Authorities still aren't sure what caused two commuter trains to collide outside Bridgeport, Conn., yesterday evening. An eastbound Metro-North train derailed and got hit by a westbound train on adjacent tracks, reports the Journal News. About 60 people were treated, and five remained critically injured as of this morning, reports AP. One of the trains was headed to New York's Grand Central Station, and the other was coming from there. The accident is expected to snarl train traffic, including Amtrak's, all along the Northeast Corridor over the weekend.
"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," says one 49-year-old female passenger. "It happened so fast I had no idea what was going on." (More train crash stories.)
