FRA Orders Removal of SEPTA Silverliner IV Cars

Federal investigators have traced multiple onboard fires on SEPTA's aging Silverliner IV fleet to electrical and propulsion-related components and cited organizational lapses, leading the NTSB to recommend suspension of the cars and prompting an FRA emergency order. Approximately 225 of SEPTA's 390 Silverliner IV cars (built 1974–76) are being removed from service for enhanced inspections and repairs. SEPTA is conducting comprehensive inspections, installing new monitoring systems including live video and thermal detectors, instituting audible fault alarms, and providing operator and mechanical training while submitting a 30-day compliance plan to regulators. The agency warned riders to expect cancellations, delays and crowded trains, with disruptions likely to continue beyond peak commute periods. SEPTA and federal agencies say the cars predate modern fire-safety standards, complicating mitigation, and officials have flagged longer-term transit funding questions as the agency weighs replacement options. Riders are urged to check the SEPTA app and website for real-time service updates and alternative travel information.
