Red Line riders this evening saw big delays due to track problems north of the 79th Street station.
The Tribune reports that at 4:15 pm an operator noticed the track problem. This caused trains in both directions to share a single track as crews worked to repair the problem. As of 8 pm repairs and single-tracking were still in progress.
A neighbor reported waits of at least 30 minutes to board a train.
