Derailment video posted online
New surveillance video appears to show the moment of impact when a Chicago Transit Authority train careened past the end of the track and up onto an escalator at O’Hare International Airport.
The surveillance video, taken from one of the more than 40 cameras at the station, shows two people jump out of the way as the train heads up the escalator.
NTSB officials told ABC affiliate WLS the train was going 25 or 26 miles per hour when it pulled into the O’Hare station early Monday morning.
Lead investigator Ted Turpin said the that was normal speed for entrance.
What isn’t clear is how fast the train was going when it derailed at the end of the platform and why an automatic emergency braking system didn’t stop it.
NTSB investigators said they spoke with the train’s operator, who was one of 32 people treated and released from a hospital on Monday, for about two hours on Tuesday.
NTSB officials would not comment on the interview.
Chicago Transit Authority union officials said Monday she may have “dozed off” at the controls as the train pulled into one of the world’s busiest airports.
