Abstract
A gondola car has a body for lading carried on an underframe. The underframe includes a center sill and cross-bearers. The car has deep side beams having top chords, side sills, and side sheets. The lower portion of the car includes tubs that seat between the cross-bearers. The car may have an internal volume of more than 8000 cu. ft. The car may have rotary dump claw sockets. The car has opposed internal and external stiffeners aligned at the longitudinal stations of the cross-bearers. The internal stiffeners may be triangular cantilevers extending upwardly inside the side sheets. The side sheet lies intermediate the stiffeners and their flanges. The top chords may be wider in cross-section than the side sills. The side sills may define torque tubes that co-operate with the sidewall stiffeners and the top chords to resist lateral deflection. The car may include a false deck, or dog-house at one end to accommodate the brake reservoir and brake valve, such that the car is longitudinally asymmetric.
