Abstract
A wear plate is installed on the downwardly facing surface of the pedestal opening of the side frame of a railway truck. The wear plate includes a base and a pair of lips extending upward from opposite sides of the base. The lips resiliently engage or clamp onto opposite sides of the pedestal with the base protecting the downwardly facing surface. The base is slightly bowed and is formed a convex shape relative to the downwardly facing surface before installation, such that upon installation, the base of the plate is free of undesirable distortions.
