CHICAGO, March 24 (Xinhua) -- More than 30 people were injured when a commuter train derailed Monday morning at the underground station of an airport in U.S. midwestern city Chicago.
The accident happened around 2:50 a.m., when the CTA train jumped the platform and scaled an escalator at the Chicago O'Hare International Airport. None of the injuries were considered life- threatening.
The eight-car CTA train remains wedged near the top of an escalator used by commuters at the airport's Blue Line terminal. Workers may have to cut up the car and remove it piece by piece, which could take 12 to 24 hours, according to CTA spokesman Brian Steele.
All of the 32 injured were aboard the train and were taken to four hospitals, officials were quoted by Chicago Tribune as saying. Six people were listed in fair-to-serious condition and 26 in good- to-fair condition.
Blue Line Service to the O'Hare International Airport will be disrupted for most of the day. The cause of the accident remains under investigation.
