Rules can set basic parameters in a Session including which driver is in each Train, the weather state, control method, set up industry dependencies, what Driver Commands are available in the Driver Module and set the time and time rate. They can also be combined, so that when a particular train hits a trigger the weather may change or a sound may be played. Then there is the ability to pull HTML pages and sound files into the game. On top of that the Rules can be arranged to occur in a particular order.

The Outdent, Indent, Promote and Demote commands are used to order the Rules in a Hierarchical and Ordered fashion. Some rules require indented child rules immediately below them.

The child rules can be re-ordered by using the “Promote” and “Demote” buttons to alter the order in which they are executed.
