UPDATED: 6:39 p.m., Wednesday:
Regional Rail service resumed around 6:35 p.m. but was expected to have extensive delays throughout Wednesday evening, according SEPTA.
WHYY reporter Jim Saksa tweeted that a SEPTA spokesperson said a loud bang related to an equipment failure was heard on a train stopped between 30th Street Station and Center City. Passengers panicked once they heard the noise and left the train.
SEPTA Regional Rail trains that run through Center City in Philadelphia were stopped Wednesday evening during rush hour.
SEPTA officials said the stoppage of trains was due to an “emergency evacuation” and “police activity.” As of 6:20 p.m., full details were not immediately available and the train stoppage remained.
Images on Twitter showed groups of people walking along the tracks in Center City. A LevittownNow.com reader who was commuting to work said little information was available on the train, but they spotted SEPTA police officers walking along the tracks.
Delays throughout the evening were expected.
