After some tries to explain the outpost system i made in 0.16 i was glad that in 0.17 the settings per train were blueprintable.
i now had some time to made a fue changes and made a new blueprint book.
this is a book with a fue pre made stations with settings complete.
(A book with the lose modules is here https://factorioprints.com/view/-LcT-4IGP8aUer9_uIG4)
each station size (1-3-1, 1-5-1, 2-7-2, 3-13-3 wagons) has 3 station blueprints.
1 is the one time use for the BASE station,
2 is the BARE outpost station that will get the train called.
3 is the Full outpost station to place after the train is on its way. the train will then put bots in the system and build the rest of the station for you.
After this you can plop down any blueprint as long as the items are available in the train. The station will add bots if needed. When the bots are not needed ( build is finished) the system will also reduce the bots for you.
The fuel car and the fuel for the train it self will use the best fuel available in the system. When for some reason that fuel has run out. Both will switch back to a lower tier.
Also all normally used items are delivered to all Outposts. As soon you are in range of the bots and you low on belts. They will deliver the amount available in the Outpost and the train if available will come and top the Outpost off. If you're still there it will try like normal full fill all your needs
It is not needed for the expensive items (like reactors and so) to be unloaded in all Outposts but it's possible to put them on the train for when you need them
In the bigger train setups I included also the ingredients for artillery shells. They stack better then the shells themselves.
