A Chicago Transit Authority train car rests on an escalator at the O'Hare Airport station after it derailed on March 24, 2014, in Chicago.
Chicago:
An eight-car Chicago commuter train plowed across a platform and scaled an escalator at an underground station at one of the nation's busiest airports early on Monday, injuring 32 people on board, officials said.
No one suffered life-threatening injuries in the Blue Line derailment at O'Hare International Airport, Chicago Fire Commissioner Jose Santiago said during a morning briefing.
Chicago Transit Authority investigators along with the city fire department and police were reviewing security footage and interviewing the driver and other CTA workers to pin down the cause of the accident around 2:50 a.m. The National Transportation Safety Board has been notified.
Steele said crews were working to remove the train and fix the escalator and aren't sure when the station will reopen.
The train appeared to have been going too fast as it approached the end-of-line station and didn't stop at a bumping post - a metal shock absorber at the end of the tracks.
"The train actually climbed over the last stop, jumped up on the sidewalk and then went up the stairs and escalator," Santiago said.
"Apparently (it) was traveling at a rate of speed that clearly was higher than a normal train would be," Steele said.
It wasn't clear how many people were on board at the time of the crash, but that it took place during what is "typically among our lowest ridership time," Steele said.
