A commuter train heading from New Jersey to Philadelphia hit part of a downed utility pole during the morning rush, halting service and leaving thousands of commuters scrambling to get to work.
The Port Authority Transit Corporation train carrying 24 passengers hit the pole around 5:45 a.m. Monday in Camden, and service was completely shut down for more than three hours.
Four minor injuries were reported.
Transit officials say the utility pole appeared to have been hit first by a freight train on an upper track, leaving a section hanging over a wall and in the path of the PATCO train.
The 14-mile line serves about 38,000 riders daily. The shutdown created major traffic jams to and from the Ben Franklin Bridge between Camden and Philadelphia.
Some westbound trains began leaving from Broadway around 8 a.m. And by 8:45 a.m., PATCO had service in both directions going again between Camden and Center City Philadelphia.
All service between Ferry and Lindenwold remained suspended indefinitely.
The cause of the accident remained under investigation.
