Service on the Chicago Transit Authority's Red Line trains has been switched back to its familiar subway tunnels late Tuesday after a damaged third rail in the South Loop led to a re-route on elevated tracks.
The morning rush is not expected to be affected, according to CTA spokesman Brian Steele.
A portion of the rail became damaged between the Roosevelt and Harrison stations at about 7 p.m., Steele said.
While southbound trains were allowed back into the subway, northbound trains were run on the elevated tracks from the Fullerton to the Cermak/Chinatown stations, as crews spent three hours repairing the damaged portion of rail, Steele said.
The cause of the damaged rail remained unknown late Tuesday.Copyright © 2015, RedEye
