A track vehicle employing a rail track system comprising a vehicle frame, a pair of parallel side rails attached to each side of the frame, drive assemblies comprising a pair of pneumatic tires with drive sprockets therebetween, rotatably attached to the frame via torsion bars proximate each end of the side rails such that the tires extend below the frame, a continuous track comprising torsion and compression links, in which one torsion link and one compression link form an assembly as two sides of a triangle, with an apex that pushes against, and slides along, the side rails, and a pair of track ends affixed to the track, the links being operably associated with the drive sprockets, and surround the tires such that the links pass between the tires while the track is driven, wherein the track ends extend against the track to provide increased ground contact, and, a drive motor attached to the frame, and operably associated with the tires and sprockets to drive the track.
