CHICAGO (STMW) — Blue Line trains between O’Hare and Rosemont are operating on one track and shuttle bus service continues after a train derailed near the airport stop Tuesday afternoon.

At 4:47 p.m., a Blue Line train was leaving the O’Hare station when it derailed while going through an interlocking switch, CTA spokeswoman Catherine Hosinski said. Customers were safely escorted off and were able to make it back to the O’Hare platform, she said.

As of about 7:30 p.m. Blue Line trains in both directions started operating on one track while shuttle bus service continues, Hosinki said.

Fire Media Affairs Director Larry Langford said a female passenger suffered a minor shoulder injury and was taken to an area hospital in fair to serious condition. There were no other reports of injuries, he said.

Langford said the derailment happened about 1,000 feet from the O’Hare station, within a tunnel.
