The screenshots shown below give examples of how junction settings can be used to control the operation of a session.
Application 1: Presetting Junctions
1. The Scenario:
When a consist reaches a trigger, the junctions ahead are set and locked into position.
2. Rules Used:
- Trigger Check Rule to trigger the event.
- Set Junctions Rule to set junctions.
3. Session Rules Screenshot:
 |
4. Example Explanation:
- Line 1: Trigger Check The event is triggered when the consist reaches a trigger. This executes the following rule.
- Line 2: Set Junctions Sets selected junctions to set directions and specifies the level of control by the users and AI.
 |
Application 2: Asking the User to Set Junctions
1. The Scenario:
A consist has been halted at a trigger placed in front of a junction. The user will be asked to set that junction and the following junction before the consist can proceed.
2. Preconditions:
- Navigation Display Rule to create a navigation point set.
3. Rules Used:
- Wait on Navigation Point Rule to trigger the event.
- Message Popup Rule to open a message window on the screen.
- Multiple Junction Alignment Check Rule to test if specified junctions are set correctly.
4. Session Rules Screenshot:

5. Example Explanation:
- Line 1: Wait on Navigation Point The event is triggered when the consist halts at the navigation point assigned to the trigger. This executes the following rules simultaneously
- Line 2: Message Popup Displays a message window asking that the next two junctions be manually set.
- Line 3: Multiple Junction Alignment Check tests the switch directions of the next two junctions and waits until they are aligned as specified.

| Checking junction switch settings |
The following line is executed only if the junctions are set correctly
- Line 4: Message Popup Displays a message window stating that the junctions are now correctly set.
