PHILADELPHIA, PA — The U.S. Department of Transportation is providing $13.3 million to replace a twin railcar in SEPTA’s aging Silverliner IV fleet, extending a federal intervention that followed a series of fires and other thermal incidents on the Philadelphia region’s commuter rail system.
The investment will replace two of SEPTA’s roughly 50-year-old Silverliner IV vehicles with newer railcars, according to USDOT. The department said the replacement is intended to improve reliability and safety while lowering maintenance costs.
The funding follows federal inspections and directives imposed after five incidents in which SEPTA commuter rail vehicles caught fire or experienced other thermal emergencies.
USDOT convened Pennsylvania Gov. Josh Shapiro, U.S. Sens. Dave McCormick and John Fetterman, SEPTA leadership, and officials from three federal transportation agencies last year to address the transit system’s operational problems.
The Federal Railroad Administration subsequently issued an emergency order in October 2025 requiring SEPTA to identify the causes and circumstances behind the fires and thermal incidents and develop a plan to address them.
Federal officials also increased the number of rail safety inspectors working at SEPTA facilities and on its equipment to 30.
As part of the response, 223 Silverliner IV cars underwent mechanical inspections and had their thermal sensors replaced. USDOT said there have been no additional fires since that work was completed.
The Federal Transit Administration separately issued special directives to PennDOT and SEPTA in November 2025 requiring action on safety and oversight concerns involving SEPTA’s overhead catenary system.
Pennsylvania subsequently committed nearly $108 million for upgrades that included improvements to overhead catenary wires in the trolley tunnel, advanced inspection technology and enhancements to SEPTA’s control center, according to USDOT.
Shapiro also allocated $112 million for electrical-system upgrades, propulsion-motor overhauls and other work involving the Silverliner IV and newer Silverliner V fleets after SEPTA was required to submit an emergency mechanical inspection schedule for its Silverliner IV cars.
The new $13.3 million federal investment shifts part of that response from inspections and repairs toward replacing the oldest equipment.
“Now, we’re doubling down — investing millions of dollars to help SEPTA transition to cleaner, safer, and more efficient train cars,” Transportation Secretary Sean P. Duffy said.
McCormick described the funding as a step toward improving SEPTA’s safety and reliability and credited the federal government and Fetterman with working to secure the commitment.
The Silverliner IV replacement comes as SEPTA continues addressing safety and maintenance problems identified through the federal intervention, with the latest funding targeting the long-term cost and reliability implications of operating its aging commuter rail equipment.
