CHICAGO – Authorities have reopened the train station at Chicago’s O’Hare International Airport after a nearly four-hour shutdown to investigate a strong odor.

The station platform was evacuated Thursday morning. The Chicago Fire Department responded with a hazmat crew to check out reports of an ammonia-like odor in the track area.

Crews determined the odor came from cleaning products workers were using in an airport parking garage above the station.

Fire Department spokesman Larry Langford says the runoff came into the station’s tunnel area. As a precaution crews had to do extensive checks of water, sewers and other parts of the facility.

The Chicago Transit Authority used shuttle buses to bypass the closed Blue Line station.

CTA spokeswoman Lambrini Lukidis is confirming that the O’Hare station has reopened.
