A Belgian consortium has developed a medium-capacity, steel-rail light metro concept which will be first installed in Liege with the 16-km line due for opening in the late 1980s. The so-called TAU system uses lightweight cars on a 1000-mm track which permits small tunnel cross-section and prefabricated tunnel concepts. Automated operation is designed to minimize operating costs. The line will serve directly 14% of the Liege population and intersecting bus lines will be redirected to act as feeders to the rail transit. The modular trainsets are powered from a 3-phase third-rail system. Trucks are designed with independently rotating wheels and hinged frames to negotiate 10-m radius curves. Control of trains is achieved using three computers in the operations and three processors on each vehicle. There are no track circuits.
