Metro North

Metro North: Jeremy Grimes, a daily commuter from Connecticut shot this video, which shows passengers barely noticing a wide open door on a speeding Metro-North train. Even those a few inches from the open door (and the rushing ground below it) don't seem worried.

The malfunctioning door was left open as the train sped toward Grand Central Station.

"The train started to move and everyone just kind of acknowledged it, eyeballed it for a second and then shrugged it off," Grimes wrote in an email to the New York Times.

Metro-North officials were far more concerned.

"The footage in this video is very disturbing to us, and Metro-North is investigating," Metro-North spokeswoman, Marjorie Anders told the New York Times.

Freezing cold temperatures throughout the New York region have caused problems with motors and brakes on several Metro-North trains. Many of the railroad's older trains are awaiting repairs for damage caused by the winter chill.
