RAILWAY HOPPER CAR

摘要

A covered railway hopper car includes side walls comprising upper arcuate side sheet and lower flat inclined side sheet portions. The upper edge of the flat side sheet is bent to form a longeron which extends intermediate the height of the side wall and which is attached adjacent the lower edge of the arcuate side wall. A side sill extends longitudinally on the exterior of the flat side sheet to form, together with the longeron, reinforcement for the side walls. The car also includes an end structure comprising a vertical plate extending upwardly into support of the end slope walls of the car at a location intermediate the length of the end slope walls and a vertical support on the interior of the wall above the plate to distribute forces directly from the center plate of the car to the roof at a location spaced from the vertical end walls of the car.
