FRA 要求 SEPTA 在发生五次火灾后修复老化的 Silverliner IV 列车的火灾风险，但不会强制关闭。 The FRA demands SEPTA fix fire risks in aging Silverliner IV trains after five fires, but won’t force a shutdown.

联邦铁路管理局已命令SEPTA紧急应对自2月以来五起火灾后50年之久的银轮四轮铁路车的火灾风险,要求对所有225辆汽车立即进行检查和消防升级。 The Federal Railroad Administration has ordered SEPTA to urgently address fire risks in its 50-year-old Silverliner IV railcars after five fires since February, requiring immediate inspections and fire protection upgrades on all 225 cars. NTSB将舰队过时的设计和维修做法称为“即时和不可接受的安全风险”,建议暂停,直到安全问题得到解决,尽管FRA的命令并不要求停止。 The NTSB called the fleet’s outdated design and maintenance practices an "immediate and unacceptable safety risk," recommending suspension until safety issues are resolved, though the FRA’s order does not mandate a halt. SEPTA认为火车是安全的, 列举40项缓解措施及减少服务, 但警告全面关闭会耗资20亿美元, 将服务削减三分之二, SEPTA maintains the trains are safe, citing 40 mitigation measures and reduced service, but warns a full shutdown would cost $2 billion and cut service by two-thirds, a financial burden it cannot bear. NTSB已给SEPTA30天时间对其建议作出回应。 The NTSB has given SEPTA 30 days to respond to its recommendations.
