Abstract
A rail car end assembly comprises upper and lower tracks for guiding and stabilizing multi-panel rigid doors moving between open and closed positions. End posts are located inside the car and spaced inwardly from respective side wall end portions. The door pass between the space between the end posts and the side wall end portions when moved into the open position. A latch arrangement is provided which latches the door in the open and closed positions. The latch arrangement includes a lower pin engaging a keeper adjacent the lower track, and an upper pin engaging a keeper supported on an elevated platform in the car. The pins are joined by a cable for synchronous movement to lock and to release the doors. Each door has a follower engaging the upper track for guiding the door. In the closed position, the follower engages a stop on the track which reinforces the upper portion of the door against outward movement. Each door has an inner panel with an inwardly projecting anti-pilferage barrier in the form of a flange which projects under the roof.
