If you are using a portal to spawn trains, then go into Surveyor mode, load in the layout and session.
Click on a portal and the setup comes up.
For each train to be randomly generated you can assign a certain set of commands for it.
When the train consist is spawned and comes out of the portal the assigned order commands would show.
Autopilot is a command that needs to be enabled in the session before entering the data in portal.
To do this:
Click on Edit Session Rules
Open up Driver Commands
(Specifies which commands will be available to players in Driver mode).
Check (tick) the Autopilot Command
When click open the portal setup the session autopilot icon should be available to use for any AI driver you wish.
Happy Trainzspotting
