Southbound Blue Line trains are operational again following a derailment Thursday evening between the Pulaski and Austin stations.
CTA officials say a train leaving the Cicero station hit an automobile tire on the tracks shortly after 8 p.m.
The impact caused the front wheels on the train to come slightly off track. NBC 5 has learned the tire flew off a tractor-trailer on the adjacent Eisenhower Expressway.
It’s unclear how many passengers were on board, but there were no reports of injuries, Steele said.
Shuttle buses transported passengers between the Pulaski and Oak Park stops while the train was moved back onto the track.
A single track is in use southbound between the Pulaski and Austin stations, but CTA officials said service should to be fully restored by the morning rush hour.
