, at least one end wall, and bottom walls having inner edges which abut and/or overlap in closed position to define the bottom of the car. To achieve increased volumetric carrying capacity, the bottoms are horizontal and extend outboard of the wheels. Each of the body sections is pivotable from the closed position to an open position in which the inner edges of the bottom walls are spaced apart to allow discharge of lading between the rails. An energy saving unloading system is also disclosed for unloading the cars.
