Vanilla Train Network by Haphollas is a fully automated train network to control all trains in the base. It functions somewhat like the mod "Logistic Train Network" but relies on circuits, magic and German engineering instead of mods. This is working for small and large bases and for modded and vanilla bases.
You can use this even without knowing how it works by simply using these blueprints for your stations, though I would highly recommend taking a look at my Tutorial video for explanations to get the full picture: https://youtu.be/v4VgZv35yUI
