This feature is available for any transit type (buses, trains, trams, subways, ferries, and even cable cars ) that has GPS tracking installed. To use it, all you need to do is:

  1. Tap on the ‘Live Location” button on the Action Bar located at the bottom of the Itinerary, Line Details, or Station Details screens.
  2. A bus icon will be displayed moving across the map in real-time as it completes its journey, enabling you to view how much time is left until it approaches your stop. 

In addition, you can also see when the data was last updated (when the signal was last received from the vehicle), and receive service alerts for that line — all on the same screen.
