Connecticut Gov. Dannel P. Malloy says a total of 60 people have been taken to hospitals with injuries from a collision between two New York-area commuter trains.
The governor said from the scene of the accident Friday night that most people were not seriously hurt but five were critically injured, including one very critically injured.
No fatalities were reported following Friday evening's collision near Fairfield on the Metro-North Railroad.
The rail line referred to it in a news release as a "major derailment."
A spokesman for public safety officials in nearby Bridgeport says about 250 people were on the two trains that collided after one derailed.
The railroad says a train that departed New York City's Grand Central station en route to New Haven derailed. A westbound train on an adjacent track then struck the derailed train.
Some cars on the second train also derailed as a result of the collision.
Amtrak suspended service indefinitely between New York and Boston.
The governor said there was extensive damage to the train cars and the track, and that the accident will have a "big impact" on the Northeast Corridor. He said it could take until Monday for normal service to be restored. He said the area where the accident happened was down to two tracks because of repair work.
