Abstract
A railway tank car including a protective structure for the top of the tank and surrounding a manway or valve mounting nozzle to protect it against damage resulting from the car being overturned even while moving longitudinally. The protective structure may include longitudinally extending generally parallel side plates and a skid structure including longitudinally extending sloping, end portions and providing access to a manway or valve mounting assembly on the top of a nozzle. Openings may be provided in a side wall of the protective structure to give access to valve operating mechanisms extending laterally from valves. A lid for an access opening to a set of valves may include an extension that prevents a valve handle from being moved to open the valve while the lid is closed.
