SEPTA has recently announced that its annual Trolley Tunnel Maintenance “Blitz,” during which trolleys do not operate in the tunnel, is scheduled to begin on Friday, July 12, at 10 p.m. This project is an opportunity for SEPTA crews to replace worn tracks and overhead contact wires in the tunnel and perform some necessary cleaning.

Here’s how the trolleys will operate during the Blitz, which will take place from July 12 through July 29 (see the map):

Route 10 [T1], Route 34 [T2], Route 13 [T3], Route 11 [T4] and Route 36 [T5] are suspended between 13th Street and 40th Street Portal until 6 a.m., July 29. Subway-Surface Trolleys [T] pick up and drop off riders at any bus stop along the diversion routes.

• Eastbound trolleys go to 40th and Market streets where riders can transfer to the eastbound Market-Frankford Line [L] for service to Center City
• Westbound riders can take the westbound Market-Frankford Line [L] to the trolleys at 40th and Market streets for service to points west
• For late-night travel, riders may transfer to Market-Frankford Line [L] Night Owl Bus Service
• Bus routes 21 and 42 provide local east/west service between West Philadelphia and Center City

As with previous Blitz campaigns, which started in 2014, this work is scheduled in the summer when ridership is traditionally lower in an effort to impact the fewest number of regular riders.

The work underway during this year’s Trolley Blitz helps SEPTA prepare for modernization, the complete replacement of the trolley fleet with state-of-the-art, accessible vehicles.
