Abstract
A railway tank car including a protective structure for the top of its cargo tank and surrounding both a valve group mounting nozzle and a pressure-relief safety valve nozzle, to protect the associated valves against damage resulting from the car being overturned, particularly while the railcar is moving along a railway. The protective structure includes protective housings including upstanding walls of metal plate construction surrounding the nozzles yet not attached directly to the nozzles, so that the protective housings afford convenient access to the valves associated with the nozzles.
