ABSTRACT:
The disclosure concerns a removable, rigid cover system for railway hopper cars. The system employs a set of welded, steel roof sections which are bolted together end-to-end through upstanding flanges, and which are attached to the car by J-bolts which engage the outturned flanges at the upper margins of the side and end walls of the car. The sections have depending exterior skirts which, in the aggregate, envelope the car and serve to prevent entry of water and to shield the J-bolts from damaging impacts. The section may also have depending interior skirts which act as dams to minimize escape of grain from the car. The system also includes hatchways with hinged covers which facilitate loading of the car, and a walkway.
