30 hurt as train derails and shoots up escalator at Chicago airport
Cause of accident in Chicago unclear but speed may be a factor, transport official says

More than 30 people were injured when a Chicago commuter train jumped the platform and climbed up an escalator at O'Hare International Airport early yesterday, officials said.

Fire crews scrambled to determine if anyone was underneath the train but no one was found, according to Chicago Fire Commissioner Joe Santiago.
All of the injured were aboard the train and were taken in fair or good condition to four hospitals, he said. The operator of the train "was walking and talking as we were investigating", Santiago said.
The eight-car train was wedged near the top of an escalator used by commuters at the Blue Line terminal. Chicago Transit Authority (CTA) spokesman Brian Steele said workers may have to cut up the carriage and remove it piece by piece, which could take 12 to 24 hours. Then the damage would have to be assessed and repairs made before trains use the station, he said.
In the meantime, shuttle buses will replace trains for users of the rail line.
