FOREST PARK, Ill. (AP) — Officials said nobody was at the controls of an empty commuter train that slammed into another train at a suburban Chicago station Monday, injuring dozens of commuters, but they don't know how the train got moving.
Video footage shows that nobody was driving the 4-car Chicago Transit Authority train as it rumbled the wrong way toward the train parked at the Harlem Avenue station about 10 miles east of Chicago. But investigators were trying to determine if it somehow started moving itself or if someone sent it on its way, intentionally or otherwise.
"If it wasn't a goof or there is someone not telling us something that creates a big problem because if one train can start moving without anybody doing anything than it can happen to another train," said Amalgamated Transit Union President Robert Kelly.
Kelly said he had never heard of a train simply starting to roll down the tracks. Not only that, but he said to start a train somebody would not only have to have a special key, but would have to know how to use it.
As many as four dozen people who were on the parked train were treated for minor injuries and released from hospitals, authorities said.
CTA spokesman Brian Steele said investigators are examing the video, the signaling systems and other data to determine what happened. He, too, said he had never heard of such an incident before. CTA spokeswoman Lambrini Lukidis said the video is being turned over to the National Transportation Safety Board, which took over the lead of the investigation.
What could make solving the mystery even tougher is that the train started its journey beyond the last station on the west end of the Blue Line that runs from the western suburbs, into the city and out to O'Hare International Airport.
