At a Glance
- SEPTA’s Center City Trolley Tunnel reopens at 5 a.m. on Monday, Jan. 12, 2026
- Crews replaced nearly 5,000 feet of overhead wires since mid-November
- Weekend closures will still occur while remaining wires are swapped
- Why it matters: Riders regain uninterrupted T service from 40th to 15th streets after months of shuttle-bus detours
After months of shuttle buses and route disruptions, SEPTA is restoring normal T trolley operations through the Center City Tunnel.
What’s Changing Monday
All T trolleys will roll through the tunnel starting Jan. 12, 2026, at 5 a.m. The corridor had been shut down since mid-November so crews could replace aging overhead power lines.

SEPTA finished the first major phase-swapping nearly a mile of wire-ahead of schedule, but the job isn’t over.
Still to Come
Additional wire replacements are planned along the five-mile tunnel. Expect:
- Select weekend closures through winter/spring
- T Bus Shuttle service between 40th and 15th streets whenever the tunnel is closed
- Real-time updates on SEPTA’s website and social feeds
Key Takeaways
- Normal T trolley service resumes Jan. 12, 2026, at 5 a.m.
- 5,000 feet of overhead wire has already been replaced
- Weekend shutdowns will continue until every wire is updated
- Shuttle buses will fill gaps during future closures
Riders can finally ditch the detour, but should budget extra time on weekends until the final wires are swapped.
