Abstract: A method of manufacturing a side frame mold for casting a side frame of a railway car truck includes forming a drag and a cope portion of a mold from a casting material to define an exterior surface of a drag portion and cope portion, respectively, of the side frame. The mold includes a portion for casting the pedestal jaw of the side frame. The drag and the cop portions are then cured.

Abstract: A method for casting a railroad component such as a component of a railway car truck. The component of the railway car truck may be, e.g., a side frame or a bolster of the railway car truck. The method includes manufacturing the railroad component made of steel in a no-bake manufacturing process including use of a chemically-bonded sand system that results in a sand mold from which the railroad component is cast. The railroad component resulting from the no-bake manufacturing process has a surface finish less than 750 micro-inches RMS, resulting in increased fatigue life compared to a railroad component manufactured by a green sand process.

Abstract: A method for manufacturing a bolster of a railway car truck includes providing a drag portion and a cope portion of a mold. In a main body section of the mold, a parting line that separates the drag portion from the cope portion is substantially centered between portions of the mold that define brake window openings in sides of the bolster. One or more cores are inserted into the mold and a molten material is poured into the mold to thereby case the bolster.
