A friction clutch type draft gear assembly includes a housing having an open front end and a closed rear end forming a ledge for enabling a longer buff and draft travel while fitting into a 24.625 inch draft gear pocket. A friction clutch mechanism includes a pair of outer stationary plate members, a pair of movable plate members, a pair of inner stationary plate members having an inner surface which is tapered at an angle of approximately 4.5.degree., a pair of wedge shoe members having an upper surface which is tapered from a point disposed inwardly from the tapered outer surface inwardly toward and at an acute angle relative to a longitudinal axis of the friction clutch mechanism, and a center wedge member which includes a pair of correspondingly tapered surfaces frictionally engageable with the upper tapered surface of a respective one of the pair of wedge shoe members. The tapered upper surface of the pair of wedge shoe members is tapered at an angle of approximately 49.0.degree. 50.0.degree.. The pair of tapered surfaces of the center wedge is tapered at an angle of about 49.5.degree..
