FAIRFIELD, CT -- Officials investigating a train collision in Connecticut have ruled out foul play and are studying a rail fracture where a derailed commuter train was struck by another bound for New York City.
National Transportation Safety Board member Earl Weener says the broken rail is of substantial interest to investigators and a portion of the track will be sent to a lab for analysis.
Weener says it's not clear if the accident caused the fracture or if the rail was broken before the crash. He says he won't speculate on the cause of the derailment.
Seventy-two people were sent to the hospital Friday evening after a Metro-North train heading east from New York City derailed and was hit by a train heading west from New Haven.
