More than 100 people suffered minor injuries this morning when a Long Island Rail Road train derailed at the Atlantic Terminal in Brooklyn, New York. According to the New York City Fire Department, all reported injuries are non-life threatening, with patients being characterized as “walking wounded.”

One passenger told WNBC that they heard a loud boom, then the train doors opened. “I don’t know, all I remember is being on the floor,” a woman said.

According to ABC Eyewitness News, at least one source said that the train was going too fast as it entered the station and struck the bumper at the end of the track.

Approximately 600 passengers were on the train at the time of the accident. One witness described the scene as “total pandemonium,” with people screaming, crying and panicking.

New York Gov. Andrew Cuomo said that compared to the Hoboken train accident, this crash was a “relatively minor accident,” but promised a full investigation.

Twitter images showed the train tipped at an angle.
