A sensor for an automatic braking system was too close to the end of the track to prevent a crash at Chicago’s O’Hare International Airport, according to a preliminary federal report released Monday.
The National Transportation Safety Board’s one-page analysis of the dramatic March 24 crash at the airport’s underground station said the Chicago Transit Authority train was traveling at 26 mph when it passed a “trip stop” that activated the emergency braking system.
“Due to the train speed, the distance from the fixed trip stop to the track bumper post was too short to stop the train,” according to the report.
More than 30 people were injured when the train slammed into the bumper at the end of the line, hopped onto the platform and scaled an escalator, causing $9.1 million in damage. Authorities have said the timing of the crash, which happened just before 3 a.m., limited the number of injuries because so few people were on the typically busy platform and escalator.
