Abstract
A hopper car is converted to a gondola-type car by replacing the hoppers and their dump doors with a light metal sheet floor. The floor sheets form a series of box-like compartments. The compartments are formed by crossbearer partitions extending between the side walls, center sill and the sheet floor. Floor frame members reinforce the rigidity of the floor structure. The partitions are formed by tubular crossbearers on gussets on the center sill, and closure walls converging at the top thereof.
