At least 60 people were injured, five of them critically, in a head-on, rush-hour collision between two commuter trains Friday evening near New York City, officials said.
Metro-North Railroad described it as a "major derailment", just outside Bridgeport, the most populous city of Connecticut state in the US.
About 250 people were on the trains involved in the crash, BBC reported, adding no fatalities had been reported.
The accident occurred around 6.00 p.m. after a train which left New York City's Grand Central station en route to New Haven, Connecticut, derailed and then was hit by another train, said officials.
