| 摘要 | A gondola car has a door and an associated door frame the end. The door hangs hingedly from the header of the frame. The header runs across the top of the door opening and is connected to the top chords at either side. The door posts are positioned inside the side sheets and tie into the header at each upper corner. The side sheets lap onto the door posts to allow longitudinal adjustment of the side assemblies and the door frame relative to each other, at assembly. The side posts are connected to the header with a tie plate that is bolted to both members. The car may also have a tarp dome at each end. The tarp dome has non-welded connections that have play to permit the tarp dome to accommodate movement of the top chords. | ||||||
