摘要： A multi-deck rail car having an interior cavity and an end opening for loading and unloading lading is provided with a pair of door assemblies, each of which includes a plurality of panels. Each door assembly is pivotally movable for closing at least a portion of the end opening. Double vertical pivots mount each of the door assemblies and are provided such that they move the door assemblies between their respective open position, storage position and closed position. The double vertical pivot means are cranks pivoted at either end to permit pivoting of the door assemblies for storage within the rail car, when their panels are folded back upon one another. A lock for the doors includes a rigid projection extending from the edge of a first one of the panels behind and past an adjacent edge of the second of the two panels and in register with a cutout in the adjacent edge of the second panel. A locking bar is mounted on the second door for reciprocal movement in a vertical direction such that gravity can act to lock the door. A locking cam is pivotally mounted adjacent the bar for engagement with a stop projection on the bar to selectively permit the bar to be lifted.
