For years, our idea of tracking the train was sticking our frozen necks out, looking down a track, and waiting for headlights to appear in the distance. Thanks to the CTA Train Tracker, we've gained some technological ground. Those familiar with the CTA Bus Tracker will appreciate the Train Tracker's simplicity. Pick a line, pick a stop, plan your route. While it can't get the train to you any faster, it can tell you approximately how long you'll be huddling under a heat lamp with your fellow travelers.
