ABSTRACT:
A method of repairing railway trucks in which the sloped surfaces of the truck bolster ends have become worn during service is provided that avoids the hetertofore required restoring of the sloped surfaces with weld material. An improved replacement friction shoe having tapered elastomeric pads which conform to the abutting service worn sloped surfaces of the bolster ends is installed to greatly reduce further wear on the bolster ends.
