Abstract
The present invention reveals an auto rack sidewall panel bumper guard for auto rack railroad cars which eliminates contact between the vehicle door and the sidewall panel even in extreme heat. The bumper guard includes a pair of opposed mounting bases, a pair of extension arms connected to the mounting bases and a contact member connected to the arms opposite the mounting bases. The contact member has a lesser thickness than the arms to absorb the forces of the vehicle door.
