SEPTA is temporarily removing some train cars to conduct inspections after a pair of fires this year, officials said on Saturday.
The transit service said it is trying to avoid entire trains being canceled, and will instead mostly rely on shortening trains from six to four cars to two to three cars, officials said.
It is unclear how long the inspections will impact train service, but SEPTA officials said train cars are usually sidelined for as little as less than 24 hours.
According to SEPTA, there are two train fires this year that are possibly linked to the cars pulled from service.
The first fire occurred on Feb. 6, 2025, on the Wilmington/Newark Line train near the Crum Lynne Station, and the second was on July 22, 2025, when the Paoli/Thorndale line train caught fire at the Paoli station, officials said.
The railcar inspections are happening as part of an investigation into the fires that is in coordination with the Federal Railroad Administration and the National Transportation Safety Board, SEPTA officials said.
The investigation into the two fires is not related to the investigation into what caused 40 buses to be destroyed or damaged in a fire at a "bus graveyard" in Nicetown on June 5, 2025.
However, the FTA is also investigating the "bus graveyard" fire as part of an investigation into decommissioned lithium-ion battery vehicles.
