"All I know was I was in the air, hitting seats, bouncing around, flying down the aisle and finally I came to a stop on one seat. And I just gripped it because I felt the train sliding," Oliver told The Associated Press. "It happened so fast I had no idea what was going on. All I know is we crashed."
Oliver, a cardiology technician, was treated at a hospital for cuts and bruises and released.
Investigators Friday night did not know what caused the first train to derail. Malloy said there was no reason to believe it was anything other than an accident. The National Transportation Safety Board was sending a team to investigate.
"We're most concerned about the injured and ultimately reopening the system," Malloy said from the scene about three hours after the crash.
The governor said that most people were not seriously hurt. Among those critically injured, he said, one's injuries were "very critical."
The Metro-North Railroad, a commuter line serving the northern suburbs, described it as a "major derailment." Photos showed a train car askew on the rails, with its end smashed up and brushing against another train.
Malloy said there was extensive damage to the train cars and the track, and it could take until Monday for normal service to be restored. He said the accident will have a "big impact on the Northeast Corridor."
By late evening, Bridgeport Police Chief Joseph Gaudett said everybody who needed treatment had been attended to, and authorities were beginning to turn their attention to investigating the cause.
The Metropolitan Transportation Authority operates the Metro-North Railroad, the second-largest commuter railroad in the nation. The Metro-North main lines - the Hudson, Harlem, and New Haven - run northward from New York City's Grand Central Terminal into suburban New York and Connecticut.
