Abstract
A method of manufacturing a side frame of a rail car, where the side frame includes a pair of pedestals for mounting wheel sets, includes providing a side frame pattern for forming a drag portion and a cope portion of a mold. Cores that define an interior region of a cast side frame are also provided. The side frame pattern and the cores are configured to constrain a spacing between the pair of pedestals to within about ±0.038 inches.
