Abstract

A one-piece, cast traction pin for use with railway cars. The traction pin is used to connect the railcar cab with the railcar truck assembly. The traction pin includes a mounting plate cast integral with the pin, thereby eliminating the use of multiple welded plates. The one-piece cast traction pin is also solid to reduce the potential for stress related failure of the traction pin during normal operation of the railway car.
