Trains on the Chicago Transit Authority's Yellow Line resumed service Tuesday evening, about four hours after a minor derailment in the north side Rogers Park neighborhood.
One wheel of one train came off the rail at about 1:40 p.m. as the train was approaching the Howard station at 7519 N. Paulina St., according to CTA spokesperson Catherine Hosinski.
Three passengers on the train were moved to the front of the train and assisted onto the platform. No injuries were reported.
Service was suspended on the Yellow Line after the incident and shuttle buses were made available for transit in both directions. The Route 97 Skokie Bus was also available as an alternative, Hosinski said.
The derailment caused some delays on Red and Purple lines. Yellow Line trains were operating with residual delays at about 5:30 p.m., according to a post on the agency's Twitter account.
