On June 25, the CTA experienced major delays on the Blue Line during morning rush hour because of a power outage. The Blue Line has been affected by more than a dozen delays in June for a variety of reasons, including door and mechanical problems. RedEye rounded up the delays in the form of tweets by the CTA. A spokeswoman for the CTA said the Blue Line has made 8,700 trips so far this month and the delays represent a fraction of 1 percent of the trips. "While delays are unfortunate, largely, they have been minor," CTA spokeswoman Tammy Chase said.
