PITTSBURGH (KDKA) -- Some changes will be coming to the T next month. According to Port Authority, the "Blue Line Library" is becoming the "Silver Line Library" starting March 15.

The Blue Line Library route is now known as the Silver Line Library route, effective Sunday. The Port Authority had announced the change Feb. 18.

Pittsburgh Regional Transit officials said an overhead power line fell on top of a Silver Line rail car just before 9 a.m. It sparked a fire on the roof that went out on its own.
