i am new to the Factorio Forum and want to share my combinator based supply train setup with you:
What does it make different to other smart train set ups?
1. It uses no mods at all
2. handle all items your outposts will ever need in just 1 supply train
3. maintain different and independent robotic networks
4. even if you dont understand combinators, you will find this setup very easy to use
5. no mindblowing and complicated contraptions!
This setup comes with different modules to help you maintain your outpost and defensive lines
Module 1: The Depot
Module 3: The Logistics Network
The System itself takes some time to run smoothly, depending on how many items your outposts need at a time.
If you want to fill your outposts from 0, then you need some patience as the train will grab a bulk of different items and then starts to deliver them until an item is no longe required. If all your outposts have the desired items, the train will supply them much faster, as only ammo, repairkits and such are needed.
If no items needed the lamp will turn red and the train will wait until green light

Thanks and have fun
