Abstract:
A railroad car center plate assembly liner for placement between a car body center plate and a truck bolster bowl of a railroad car, said liner comprising:a body sized to be placed between said car body center plate and the truck bolster bowl, said body including a substantially flat load-bearing portion being of a thickness defined by a first surface and a second surface, and defining a central opening for receiving a kingpin; and at least one compressible conductive resilient member securely positioned in the load-bearing portion, each said compressible conductive resilient member having a body extending through the load-bearing portion and being of a thickness greater than the thickness of the load-bearing portion, each said compressible conductive resilient member positioned in the load-bearing portion such that conductive portions of the body extend transversely from the first and second surfaces of the load-bearing portion and are operable to provide electrical conductivity between the truck bolster bowl and the car body center plate when the liner is placed between the car body center plate and the truck bolster bowl.
