of 65 hours and 42 minutes, out of a total of 3,640 hours and 15 minutes scheduled running time, which equates to about 98% availability. Of those 259 breakdowns, 159 were caused by vehicle-related problems. In 2007, the system received funding to improve efficiency by reducing this vehicle downtime. Since the system's completion in 1975, technology for PRTs has advanced considerably, but the control equipment for the Morgantown system changed very little. The control room is said to resemble a NASA mission control room from the 1970s, though the underlying electronics are more modern. , the system's cost per trip is $2.01, the third least expensive (after New York and Boston) for any fixed guideway system in the United States. Operation hours Morgantown PRT operates chiefly as transportation for WVU's students and, as such, runs primarily during class days. During the fall and spring semesters, it operates 6:30 am–10:15 pm weekdays and 9:30 am–5:00 pm on Saturdays. It is normally closed on Sundays. During the summer semester, it is closed (as of 2021). When major WVU eventsnotably football and men's basketball gamesare scheduled to end outside of normal operating hours, the system will run for at least an hour after the end of the event. The system is closed on holidays and during semester breaks. Modernization When it opened, the PRT was controlled by DEC PDP-11 computers installed in 1971. Due to difficulty in procuring replacement parts, these older computers were replaced in 1997-1998 with Intel Pentium computers. A 2010 study recommended renewal of the system given declining reliability caused by its age and the lack of access to replacement parts for key components, such as the vehicles and the control system. The report considered replacement of the PRT with buses but concluded they would be unsatisfactory given the extra traffic congestion and poor travel times that would result. By 2015 reliability had fallen to 90%. In 2012, the university Board of Governors approved $15 million as part of renewal and modernization project. The total cost is projected to be $100–$130 million. The three phase plan is to replace the control and propulsion systems in the current vehicles, installation of a new automatic train control system, upgrade the power supply, repairs to the infrastructure and finally replacement of all the vehicles. Part of the phase 1 work to upgrade the vehicles' control and propulsion system was completed by early 2014
