CHICAGO — A power outage caused disruption to North Side CTA "L" train service Tuesday evening, officials said.
Power was restored about 30 minutes after Red, Yellow and Purple line trains were stalled about 5:30 p.m. after switching problems at the Howard Station caused by a power outage, according to the Chicago Transit Authority.
Red and Purple line trains faced major delays as they resumed service about 6 p.m., according to the CTA.
Service on the Yellow Line was restored just after 6:30 p.m. and also faced residual delays.
The Chicago Transit Authority said riders should allow extra travel time, and suggested the No. 22, 36 and 151 lakefront bus routes as alternatives to Red Line and Purple Line service.
