Blue Line trains are running with residual delays after a derailment at the Harlem station Wednesday morning suspended service between Rosemont and Jefferson Park for more than two hours.
The CTA suspended service about 5:35 a.m. for the derailment. Trains were back up and running in both directions about 7:55 a.m., albeit on the same track, the CTA said. Normal service on both tracks resumed about 8:20 a.m.
