Zusammenfassung:	The number of cores used in casting sideframes is reduced. A pair of end cores and a center core are placed in a mold with cope and drag portions. Each core includes integrally-formed portions for defining portions of the interior surfaces of the sideframes. The integrally-formed portions may include a portion for defining the side window of the sideframe formed integrally with other portions, and may include a pedestal portion formed integrally with other portions. The integrally-formed portions may contact both the cope and drag portions of the mold. The end cores may include integrally formed core prints for supporting the core in the mold. The integrally-formed portions of the center core include connections that are formed integrally with the other portions. Molten metal is introduced into the mold to cast the sideframe.
