ABSTRACT:
A drop center railway car is provided with a continuous center sill having a depressed portion between the wheel assemblies. The continuous center sill is disposed between a pair of light weight side walls which include side sills that are connected to transverse bolsters for proportionally distributing longitudinal and vertical loads between the two walls and the continuous center sill with the center sill supporting about three-quarters of the longitudinal load. Crossbearers cooperate with the bolsters to prevent injurious bowing of the commodity confining surfaces of the light weight side walls, side sills and bolsters, which light weight is made possible by the forces being proportionally distributed between the three, rather than two, longitudinal members. The drop center portion of the center sill is secured within a flat bottom portion of the car body thus lowering the lowermost cargo supporting surface the maximum amount permitted by government regulations thereby providing a very low center of gravity to the car.
