Breaking News: 32 Hurt After Chicago Train Derails At O'Hare International Airport Subway Station

More than two dozen people were hurt, none seriously, after a train derailed inside a Chicago subway station early Monday, authorities said.

About 32 people suffered minor injuries after the runaway train vaulted over the platform edge and launched up a pair of escalators that lead to O’Hare International Airport shortly before 3 a.m., authorities said.

“The train actually climbed over the last stop, jumped up on the sidewalk and then went up the stairs and escalators,” Chicago Fire Department Commissioner Jose Santiago told WMAQ-TV 

It wasn’t immediately clear what caused the wild wreck, but Santiago said officials were speaking to the train’s operator.

Brian Steele, spokesman for Chicago Transit Authority, told reporters that investigators were also reviewing footage from surveillance cameras and noted that the National Transportation Safety Board had been notified.

“It appears as though the train would have been going faster than a train normally birthing at this station would be,” Steele said. “Normally a train pulls in at just a couple miles an hour and pulls into the station. Obviously, this train did not stop, so speed could be a factor here.”

The victims were all taken to local hospitals, where they were treated for injuries that included bumps, bruises,and neck and back pain.
