Abstract: A method of casting an object, usually a railroad wheel, is provided. A graphite mold having a drag section and a cope section requires a plurality of riser openings in the cope section to ensure proper dimensional accuracy of the cast railroad wheel by allowing molten metal to continue to feed downwardly through the riser openings to the cast wheel cavity during initial cooling.

Abstract: A cast metal sideframe for use in a railway car truck has a spring seat for supporting the springs of a spring set. The sideframe is molded using a core that includes a portion for defining the exterior surface of the spring seat. The core can be a single piece or multi-piece core. The spring seat includes a plurality of aerodynamically-shaped spring retainers formed on the top face spring seat.

The aerodynamic shape may include forming at least some of the side walls of the spring retainers at an obtuse angle with the top face of the spring seat. The spring retainers may have concave top faces so as to reduce the volume of material comprising the spring retainers.
