Alriiiiiiiiight. So, after building a full logistics map for the upcoming factory, I've decided this is where I need to fork off a new branch of tubeway, to head off into the distance.

That should do it.

A little more brainstorming, and this is what I came up with for a floor layout.

First machines to get routed and built are the Copper Ore Miners.

Then it's a few Water Extractors and a looooooot of Refineries.

Finally for today, that should cover logistics for all the Refinery inputs.
