An improved center sill construction is provided having sill side castings for laterally positioning and holding a drawbar evenly within a center sill, the sill side castings being easily removable without substantial damage to the center sill. The sill side castings are open ended in the direction of the draft loads and center sill reinforcement means are provided to accept the longitudinal draft load of the drawbar. Thus, the heavy loads are eliminated from upon the sill side castings and the sill side castings may be adequately secured within the center sill by a light weld which is external to the center sill. |
