ABSTRACT:
A center bowl liner is provided for use between a center plate of a railroad car and a center bowl surface on a truck bolster. The center bowl liner includes a disc-shaped element having top and bottom surfaces and a central opening for receiving a center pin. A conductive spring washer is attached to the disc-shaped element, with the conductive spring washer having a contoured profile such that portions of the conductive spring washer are exposed at the top and bottom surfaces of the disc-shaped element and create an electrical connection between the railroad car center plate and the center bowl on the truck bolster. The disc-shaped element acts as a load-bearing element generally supporting the railroad car center plate. The conductive spring washer, since it has spring-like properties, will also undertake to bear a limited amount of the load of the railroad car center plate in addition to providing an electrical connection between the car and truck.
