Abstract
Disclosed is an articulated rail car for transporting two large wheeled vehicular truck trailers in 'piggyback' fashion. The articulated rail car comprises two separate car bodies each supported by single axle railroad wheel truck assemblies mounted at each end of each body. A semi-permanent coupling joins the two car bodies so that the car can articulate around curves and bends in the railroad track. Utilization of the single axle trucks permits the rail car to maintain the normal number of axles (four) for rail cars even though the car is articulated in the center. The car bodies comprise a central spine extending upwardly along the length of the car for providing vertical strength. A tire support surface extends outwardly from each side of the central spine below the level of the central spine so that the vertical height of the wheel vehicular trailers transported by the articulated rail car is reduced allowing easier passage under structures and through tunnels. The car bodies also each include fifth wheel structures which support and unwheeled end of the vehicular trailers and absorb the vibrational shocks normally experienced by moving rail cars.
