The following video shows the creation of a Breach Line Rule, using an existing Breach Line (please see Breach Lines | Video) and a track breaking this rule. In this scenario, the Breach Line is set to notify you if a track moves across the breach line towards the orchard, and the broken rule triggers an alarm. The track is then permitted to move back across the breach line without notifying you and the alarm stops:
