West Virginia Universitys Personal Rapid Transit (PRT) will not be in service Sunday, May 6, through Sunday, May 20, as the system undergoes necessary maintenance to enhance its long-term viability.

Service resumes Monday, May 21, the first day of classes for the summer session.

Officials are using the down time between the end of the spring semester and the beginning of the summer term to improve the systems power cabling, when many students will be out of town and potential passenger use is expected to be light, said Robert Hendershot, WVU Department of Public Safety and Transportations assistant director for PRT operations.

During this time, Mountainline bus service will continue to be available for free to all students and employees with Mountaineer Card. Consult the Mountainline schedule by visitinghttp://www.busride.org/WVU/dorms.htm, or call 291-RIDE (7433). For rider without a WVU ID , the fare is 75 cents per ride.

Officials expect the PRT to continue to be a key component of transportation planning and future needs on the WVU campus and within the city of Morgantown.

The PRT is proceeding with our long-term modernization program that will ensure the viability of the system,Hendershot said.These programs include replacing all of our old electronic systems, modernizing all of our communication systems and, like the electrical cable replacement program, upgrading the infrastructure of the PRT system.

We have a network of high voltage electrical feeds from the Evansdale switchyard to each of our five electrical substations that provide power for the PRT system,Hendershot explained.The existing power cabling is over 30 years old and is reaching the end of its useful life. We are undertaking a project to replace all of this cabling over the next three years as a part of our long-term maintenance program.

Officials regret any inconvenience this may cause, he added, especially during Commencement Weekend, May 11-13.

The PRT , now over 30 years old, is still a highly-advanced transportation service. The computer-driven, electric-powered system serves approximately 15,000 riders a day during the school year and has served 56 million people over its life span.

An international seminar,PRT: Realities and Futures,will be May 4-5 at WVU s Erickson Alumni Center to discuss advanced transportation systems such as WVU s PRT as well as ideas to help solve traffic congestion.
