CHICAGO, Sept. 30 (Xinhua) -- Thirty-three people were injured Monday morning after two trains running on the Blue Line tracks collided at a station in northwest Chicago.
A Chicago Transit Authority (CTA) official told Xinhua that the 33 people suffered minor injuries and were transported to hospitals.
The accident happened at around 8 a.m. local time when an outbound train stopped at Harlem station was hit by an out-of- service train going the opposite direction on the same track. There were no passengers on the out-of-service train.
The CTA official said CTA Blue Line has resumed service by bypassing Harlem station and using only one track at the station.
The CTA was investigating the case, the official said.
