This and the next four photos show drilling and boring of the 3 inch center pin hole. The center pin goes through both the frame and truck bolster, for the purpose of keeping the trucks from coming loose in case of a derailment, or roll-over.....heaven forbid! The center pin is cross-keyed , loosely in place, not firmly cinched down with a nut.
