On parts of the Brown Line, trains will be running on a single-track.
If you are riding the CTA's Red or Brown lines this weekend, you can expect delays. Crews will be doing maintenance work on tracks. On the Red Line, south-bound trains normally running through the subway between the Fullerton and Cermak-Chinatown stations will be re-routed to the el tracks Saturday and Sunday. Other trains will be re-routed to the Purple Line.
