ABSTRACT:
A unitary cast draft sill for welding to the center sill of a railroad car comprises a unitary cast structure with the following elements and features: A horizontal top wall has a pair of side walls depending therefrom with a bottom portion having flanges extending horizontally outward from the side walls. A vertical inboard end wall joins the bottom portion, the side walls and the top wall and has a transition element extending from the inboard side portion thereof to telescopically enter adjacent portions of a railroad car center sill. A center filler plate pocket is formed by the inboard end wall, portions of the side walls and the top wall and an internal vertical wall spaced in the outboard direction from the inboard end wall to form a cavity opening at the bottom portion to accept and mount a center filler plate in welded relation. Rear draft lugs are formed at the outboard side of the internal vertical wall and adjoin the side walls. On the outboard end portion of the cast draft sill, it has a horizontal top striker above the coupler shank opening, a carrier to vertically support the coupler shank and a key slot through the side walls for a coupler draft key.
