One person was taken to a hospital after a Brown Line CTA train hit a car that was on the tracks Thursday afternoon on the Northwest Side, according to officials.
About 2:35 p.m. a Loop-bound train that was leaving the Rockwell station, 4648 N. Rockwell St., hit a car that was on the tracks, said CTA spokeswoman Catherine Hosinski.
