Abstract of the Disclosure The front face of an Association of American Railroads (A.A.R.) type E coupler knuckle, forward of the knuckle pivot center when the knuckle is in closed position, is formed of intersecting surfaces, one of which slopes rearwardly at an angle of ap- proximately 12° with the other surface and intersects the other surface at a location between the longitudinal axis of the coupler and a line parallel to that axis through the pivot pin hole, thereby ensuring complete closing and locking of the mating knuckles of couplers approaching under maximum angling conditions.
