Port Authority T service resumed normal operations about 9:30 p.m. on Wednesday evening and will run on a normal schedule during the Thursday morning rush hour.
The T had been running on a single track between South Hills Junction and First Avenue Station through much of Wednesday due to a weather-related rail fracture at the Station Square station. The fractured line has been repaired.
This caused light some light rail delays during the Wednesday afternoon rush hour and forced buses that normally use the Mt. Washington Transit Tunnel to follow detours.
Buses that were detoured today will resume their normal routes on Thursday morning through the tunnel.
The 52 Allentown line remains out of service due to the earlier winter storm. Snow accumulation alongside the tracks prevents the safe travel of rail vehicles on that line.
