SEPTA commuters are facing delays on a number of regional rail lines this morning, which the transit authority said was due to signal issues.

  4. Fox Chase

  5. Doylestown

  6. Media

  7. Norristown

The delays Thursday came in addition to expected regional rail cancelations announced earlier this week, as SEPTA responds to a Federal Railroad Administration emergency order.

The federal agency ordered SEPTA to conduct inspections of all 223 of its Silverliner IV trains following five fires this year.

These canceled trains included selected trips on the Airport, Fox Chase, and Chestnut Hill West lines.

SEPTA said online it halted these trains as it works to complete the federally mandated inspections of the Silverliner IV fleet by the deadline this Friday.

“The Authority is canceling these trips ahead of time to try to avoid last-minute disruptions and provide a more reliable schedule for riders.”

“Our customers remain at the center of every decision SEPTA makes,” said SEPTA General Manager Scott A. Sauer.

“We understand safety concerns can raise questions, and we want our riders to feel assured we are taking every step possible to ensure their safety as we work to provide critical service.”

SEPTA is the state’s largest mass transit authority and earlier this year was at the center of a funding fight that exposed the commonwealth’s rural-urban divide.

In September, Democratic Gov. Josh Shapiro’s administration granted SEPTA’s request to access capital funds as a stopgap measure, keeping the trains running.

Wednesday’s state budget deal, which ended a monthslong funding impasse, did not include a funding fix for SEPTA.
