A center bowl liner 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 washer is attached to the disc-shaped element, the conductive washer having a profile wherein portions of the conductive 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 supporting the railroad car center plate. The conductive washer, since it may have spring-like properties, will also undertake to bear a limited amount of the load of the railroad car center plate in addition to providing electrical connection between the car and truck. |
