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.
"I heard a boom and when I got off the train, the train was all the way up the escalator. It's a wreck," Denise Adams, who was riding towards the back of the train, said. "It was a lot of panic because it was hard to get people off the train."
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.
Steele said the cause of the accident remained under investigation. "We don't know yet what led to this incident ... We will be looking at everything - equipment, signals, the human factor, any extenuating circumstances," he said.
Steele did say the train was "apparently travelling at a higher rate of speed than a train would be" while pulling into the station and officials are trying to determine why. He said the US National Transportation Safety Board was also investigating.
The accident happened around 2.50am. "There is a stop down there for each track. There's three tracks there. The train actually climbed over the last stop, jumped up the sidewalk and went up the escalator," Santiago said.
More than 50 firefighters and paramedics responded, he said. "We did not know if there was anyone underneath the train ... so we brought in our specialised units to check underneath there ... They made a visual to make sure no one was underneath."
Six people were listed in fair-to-serious condition and 26 in good-to-fair condition, fire officials on the scene said. Nine were transported to Resurrection Hospital, eight each went to Our Lady of the Resurrection Medical Centre and Swedish Covenant Hospital, and seven went to Advocate Lutheran General Hospital in Park Ridge. All of the injured were passengers on the train, officials said.
Robert Kelly, president of Amalgamated Transit Union Local 308, which represents more than 3,500 CTA workers, said the operator suffered minor injuries to her leg.
The operator would undergo drug and alcohol tests as part of standard procedure, Steele said.
Initial inspections indicated that the front two carriages of the train were damaged as well as the escalator, officials said.
"Once we remove the train, we'll have a much clearer picture of what the issues are there," said Chris Bushell, chief infrastructure officer for the CTA.
While there was some structural damage to the platform as well, "the stairs look solid and the majority of the rest of the structure underneath looks solid".
Downstairs at the station, an annoyed customer approached crime scene tape and said he had a flight to catch.
An officer paused before speaking, with a slight smirk and dry delivery: "Well, a train derailed. It doesn't happen every day, sir."
