BRIDGEPORT - It has been one week since a Metro-North train derailed in Bridgeport just east of the Fairfield Metro-North station, hitting a train on another track.

First responders who were at the scene say they were most concerned about the more than 70 people who were hurt in the incident. Some tell News 12 Connecticut that they were shocked when they saw the scene, but their training kicked right in.

"It was almost reminiscent of the people kind of walking in a haze of Sept. 11, you saw people clearly shaken and trying to find where they needed to get to," says Assistant Chief Christopher Tracy, of the Fairfield Fire Department.

Train service was disrupted for several days.

Officials say they are still investigating the cause of the crash.
