A suspended monorail track system has a box-shaped cross section with flanges extending inward and upward from the bottom edges of the side walls to form an acute angle between each flange and its attached side wall. An opening remains between the flanges extending along the bottom of the track. An intermediate horizontal wall may be added below the top wall to form an enclosed channel for power and signal cables within the track. A number of power and signal conductors extend along the interior surfaces of the track to provide electrical contact with vehicles moving along the track. Signal conductors are used to prevent collision between vehicles. Each vehicle is suspended from the track by a bogie assembly extending through the opening along the bottom of the track. The bogie assembly is supported by load-bearing wheels riding on the upper surfaces of the flanges, and stabilized by a second set of wheels rolling along the bottom surfaces of the flanges. A series of markings, such as vertical stripes, fixed along the interior of the track are optically scanned from the bogie assembly and used to regulate the speed of each vehicle.
