PITTSBURGH (KDKA) -- A computer problem halted the entire light rail system of Pittsburgh Regional Transit on Monday morning.

A glitch in a computer server just after 9 a.m. left the rail control center unable to see the locations of any of their trains. PRT described the issues as a loss of "all controls and functions of the rail system."

No passengers were stranded because the cars could still move and made their way back to South Hills Village.

Just after 11 a.m., service inbound from South Hills Village was restored. About an hour later, the entire system was back online and getting back to normal service.

"Rail cars are leaving South Hills Village to head inbound, but there will not be any outbound trips from the North Shore for about 45 minutes," PRT said in a tweet. 

PRT said riders should expect the T to be running about 10 minutes behind schedule.

No word on what caused the problem.
