A wire-replacement project and other maintenance work will close the Regional Rail tunnel between the University City and 30th Street stations this weekend.
The transit agency said the tunnel closure is needed to make emergency repairs to overhead wires. While the tunnel is shut down for that work, crews will also clean trash, remove graffiti and vegetation, trim trees, replace a track section and test Positive Train Control equipment.
Here's how service on the Regional Rail lines that pass through the tunnel will be affected:
Airport Line: Shuttle buses will replace trains between 30th Street Station and the airport terminals. The buses, which will stop at the University City and Eastwick stations, will pick up and drop off passengers at 30th Street and John F. Kennedy Boulevard.
Media/Elwyn Line: Express and local shuttle buses will replace trains. Riders who connect to the line from Chestnut Hill East should leave 30th Street Station to transfer to the shuttle buses at 30th Street and John F. Kennedy Boulevard.
Wilmington/Newark Line: Trains will operate as scheduled, but passengers must transfer at 30th Street Station to continue to Norristown on the Manayunk/Norristown Line.
