Abstract
A gap sealer for covering the gaps between horizontally extending and vertically spaced apart sidewall panels on auto rack railroad cars and between sidewall panels and the floor, roof or vertical posts. The gap sealer is a single piece of extruded plastic having a head attachable to a flange of a sidewall panel and a tail or flap biasing against the flange of a vertically adjacent sidewall panel, the floor, roof or post, such that the body of the gap sealer covers the gap to prevent air passage. The gap sealer may also include a bumper which protects vehicle doors from contacting the sidewall panels and risking damage. An individual bumper may also be used to protect vehicle doors, and be attached to a sidewall panel by a unique fastener.
