SEPTA train inspections: How many are left?

Tracking progress on Silverliner IV inspections and when Regional Rail service will return to normal

Rail cars inspected

SEPTA is rushing to inspect 225 Silverliner IV rail cars that make up about two-thirds of the Regional Rail fleet following an emergency order from the Federal Railroad Administration.

The transit agency has until Oct. 31 to complete the inspections, which were recommended after the National Transportation Safety Board released a report investigating five fires that occurred on the Silverliner IVs this year.

As of Oct. 9, SEPTA said that crews can handle about six Silverliner IV cars a day, with a goal of ramping up inspections to handle 12 cars a day with five-person crews per car.

Although SEPTA is rotating cars in and out of service for the inspections — instead of yanking all 225 from service at once — riders have experienced significant delays and some trains have been outright canceled. Without a full fleet, SEPTA says it is unable to respond as easily to typical delay-causing events, such as power outages and bad weather.

Riders should check the SEPTA app for real-time updates on how trains are running.

As the deadline approaches and delays persist, The Inquirer is tracking SEPTA’s inspection progress.

“We’re looking for any signs of overheating or damage to any of the circuits, physical damage, making sure the bolted connections are tight,” said Greg Buzby, manager of Regional Rail engineering. “There’s also electrical testing that we have to do to make sure the insulation has its integrity.”

Inspections remaining: 225

NTSB releases report

Noting that the Silverliner IV cars’ “outdated design … represents an immediate and unacceptable safety risk,” the National Transportation Safety Board urged SEPTA to sideline all the Silverliner cars immediately and to retrofit or replace them as soon as possible. The Silverliner IVs went into service between 1974 and 1976, with technology that was designed even before that time.

The NTSB’s findings are advisory.

The Federal Railroad Administration, which regulates freight and passenger railroads, ordered SEPTA to undertake the inspections, concluding “that SEPTA’s maintenance and operation of its passenger rail equipment requires additional oversight and corrective action.”

Inspections remaining: 225
