Abstract: This invention teaches an improved apparatus and method to make metal alloy castings, such as subway car undercarriage bearing housings. One embodiment of the invention comprises a core mold assembly unit, wherein the mold unit is filled with molten metal. The core mold assembly units may be further formed of the same material, such as phenolic urethane impregnated sand, which is used to accurately replicate the desired shape of a final desired product.

Abstract: A railcar truck bolster side bearing mounting pad milling machine and method. A milling machine of the present invention includes a pair of milling heads and associated cutters suspended from an overhead frame member. A sliding saddle unit is provided for transporting the bolster into and out of a work envelope of the milling machine. At least one fixturing assembly is attached to the sliding saddle unit to support and fix the position of the bolster in three directions. The bolster is rigidly supported from its underside, thereby eliminating the risk that the bolster may move downward during machining. Since the vertical position of the bolster when presented to the cutters is fixed, thereby the need to raise the bolster into a working position is also eliminated.

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.

Abstract: A high strength steel alloy for use in manufacturing railway car components. The alloy has a chemical composition that meets the industry required specifications for B grade steel and exhibits better mechanical properties, such as higher yield and tensile strengths. Secondary benefits of the inventive steel alloy include enhanced weldability and improved fatigue resistance.
