This session is for the route Bi-directional AI using ASB.
The session configures the triggers and AI train portals. It can also be used as a template for other sessions.
In general, give priority to the AI. In crossing loops the AI will always take the right track.
Four rules must be followed when driving the player train.
1. The switches with tall switch stands must be returned to the straight through setting if the setting has been altered for switching purposes.
During switching operations
2. If the player train runs forward over the switch leading to the single track, then it must continue moving forward until the last vehicle passes the signal protecting the entry to the loop.
3. If the player train runs past the box with red and green lights standing to the right of the track in the single track section, then the train must proceed onwards into the next loop.
4. If the player train moves through the section of track between the Limit of Shunt signs, then the train must continue on until all the vehicles have cleared the signs.
Providing the player train has passed the box with red and green lights before an oncoming AI train in a loop passes the signals allowing it to enter the single track section, the AI train will stop and allow the player train to continue onwards and enter the loop.
Either watch the AI operation, or drive the player train around the loop, or take the left diverge in front of your locomotive and collect all the freight cars on the route before returning to the spur where you started. This should take about 45 minutes.
AI trainz will be generated by the portals at approximately 10 minute intervals.
