Abstract
A railway well car for the transport of containers has a depressed floor section supported between lateral side structures and longitudinal end structures. Each end structure is supported on a frameless radial truck. The frameless radial truck has four longitudinally spaced resilient support elements on each lateral side thereof. The end structure has a reinforcement structure for transferring loads from the car body to the support elements. The reinforcement structure includes a pair of transverse beams extending from a stub center sill to respective side structures. Longitudinal beams extend from the transverse beams to an end sill structure and to a girder structure at the end of the well portion of the car. Each longitudinal beam supports a pair of box structure truck engagement means engaging the resilient support elements. The transverse beams and the longitudinal beams are comprised of channel members attached to the undersurface of a shear plate forming tubular torque box structures therewith. At the end of the well portion diagonally extending support members and tapered plates efficiently beam loads in the side structures to the reinforcement structure and to the truck.
