It is the CTA's goal to put a digital display that features Train Tracker and CTA notifications in 143 stations in the next year, CTA spokesman Brian Steele said.
Two stations already have these displays: The new Morgan/Lake Green and Pink Line station on the Near West Side and the new Oakton station on the Yellow Line.
There are currently Train Tracker displays at "about 20" CTA stations, Steele said. They range from the large advertising displays at the Jackson Red Line station to the LED screens at the Belmont and Fullerton stops.
Eventually, all stations will have the displays like the ones at the Morgan and Oakton stations, Steele said. The CTA is installing the new screens at five northern Red Line stations that will close over the next few months for improvements.
Two stations, Granville, which recently reopened after renovations, and Morse, which is scheduled to reopen Friday, will get screens after the CTA receives them later this month, Steele said.
The CTA rolled Train Tracker out in 2011. Bus Tracker has been available for years, and some CTA bus stops feature Bus Tracker displays.
