 Morgantown PRT is still in continuous operation at West Virginia University in Morgantown, West Virginia, with about 15,000 riders per day ().It successfully demonstrates automated control, but was not sold to other sites because the steam-heated track has proven too expensive for a system that requires an operation and maintenance budget of $5 million annually.From 1969 to 1980, Mannesmann Demag and MBB cooperated to build the "Cabinentaxi" urban transportation system in Germany.
