Living downtown has just gotten a bit easier. The City of Chicago has finally caught up with the rest of the world and has unveiled the CTA Train Tracker.
Simply choose your line and your stop and the site will give you ETAs for all trains (both directions, all train lines).
NBC5 had a special report on Saturday’s 10pm news. Estimated arrival times trended later than trains arrived (Translation: Arrive 2-3 minutes before the ETA and you should be fine.)
The Mobile App has not yet been updated to include Train Tracker but a mobile site exists http://www.transitchicago.com/mobile/traintracker.aspx
