Markers: 3 Types: Track Markers: Basically destinations you can set so the AI can go there. Sort of like a path marker for AI. Direction Marker: Tells what an track an AI can take. An AI will never take a track with the direction marker
facing against it. Priority Markers: Signifies to AI trains what track to take base on there priority which is set up in the session details. Triggers: Can do lots of things you can have certain trains trigger other train commands to go. Or have it trigger some session rule. Signals: The simplest way to say this is. You place signals which basically creates blocks and once a train occupies that block no other AI trains can enter.
