Abstract
Abstract A wear liner is provided for the roof of the pedestal jaw of a side frame. Movement of the wear liner relative to the pedestal roof is inhibited by projections extending upwardly from the lateral edges of the wear liner and/or depending legs which extend from the wear liner and cooperate with the stop lugs of the pedestal jaw. The need for conventional welding is reduced or eliminated.
