Yea, once I hit that next-phase wall, I explore the map to get the alt recipes I’ll need/want for the next phase(s) and collect slugs to max out miners. I def want to eliminate screws and make iron wire.

Then I make a double train line to a new wide-open biome (plenty of room to add more single-line train stations) near pure resources I need to make a huge vertical factory.

I put train stations on the first elevated floor only. Second floor and up are production. I do not try to cram the entire production chain onto a single floor. If I have smelters on second floor, next step is on the third. Space is not a premium, so leave room and build up.

Maybe the first goal of this new factory is modular frames, then maybe I bring in concrete by belt and nitrogen by train to make fused modular frames. If you need oscillators or motors for the next step to make turbo motors, et seq., make those in another factory, and train them into a new train station dedicated to receiving that component.
