SEPTA's Fox Chase Regional Rail line had been suspended for the Wednesday evening rush hour after a man was struck and killed by a train shortly after 4:30 p.m., the transit agency said.
Service on the Fox Chase line resumed just before 7 p.m. as the police activity cleared, SEPTA said in a tweet.
The 18-year-old man was walking on the tracks near the Lawndale Station when he was hit by an oncoming train, Philadelphia police said. He was pronounced dead a short time later.
SEPTA said it was unclear why the man was on the tracks.
