Abstract: This invention is a rail grade load/unload rail carrier with primary vertical load bearing sub-assemblies positioned above the carrier body floor. Carrier body sub-assemblies are vertical columns with stay cables attached to rail carrier bar joist sides. The design features carrier body floor elevation slightly above rail grade, and detachable rail wheel bogies outside the carrier body, to enable motor vehicle rail grade loading/unloading. Rail wheel bogie variants may be used for rail gage adaptation. Further, loaded motor vehicles provide rail carrier motive power; drive wheels protruding downward through carrier floor apertures to bear on rail flanking traction strips. Traction strips connect to a vehicle staging platform which has; integral rails, rail line connection, and highway access. Autonomous motor vehicle carrier translation along rails and across the staging area, negates need for conventional rail terminal handling facilities.
