During several weekend in September SEPTA’s T trolley tunnel will be closed, and all five Philadelphia trolley lines will be bused for their full on-street portions and diversion routes. Riders can transfer at 40th and Market for connection to the L subway line, to and from Center City.
The trolley tunnel will close at 2 am on Saturdays, with a gradual transition to busing through the overnight hours. All five T lines will be fully bused by 5 am Saturday until 5 am Monday on the following weekends:
- Saturday, September 12 to Monday, September 14
- Saturday, September 19 to Monday, September 21
- Saturday, September 26 to Monday, September 28
On Monday mornings, some T4 and T5 trips continue to operate as a bus to 40th St Portal for select trips through the afternoon hours.
These closures are necessary to allow SEPTA to make critical repairs to an electrical substation at 33rd St. The substation, which powers both the Trolley Tunnel and the diversion route, experienced water intrusion in recent weeks that makes these repairs necessary to avoid potential unplanned outages.
