This command sets the train to autopilot mode. The driver will obey all signals but doesn't change junctions. It is the user's responsibility to set the correct path. To use the command it must be added to the Driver Command Rule in Surveyor.
The command has two options:
- activate:
Activates the autopilot on a train. The train runs forever, the only way to stop it is to abort the command.
- stop at trackmark:
The train drives until it reaches a selectable trackmark. When the trackmark is reached the next command is executed (or the train is stopped).
When the command is used in conjunction with the autopilot rule it is possible for drivers to leave trains which have autopilot enabled. The rule will remember the state of the autopilot even on unattended trains and keeps them running. If a driver returns to an autopilot train the command is added to the schedule again.
