Abstract

E-type and F-type yokes improve the ability of the yokes to be constructed having lighter weight yet function to handle loads from car coupling assembly components, such as, for example, a coupler mounted on the yoke. The E-type and F-type yokes have straps and openings provided in the straps, and are constructed from austempered ductile iron. Embodiments may be constructed with a tail or butt portion that includes sloped walls that form cavities in the butt portion of the yoke, where a supporting structure spans between the yoke rear wall and the draft gear seat wall.
