ABSTRACT:
A convertible railway hopper car has parallel longitudinal beams defining the sides of a hatchway for filling the car with granular material from a spout, and hinged on the upper margins of the car sidewalls are cargo cover members which may occupy elevated positions in which they form a roof covering the entire car body except the hatchway, or idle positions hanging inside the car body. Hinged hatch elements are mounted on the cargo cover members at one side of the hatchway and are movable between extended positions closing the hatchway and secured to the cargo cover members at the other side of the hatchway, and open positions lying atop the cargo cover members upon which they are mounted. When the cargo cover members are in idle position the hatch elements hang below them.
