The Southeastern Pennsylvania Transportation Authority (SEPTA) will hold its Trolley Tunnel Blitz from August 9 to August 19, 2019, in the Center City tunnel for power, track and station improvement projects to take place. Trolleys will use their alternate diversion service routing to connect to SEPTA's Market-Frankford Line at 40th and Market Streets.
"The Trolley Blitzes allow our crews to get productive work windows to complete necessary repairs and improvements they otherwise would not be able to because the tunnel is used 24 hours a day," said Jeffrey Knueppel, SEPTA general manager. "The program we have implemented over the past six summers has vastly improved the Tunnel's infrastructure and greatly increased trolley service reliability through the tunnel."
Projects on the five-mile, single loop Center City tunnel will include:
- Replacement of curved rail;
- General track repair;
- Maintenance work to substations;
- Performing heavy maintenance tasks at all stations;
- Testing emergency generators and lighting;
- Addressing water leaks at stations and in the tunnel; and
- Inspecting, testing and maintaining track circuits and other signal aspects.
"The projects we work on during the blitzes improve safety and service reliability throughout the Trolley Tunnel," added Knueppel. "We thank our customers for their continued support and understanding during these closures. We will work to make this year's blitz as productive and successful as in previous years."
