ABSTRACT:
A rail-draft vehicle employs an ordinary tractor-like apparatus having conventional forwardly extending, boom apparatus and intermediate vehicle means interposed between the tractor-like apparatus and a conventional railroad car for coupling with and moving one or more of the latter along the rails. The boom apparatus is of the type having a pair of power operated, spaced, swingable tool supporting arms extendable to a position substantially forward of the tractor and have mounted thereon a pair of rail wheels which may be selectively lowered into engagement with the rails upon manipulation of the loader attachment, thereby eliminating the need for special rail wheel retracting mechanisms heretofore directly mounted on the tractor. The intermediate vehicle has opposite ends thereof respectively coupled with the three point hitch of the tractor and the railway coupling mechanism of the railroad car, and is provided with a pair of rail wheels which, in combination with the front rail wheels associated with the boom apparatus, provide long wheelbase mounting of the tractor on the rails in a manner to allow highly stabilized operation of the rail-draft vehicle. A compressed air supply for controlling the braking system of the railroad cars is mounted on the tool supporting arms adjacent the forward set of rail wheels in order to improve the weight distribution of the vehicle and thereby further increase operating stability.
