Dramatic footage believed to be from the moment a train derailed at Chicago O'Hare International Airport on Monday surfaced on YouTube Wednesday.
The alleged CCTV footage shows a man walk up an escalator and begin speaking with a person who appears to be an airport official. As they converse, the train grows closer and closer until it barrels up the escalator, damaging everything in its wake as the two scurry out of its way.

The Blue Line train derailed early Monday morning. More than 30 people were injured in the crash, but none seriously.
Reports from the Chicago Tribune claim that the train was going faster than it should have as it pulled into the station, and that the driver might have dozed off right before the accident.
