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.
