How-to guide:
Bus Tracker by Text

CTA Bus Tracker SM can give you estimated arrival times by text message (works on most mobile phones*) with CTA Bus Tracker by Text.

You can get information online in advance of your trip, or find information on how to text at any posted bus stop! Let us know what you think at


Getting information in advance

Cheat sheet: Print out this page and jot down your favorite stops. (pdf)It's easy as 1-2-3:

  1. Find your stop ID.  (How do I find my stop ID?)
  2. Text ctabus [stopID] to 41411

    Be sure to text the word "ctabus", a space, and then the
     actual stop ID number, such as "ctabus 14624" (without quotes).
  3. Receive estimated arrival times.


*Important note: Message and data rates may apply. Check with your mobile carrier first. If you need help, e-mail us at

At the bus stop

Information about how to text for estimated arrival times from Bus Tracker are now appearing on all posted CTA bus stops. Simply look at the bottom of the bus stop sign for instructions:

Here's how the text message you send might look if you were going to catch a #53 Pulaski bus at Fullerton heading south (which stops at stop ID 14624). The bus stop sign at the stop will say to "Text ctabus 14624 to 41411 for estimated arrival times."

Try it!

Send ctabus 14624 to 41411, like this:

After your message is received, you'll get a message like this:

This example response says that, as of 5:07 PM, at stop 14624 (at Pulaski & Fullerton), Bus Tracker estimates that a #53 bus to 31st is due to arrive, and then another one should arrive in about 11 minutes

Additional Commands

Also, you can also reply to this message with "S" to get any service bulletins that may affect your trip (customer alerts), or "R" to get the latest, most updated result for the same stop.

If your stop has multiple routes serving it, your results may not fit in one text message. In that case, you can also reply with "N" to see the next result for the stop you requested.

If you have subscribed to receive text messages for service alerts or arrivals at scheduled times from the CTA Bus Tracker website, you can always reply with (or send a new text with) "STOP" to unsubscribe.

(Remember: Message and data rates may apply. Check with your mobile carrier first.)


Narrowing your results

To get just the routes you're interested (and potentially reduce the number of texts you need to send or receive to get the information you want), you can also specify a route number in your request. Add "rt[#]" (with the route number instead of the number sign) to your request.

ctabus 1124 rt26

Instead of getting all results for buses predicted to arrive at stop 1124 (Michigan & Ontario), you'll only get results for #26 South Shore Express buses.
