From the main view of Program, you can create and edit Tracks under  the Manage Tracks tab.

You can add a name and a picture for a Track.
Tracks are used to handle parallel program items, for example, if there are different themes for different parts of the day that run in parallel.

Tracks are added to the program at the time when the first program item in a track begins.
All program points that are added under a track are shown under that same track.
