This listing is for 10 x on off switch single Lane dead end tracks with concrete barriers and removable track clips, not made by Tyco, made by Bugsworld, to work with us1 trucking. Tracks are approximately 8 1/2 inches long, rails are aluminum covered plastic.Truck or connected track in picture is not included, only in picture for size references. Straight line on switch means live, go! Take your truck out for a drive to do some work! Done for the day, take it back to its parking spot, flip switch to zero, circle, power is cut to that track and you can now drive other trucks to do their jobs! Preset the switch to zero, while out driving and your semi will back in and park perfectly. Pieces are not perfect but very awesome.
