A commuter train at Chicago O’Hare International Airport has derailed, injuring 32 people, officials say.
The train came off the tracks, crossed a platform and travelled part way up an escalator at one of the busiest airports in the US.
None of the reported injuries are serious.
A spokesman said the train was likely to have been travelling too fast when it crashed in the early hours of Monday.
"I heard a boom and when I got off the train, the train was all the way up the escalator," passenger Denise Adams told the Chicago Sun-Times newspaper.
Fire officials told the Chicago Tribune that six people were in fair condition and 26 in good condition as they were transported to hospital.
Investigators are said to be reviewing security footage and interviewing CTA employees to determine the cause of the derailment.
People posted images of the derailed CTA Blue Line train on social media.
