A blueprint book for creating automated trains as described in this video from Steejo: https://youtu.be/JN50L6RLcm8
There are four components needed for these blueprints to work: The Staging Station, Holding Station, Ore Depots and Ore Outposts.
The Staging Station contains the logic to ensure that multiple trains do not goto the same location.
The Holding Station is where trains refuel and wait for the Staging Station to be free. The train with it's required logic is on the Staging Station blueprint.
The Ore Depot is where ore will be delivered do. It must be connected via green wire to the Staging Station. Connect it from the Ore Depot's big electric pole to the Staging Station's big electric pole.
The Ore Outpost is where ore is mined. It does not need to be connected to any other station via logic circuits The blueprint is designed to set the station priority based on how full the depot is so that trains will goto the fullest Outpost's first.
