Designed to keep train crews safe as they switch ladles of molten steel within a steel mill complex, the HO Scale Steel Mill Ladle Buffer Car kit from State Tool & Die builds a specialized heavy-duty car as used by prototype steel mill railroads. This is a version converted from a ladle car. This easy-to-build kit includes injection-molded parts as well as appropriate trucks with metal wheels and Kadee(R) knuckle couplers.
