Abstract
A core assembly for creating interior spaces in a railcar coupler knuckle is designed to be set in a cavity with cope and drag sections. The cavity is shaped to form a railcar coupler knuckle and includes a first wall that forms the substantially vertical outside wall of the tail of the knuckle. The core includes a kidney section with a rear core support section that extends at least 0.5″ outside the first wall of the cavity when the core is set in the drag.
