CTA Train Tracker
The CTA has launched its CTA Train Tracker website, allowing riders to use their computers and smart phones to view estimated arrival times for trains on all eight CTA rail lines.
The website provides estimated arrival times for trains at all 144 CTA train stations on all eight of the agency's rail lines. CTA customers can visit www.transitchicago.com and follow the link on the page to CTA Train Tracker. There is also a mobile version of the program for smart phones.
