ABSTRACT:
A conductive center bearing liner for railroad car center plate assemblies comprising a bowl shaped or flat round horizontal member formed from a cross-linked ultra high molecular weight polymer specially mixed with a conductive material shaped to define a floor portion and alternative embodiments with an upstanding side wall. Another embodiment concentrates the conductive material in a selected sector of the disk portion of the liner. The conductive liner eliminates the need to incorporate special apparatus to ground the car body center plate to the truck bolster bowl. This grounding method eliminates the wear and erosion that occurs by grounding using conventional methods.
