About 300 passengers on a commuter train heading to Philadelphia had to evacuate after an electrical problem caused lots of smoke during the morning rush.
The Reporter news site reported the SEPTA Regional Rail train started smoking around 7:30 a.m. Thursday as it was stopped at the North Wales station, about 25 miles northwest of the city.
Southeastern Pennsylvania Transportation Authority General Manager Jeffrey Knueppel, who was on board the train, said it was likely a traction motor issue.
