Reminder: if you want to modify an existing plan that is in use or in production ("Active" or "Completed" status), first duplicate it (to do this, refer to the "Duplicating a transport plan" section of this article) and apply the modifications to the duplicate then publish it.

To create a new destination sign, go to your transport plan view (Resources > Transport plan) then click on the 'Lines' tab and select the line you want to create. Select the service and then the route by clicking on its identifier to be able to modify it.

Click on the blue icon with a pencil at the top right of your interface to modify it, then use the dedicated field to name your destination sign. Finally, click on the blue icon with a tick to save your changes.

You need to repeat the process for each race.
