Abstract
A rotary dump gondola railway car that includes troughs which extend angularly from the centerline of the car toward the trucks and thereby lower the center of gravity of the car, increase the capacity of the car, or provide the same capacity with lowered overall height, thereby reducing the wind resistance or drag of the car and providing more efficient operation.
