ABSTRACT OF THE DISCLOSURE A wear member for a railway vehicle and method of making the same are provided herein. The wear member has a U-shaped support that is provided with a bight and a pair of parallel legs and carrying on the bight thereof anti-friction polymeric material. The support is made of structural material of substantially uniform thickness throughout, the structural material having a plurality of corrugations defining the bight of the support with each corrugation having the uniform thickness throughout substantially its entire configuration and having an end surface spaced from and coplanar with the end surfaces of the corrugations adjacent thereto whereby the corrugations provide structural strength for the bight of the support. The polymeric material is supported by certain of the corrugations at just the adjacent and coplanar end surfaces thereof. In the method, the forming step comprises providing a structural material of substantially uniform thickness throughout and defining a plurality of corrugations in at least a portion of the bight Of the structural material. Each corrugation has such uniform thickness throughout substantially its entire configuration and has an end surface spaced from and coplanar with the end surfaces of the corrugations adjacent thereto. The corrugations thus provide structural strength to the portions of the polymeric material which are being supported by certain of the corrugations at just the adjacent and coplanar end surfaces thereof.
