Notes: the Name of the Session is the Username tag entry in the config.txt file the Description of the Session is the Description tag entry in the config.txt file Both entries can be edited in the Session Editor and the config.txt file for the Session asset will be updated when you save the Session and exit Surveyor.

The order of the Rules in the Editor list is generally not important. All the rules shown will be executed simultaneously although some rules will take longer to complete than others

If the order in which some of the Rules are executed is important, then group them together in a Ordered List Rule (some are shown in the image).

Rules can be grouped together for convenience (e.g. all the Rules that set signals at the start of the Session) or because they depend on a particular event (e.g. a time, a train arriving at a set point, a wagon being loaded, etc). These form Nested Rules and are indicated by arrow heads as shown in the image. Click on an arrow head to open up its nested list of child Rules.



Each of the Rules that have been nested under the Ordered List Rule have been indented one level to the right.

More information on the various types of List Rules and how to create Nested Rules can be found on the Trainz Wiki Page at:-
