Abstract
The present invention includes a brake beam wear plate or guide for mounting in brake beam guide brackets of railroad car truck side frames and having upper and lower walls which define a slideway for the brake beam lugs. The brake beam wear plate includes a relatively thick rubber cushioning pad on the lower wall to insulate the brake beam lug from vibration shocks and forces and thereby enhance the life of the brake beam.
