The information in this Wiki Page applies to TANE, TRS19, Trainz Plus and TRS22. It gives examples of how junctions can be controlled using Session Rules.

Application 1: Presetting Junctions

	The Scenario:
	When a consist reaches a trigger, the junctions ahead are set and configured (e.g. locked/unlocked, AI control allowed/disallowed)

Rules Used:

	Trigger Check Rule to trigger the event
	Set Junctions Rule to set junctions

	Session Editor Screenshot:

Description:

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

For example:-

Application 2: Asking the User to Set Junctions

	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

	Preconditions:
		Navigation Display Rule to create a navigation point set

Rules Used:

	Navigation Display Rule to create a navigation point set (in Preconditions above)
	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

	Session Editor Screenshot:

Description:

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
