The unique center plate portion comprising a generally cubic center plate pocket defined between a pair of spaced and parallel center plate pocket end walls, extending perpendicularly between the parallel side walls of said draft sill, and a floor wall member forming a lower wall of the center plate pocket having a cylindrical periphery downwardly from an underside of the draft sill, and having a circular outer face with an aperture axially disposed through the circular outer face to receive a kin-pin of the railway car truck.
