Train derails, climbs escalator at Chicago airport

By

CHICAGO (AP) — Authorities say they're looking into whether faulty brakes, signals or human error may have caused a Chicago public-transit train to jump the tracks and scale an escalator at O'Hare International Airport.

National Transportation Safety Board investigator Tim DePaepe said at a news conference Monday that officials will interview the train's operator and look at her routine over the last few days. She is still in the hospital.

The early-morning accident on the Blue Line injured 32 people. None had life-threatening injuries.

DePaepe also says there is video footage available from a camera in the station and one mounted on the front of the train.

The derailment happened just before 3 a.m., which helped prevent more injuries in an underground station that's usually packed with travelers.
