Service resumes after SEPTA train derailment in Philadelphia caused major Regional Rail issues

Service was restored around 3 p.m. Wednesday, but residual delays are likely on multiple SEPTA Regional Rail lines after a train derailed at a major junction in North Philadelphia early in the morning.

The derailment happened around midnight at the 16th Street interlocking near the North Philadelphia station, a SEPTA spokesperson told CBS News Philadelphia. 

The train was stuck and disabled at the junction for several hours, but around 8 a.m., it was removed from the scene.

The Manayunk/Norristown, Fox Chase and Chestnut Hill East Lines were suspended while SEPTA worked to clear the junction. Those lines are now operating again but with delays, according to SEPTA.

Full service is also being restored to all other stations impacted by the derailment, SEPTA said.

There were 47 people aboard the train when the derailment occurred, and no injuries were reported.

The cause of the derailment is still under investigation.

Andrew Busch, a spokesperson for SEPTA, said there is no indication that the extreme heat played a role.

"When we do have this extreme weather, we reduce our top speeds because that's when you potentially have the damage with everything heating up, both on our overhead power lines and potentially with the tracks," Busch said.

Crews remained on the scene after the derailed train was removed and repaired damage to the tracks.

On Tuesday, service was suspended on the West Trenton Line in Bucks County after an unrelated freight train derailment near Feasterville, Pennsylvania.
