2020 Trolley Tunnel Blitz

Trolley Tunnel Blitz

Starting Friday, July 10 at 10:00 p.m. and CONTINUING THROUGH Monday, July 20, 2020 at 5:00 a.m.

SEPTA forces will work around the clock for ten (10) days, tackling critical track and power maintenance and upgrades, station upgrades and painting, tile replacement and maintenance work, and intensive tunnel, track and station cleaning as part of the 2020 Trolley Blitz

2020 Blitz Work

  • Track: Replace Trolley Tunnel track curved rail along the Eastbound sides of the Tunnel at 15th St and 36th Streets
  • Power: Replace old wood overhead protection boards with a new fiberglass protection board system Westbound between 22nd & 30th Street Station.
  • Communications & Signals: inspect and complete maintenance on entire signal system while replacing LED lenses and lights as necessary; and perform signal testing at Ludlow Interlocking.
  • Bridges & Buildings: Heavy cleaning, inspection, and maintenance at all stations including tile, railings, and partition screen repairs; painting; and installation of bracing beams.

Changes to Service


  • Trolley Routes 10, 11, 13, 34, and 36 will temporarily divert to 40th & Market Sts.
  • Customers may transfer at 40th St. to the Market Frankford Line for service to/from Center City
  • For late night travel, customers can transfer to Market-Frankford Line Weekday Night Owl Bus Service or the all-night Train service on weekends while this work takes place
  • Please look for signs posted at the 40th St. Portal and at stations for service information. Directional signage will help you navigate the system during the Blitz, with tips on how to access service during construction, stairway and station closures, and boarding information

Why the Blitz is Needed

Giving SEPTA forces the opportunity to tackle maintenance, track construction, station facility, and safety improvement work in a concentrated period of time reduces the number of late night and weekend outages over the course of the year. On average, 700 vehicles operate through the five-mile Trolley Tunnel every day. As with previous Blitz campaigns, this work is scheduled during the summer when our ridership is traditionally lower in an effort to impact the fewest number of regular customers.

We thank you for your cooperation and your patience while we continue our work to improve service, safety, and travel comfort in the Trolley Tunnel

Customer Information During the Blitz

ALWAYS be aware of your surroundings and LOOK for signage posted at stations for boarding information. DO NOT enter areas that are gated or blocked off at any time. WE are committed to providing YOU with a safe riding experience and environment
