Abstract
A railway hopper car is disclosed which includes a car body defined by opposite arcuate side sheets having a side sill extending longitudinally along the lower margin of each side sheet and at least a first end slope sheet partially defining an end hopper compartment. An end support structure for the end hopper compartment is secured to the car body and includes a shear plate extending transversely between the side sills, a stub center sill disposed subjacent the shear plate, a bolster beam extending laterally on either side of the stub center sill and interconnecting the stub center sill with the side sill, a vertical bolster web interconnecting the stub center sill and the shear plate, an additional vertical bolster web assembly interconnecting the stub center sill, the shear plate, and the bolster beam, and a plurality of vertical gusset plates interconnecting the slope sheet and shear plate. The gusset plates project perpendicular to the shear plate and are disposed in spaced, parallel relation to each other in an array which extends laterally with respect to the longitudinal axis of the car.
