ABSTRACT OF THE DISCLOSURE: A railway house car side has an elongated opening closed by four doors disposed in end-to-end relation lengthwise of the car with respect to each other, two of the doors, which may be designated end doors, being movable solely lengthwise of the car to uncover the end portions of the opening, the other two doors, which may be designated center doors, being movable transversely, to disalign them transversely of the car side from the end doors and lengthwise of the side alongside of the end doors to uncover the center portion of the opening. The edges of the end doors nearest the respective ends of the car side have beveled flanges engageable with outwardly diverging door stops on the car side to wedge the end doors against the car side when closed and the opposite edges of the end doors have flanges overlaid by the adjacent center door edges to hold the end doors against the car side, and the edge of one center door overlies that of the other to afford a seal between them. Each end door is provided with a manually actuable device for unwedg- ing the door and initiating its opening movement. As a safety feature the side plate of the car mounts a common top retainer rail for both sets of doors comprising a generally S-section elongated member having an upwardly open inner channel forming the top retainer for the center door cranks and a downwardly open outer channel forming the top retainer for the end doors. The side plate also mounts an outwardly extending ledge over- lying the inner retainer channel to prevent the center door crank terminal from rising out of the inner retainer channel, and the web and outer depending flange of the outer retainer channel provide additional obstacles to outward movement of the center door top crank terminals in the event of failure of the common vertical web separating the two channels. An idler safety retainer crank on each door is addition to the operating retainer cranks prevents separation of the door from the car side if the operating retainer cranks fail. Novel gasket construction provides an improved seal between the adjacent doors and between the doors and the car side sill and side plate.
