Abstract: A lightweight structural hopper car unit is provided utilizing a through sill, a bolster cover plate and side sills. Approximately 70% of the longitudinal squeeze loads are carried by the through sill and about 15% by each of the side sills. Thus the thickness of the sides and side sills can be reduced, and diagonal stiffeners utilized in the end structure of prior constructions can be eliminated.
