How to Control Junctions in Sessions

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.

Junctions can be controlled by Session Rules during the running of a Session The level of control includes:- locking junctions (all or some) against user control setting junctions according to decisions made by users checking to see if users have set junctions correctly

The following applications give examples of using Session Rules to control junctions.

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:
	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 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
