Zusammenfassung:	An apparatus and method for molding a freight car yoke with a one piece core is disclosed herein. An exemplary one piece core may be used with a core mold upper half and a core mold lower half mated at a common split line to define a mold cavity which replicates the molded exterior features of a freight car yoke. The one piece core may replicate all of the molded internal features of a freight car yoke. An apparatus may use a pair of one piece cores to produce a pair of freight car yokes. An exemplary method can utilize the apparatus to produce a pair of freight car yokes through a single pour, using a pair of one piece cores. In an exemplary embodiment the one piece cores are constructed from a cold box with phenolic urethane treated molding sand.
