Abstract: A ballast discharge car having at least one non-pivoting transverse conveyor disposed beneath a hopper for distributing the ballast between the rails, near the outside of the rails, and well beyond the outside of the rails in a stockpiling application. The speed, direction, and angle of each conveyor is adjustable so that the ballast can be selectively cast a wide range of distances from the outside of the rails.
