ABSTRACT OF THE DISCLOSURE A wear resistant liner for use between a center plate of a body bolster and a bolster bowl of a truck bolster of a railway vehicle is provided herein. Such liner includes a deformable polymeric laminate com- prised of a first deformable polymeric material which is adapted to reduce load concentration against a peripheral annular flange of the bolster bowl and a second deformable, polymeric material which provides an antifriction surface engaging the flange with the laminate. The first material is an inner part of the liner means and the second material being an outer part of the liner means and a different material than the first material. This results in an increased operating life for such flange because the laminate is adapted to deform into the contour of the flange.
