Abstract
An auto rack sidewall bumper guard device for auto rack railroad cars eliminates contact between a vehicle door and the sidewalls. The bumper guard device includes a mounting plate and a plurality of horizontally extending vertically spaced-apart relatively low profile bumpers extending from the mounting plate. The mounting plate is adapted to cover the sidewall panel and part of each adjacent vertical posts to prevent the vehicle doors from contacting the sidewall panels and vertical posts.
