(Chicago, IL) Surveillance camera footage has emerged of a subway train going out of control, off track and up an escalator!

More than 30 people were hurt when the Chicago Transit Authority train went off the rails.

The eight-car train failed to stop at the end of the line when it arrived at the airport station at 2:52 a.m., a Chicago Fire official said.

The lead car appeared to have climbed an escalator adjacent to the passenger platform.

“I’ve investigated many accidents and trains do different things,” National Transportation Safety Board investigator Tim DePaepe told reporters. “It’s all about kinetic force. I have not seen an accident like this personally.”

NTSB experts will examine video from station cameras and one on the front of the train for clues to the cause of the crash, DePaepe said.

A union official told reporters Monday that the train’s driver may have fallen asleep, CNN affiliate WLS reported.
