Metro-North Trains Collide in Connecticut, 20 to 25 Injured

Two Metro-North trains collided in Connecticut after a “major derailment” during the evening rush hour tonight, causing at least two dozen injuries and massive delays on the New Haven Line, Metropolitan Transportation Authority said.

The accident happened about 6:10 p.m. just east of the Bridgeport-Fairfield line when a westbound train from New Haven derailed and collided with an eastbound train on a section of track near a viaduct that is under renovation.

20 to 25 people were injured, Fairfield Police Officer Matt Panilaitis told The Associated Press. He said there were no fatalities.

An MTA rep said there was no eastbound service on the New Haven Line east of Bridgeport as of 7:30 p.m., and that trains from Grand Central Terminal would only run as far as South Norwalk.

The accident occurred on a stretch of tracks undergoing repairs, with only two of the four tracks in use, forcing trains to pass each other on adjacent tracks.

Photos taken at the scene showed a train car askew on the rails, with its end smashed up and brushing against another train.

"At this stage, we don't know if this is a mechanical failure, an accident or something deliberate," Fairfield police spokesman Lt. James Perez told the Connecticut Post.
