Abstract
A resilient clip on pedestal wear plate comprises a base with two opposing side lips for resiliently holding the base on a railway car side frame. When installed, the wear plate serves to prevent wear on the load bearing surface of the pedestal. The side lips of the wear plate comprise a center portion with spring arms extending therefrom to resiliently attach the plate to the side frame. Because the spring arms do not depend on bending of the base for their resiliency, the wear plate of the invention provides improved service stress capabilities.
