Local and federal officials will investigate what caused a Chicago commuter train to derail Monday morning, run over a platform and scale an escalator at O’Hare International Airport, injuring as many as 32 people.
No fatalities were reported, said Chicago Transit Authority spokeswoman Lambrini Lukidis to the Los Angeles Times. “They are all minor injuries,” she said. “From what I understand, none are life-threatening.”
Six people were listed in fair-to-serious condition and 26 in good-to-fair condition, fire officials on the scene said.
The eight-car Blue Line train was traveling about 2:50 a.m. when it ran through a bumper, according to the NTSB. The train then continued up the escalator.
Denise Adams, a passenger on the train, told reporters at the scene that she heard a loud noise during the impact.
“I heard a boom and when I got off the train, the train was all the way up the escalator. It’s a wreck,” said Adams, who was riding toward the back of the train. “It was a lot of panic because it was hard to get people off the train.
Adams said she was shocked to see the train cars stacked up the escalator. “The train is messed up, all the way up,” she said. “I was going to get on the first car, but I changed my mind.”
The National Transportation Safety Board announced it will investigate the accident. Separately, the Chicago Transit Authority said it, too, will investigate, Lukidis told the Los Angeles Times.
Service between Rosemont and the airport was down, Lukidis said.
However, trains continue to run between Forest Park and Rosemont, where passengers can catch a shuttle to the airport.
