A disappointing update for trolley commuters: the Center City trolley tunnel will remain closed until at least the end of December. No specific reopening date has been given, but officials are aiming for a January comeback.
The tunnel's closure, which began in November, is due to repairs on the overhead catenary wire system. Two separate incidents in October, where trolleys were halted and passengers evacuated, highlighted the need for urgent action.
Kate O'Connor, SEPTA's assistant general manager, emphasized the importance of reducing risks before reopening. The issue stems from a change in the size of brass sliders, which hold carbon chunks that coat the wires powering the trolleys. The switch from 3-inch to 4-inch sliders was intended to reduce maintenance costs, but it backfired, especially in the tunnel's curved sections.
SEPTA's testing of the 4-inch sliders was insufficient, leading to the current situation. The transit authority had to revert to the 3-inch sliders, but the damaged overhead wires caused them to wear out faster.
Jason Tarlecki, SEPTA's deputy chief engineer, described the sound of the brass rubbing after less than a day. The excess wear on the copper wiring left it damaged, requiring a complete replacement of the five-mile overhead system.
The repair process has been delayed due to pandemic-related supply chain issues. New wiring needs time to develop a carbon coating, and SEPTA has been running trolleys during the closure to facilitate this. Additionally, tests are being conducted to prevent future issues.
Councilmember Jamie Gauthier and State Rep. Rick Krajewski will lead a canvas on Thursday, joined by SEPTA riders and advocates, to voice their concerns about the tunnel's lengthy closure. Gauthier emphasized the impact on West and Southwest Philadelphians, who rely on the trolley for their daily commute.
Even after the tunnel reopens, there's a possibility of further closures for wiring replacements. It's a challenging situation, but necessary to ensure the safety and reliability of the trolley system.
So, while we wait for the tunnel's reopening, let's discuss: do you think SEPTA's handling of this issue has been adequate? What could they have done differently? Share your thoughts in the comments!
