The CTA has started publicly testing a train-tracking system, which will allow riders to see when the next "L" trains are arriving.
The CTA Tattler reports wait estimates are popping up at stations around the system, including the Chicago stop on the Brown and Purple lines, the Fullerton stop on the Brown, Purple and Red lines, and the Polk stop on the Pink Line.
The CTA acknowledged the program's existence, but said the tracking information isn't ready for prime time yet, and didn't share many details about it.
The reason the public can see it right now, they said, is because the only way to test the tracking system is to have it up and running on the displays.
"This data is not constant but is being reviewed between rush periods and may appear intermittently on the displays," the CTA said in an e-mailed statement. "Personnel are still performing accuracy checks and making adjustments."
The CTA's bus tracker has been wildly popular, earning the title of second-most-googled-for thing in Chicago last year. A similar service would bring the "L" up to par with transit systems in Washington, London and Berlin.
There's no official launch date for the program, or a time frame the agency revealed, but keep your eyes on this space for updates as they roll in.
