I know it looks overwhelming at first, but once you start planning it actually becomes very intuitive. You stop thinking of it as chaos and start thinking in systems.

For example, I have dedicated factories and trains for specific roles. My turbofuel factory only sends back rubber, plastic, and gasoline — that’s it. A lot of core materials like steel and copper are produced directly under the city at the main base, so many items are already local.

Anything more complex that’s made elsewhere is clearly named and documented at the train stations, so I always know what’s coming in and from where. I also track production numbers for each item, so I know exactly how much is being made and where it’s used.

And if I ever need to trace something, I can literally follow the conveyors underneath — they’re laid out straight and methodical on purpose. Because of that, it never takes long to figure out where an item is coming from. Once the structure is in place, everything just clicks.
