CHICAGO — Normal service was being restored on several "L" train lines after about 90 minutes of "major delays" Tuesday, officials said.
Brown, Green, Orange, Purple and Pink Lines had delays averaging 10 minutes due to switching problems in the Loop about 3:22 p.m., according to the Chicago Transit Authority.
The longest waits were on the Green and Pink lines, which had delays of 14 and 16 minutes, respectively, a spokeswoman said.
Normal service was being resumed about 4:45 p.m., but trains were still experiencing residual delays during the evening rush hour, the CTA said.
It was unknown how long residual delays would last across the five lines, the spokeswoman said.
