  • Auto rack railroad car panel bumper guard
    Patent number: 6805523
    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 contact member has a lesser thickness than the arms to absorb the forces of the vehicle door.
