Abstract
A conventional over-the-road tractor is modified to include a rail car coupling assembly mounting a rail car coupler in tandem behind the conventional fifth wheel for selective movement into and out of the path of conventional trailer coupling movement to permit of selective coupling with a trailer or rail car. When operating in the rail car coupling mode the conventional fifth wheel boom assembly is actuated to effect, via the rail car coupling assembly, a partial weight transfer from the rail car to the traction unit.
