The age and size of SEPTA’s trolley network makes short-term, partial system shutdowns necessary to build the inclusive and efficient transit system our region needs. That’s why we recently experienced a 30-day shutdown of the trolley tunnel. This year—in addition to the maintenance by SEPTA—PennDOT worked on the tunnel under the Schuylkill River.
SEPTA crews worked around-the-clock ⏱️ beginning Friday, July 11, 2025 thru Sunday, August 10, 2025 tackling critical track, power, and signal maintenance, replacing worn track and overheard contact wire, clearing drains, cleaning platforms, removing graffiti, painting, and performing lighting upgrades as part of the 2025 Trolley Tunnel Closure.
This work also prepares us for Trolley Modernization as we upgrade our vehicles and infrastructure for a 21st century light rail system.
Trolley Modernization is a once-in-a-generation opportunity to re-imagine one of the nation’s largest—and oldest—light rail networks to dramatically improve transit accessibility, capacity, and reliability. This project is a key part of SEPTA’s plan to create a seamless transit network that empowers everyone in our region with safe, reliable, and accessible mobility choices.
Here’s how the 30-day closure and the work accomplished will advance our Trolley Modernization efforts:
Accessible Trolleys
Upgrading the tunnel’s electric system in preparation for new, fully-accessible trolleys making these lines ADA compliant. SEPTA isn’t just maintaining existing assets—we’re preparing for the future.
On-Time and Reliable Trolleys
Replacing worn track and overhead contact wire improves reliability by reducing delays and bottlenecks caused by aging infrastructure.
Our trolley system relies on a vast signal system to run frequent and safe service. Crews performed tests and maintenance work on the entire tunnel signal system—including intensive maintenance work on select switches.
Better Customer Experience for Riders
Cleaning platforms, clearing drains, removing graffiti, painting, and performing lighting upgrades improves the customer experience by giving our underground stations a summer makeover. Customers will also notice new or rather no farelines/turnstiles at 19th St Station and 22nd St Station. Moving forward customers will tap when they board the trolley.
We appreciate your patience and understanding as our crews completed this critical work.
The tunnel officially reopened for service on Monday, August 11, 2025. As scheduled!
