Abstract
The present invention provides a joint for transferring load from the underframe of a locomotive to the cant rail of its car body. The joint includes a base connected to the underframe of the locomotive with a body portion attached thereto. This body portion carries a generally diagonally situated member connected to the cant rail of the car body of the locomotive, such that the load from the underframe is transferred to the base of the joint, through the body portion of the joint, to the diagonally situated member and to the cant rail during bending of the underframe of the locomotive. In another aspect of the present invention, a joint is provided which is generally flexible to accommodate bending of the car body and underframe of the locomotive relative to their respective stiffnesses.
