ABSTRACT:
A rotary dump railway gondola car that includes troughs which extend downwardly from the midpoint of the car toward the trucks. End members for the troughs extend at an enlarged angle relative to the car's center sill to increase the carrying capacity of the car. The end members have been further modified to include a bracket which attaches each end member to the center sill. A chamfer is located near the lower portion of each end member to allow drainage from the associated trough. Sections of the floor in the car adjacent to the troughs have been modified to increase load carrying capacity. The troughs may also include a longitudinal radius to further increase the load carrying capacity of the car.
