Passengers are facing delays on Pittsburgh's light rail.
The Port Authority of Allegheny County says Friday's delays are related to a power problem.
On Twitter, the Port Authority said the problem stems from an issue with a switch at the Allegheny Station.
Light rail delays on Blue and Red lines remain. Crews continue to work on the switch at Allegheny Station. Thank you for your patience.
