SEPTA Restores Market-Frankford Line After Fire

SEPTA's Market-Frankford Line between 30th Street and Spring Garden stations resumed service Wednesday night after an underground transformer fire disrupted thousands of Philadelphia commuters during evening rush hour. The fire started just after 3 p.m. and caused a power outage affecting multiple stations along the El, transit officials said. No injuries were reported in the incident, and service appeared to be running on schedule Thursday morning.

Rush Hour Disruption

The transformer fire occurred during one of the busiest travel periods of the day, forcing the suspension of service on a critical segment of Philadelphia's subway system. Chopper 3 captured footage of a large first responder presence at Suburban Station, where smoke was seen billowing from underground near the Clothespin Sculpture. SEPTA initially deployed shuttle buses between 30th Street and Spring Garden stations to transport stranded riders, though those buses have since been canceled following service restoration. Many riders reported significant disruptions, with some noting that ride-share prices surged to $50-70 as commuters sought alternative transportation.

Limited Impact to System

The fire only impacted the Market-Frankford Line, while service on the Broad Street Line, Regional Rail, and trolleys continued to run, though they bypassed City Hall. Transit officials said the power outage affected multiple stations along the El between the two endpoints, but didn't specify exactly how many stations lost power or the full extent of the electrical damage. The cause of the transformer fire remains under investigation, and officials haven't said whether similar equipment will be inspected system-wide as a precaution. Riders were advised to expect residual delays following the restoration.

Service Restoration Timeline

SEPTA crews worked throughout Wednesday evening to restore power and resume service on the affected segment. Service was restored Wednesday night, though officials didn't provide a specific time for when trains began running again. By Thursday morning, the Market-Frankford Line appeared to be operating on its regular schedule. Officials haven't said how long repairs might take or whether any ongoing maintenance work will be required at the site of the transformer fire.
