The CTA is rolling out updates to how train tracker signs display information, adding customer alert information among other changes.
Signs are being tested in a variety of station types (island platforms, side platforms, multi-route) at these stations:
- Merchandise Mart (Brown, Purple Lines)
- Western (Brown Line)
- Grand (Blue Line)
- Grand (Red Line)
- Lake (Red Line)
- Washington (Blue Line)
- Randolph/Wabash (Loop ‘L’)
- Garfield (Green Line)
- Morgan (Green and Pink Lines)
- Clinton (entrance-only, Green and Pink Lines)
For example, this short video shows a sign with alert information:
And here's a sign at a Loop station serving a number of rail lines. This screen shows up to the next two arrivals for each route serving this platform, while holding the first row so it's clear what train is coming next at all times:
And, as the CTA says on its Train Tracker Screen Update page, here's "even more detail:"
If you really want to know what some of the new abilities are in full, technical detail, here's a more thorough run-down of some of the fine tuning we'll have at our disposal:
All signs will begin to show events affecting service (planned or unplanned) while service is affected--you'll start seeing this on signs sooner than some of the more specific, fine-tuning we'll talk about on this page.
Rows of arrivals on signs will be shown with a number so it’s clearer whether what your seeing is one of the very next arrivals, or trains that are a little further out.
Platform signs, in many locations, will continually show the next two trains to arrive at the platform/track where the sign is placed.
Platform signs that are shared between tracks or lines will scroll through just the next two or three trains in each direction, so the train you’re likely to board will appear more frequently.
Signs at entrances that lead to multiple platforms will show the most imminent arrivals a little longer than subsequent ones, but still show trains a little further out so you know whether or not you need to hurry or can grab a cup of coffee.
Signs specific to a single track, when showing more than just the next two arrivals, may “hold” the first row and/or show the most imminent arrivals for a longer period of time (so the next service gets more screen time than information that isn’t as immediate).
