In 1975, the Morgantown Personal Rapid Transit project was completed. It has five off-line stations that enable non-stop, individually programmed trips along an track serviced by a fleet of 71 cars. This is a crucial characteristic of PRT. However, it is not considered a PRT system because its vehicles are too heavy and carry too many people. When it carries many people, it operates in a point-to-point fashion, instead of running like an automated people mover from one end of the line to the other. During periods of low usage all cars make a full circuit stopping at every station in both directions. 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.
