Wow it's all so clean. Where are you getting those lights, I haven't unlocked any I'm particularly happy with.
I can't wait to start again and have a plan going into everything, I've just unlocked the hoverpack and drones, so right after getting into the habit of spacing factories out rather than packing everything into as small a footprint as possible I've started flying around and lazily building into existing factories without planning. Last night I plonked down a supercomputer factory basically inside another factory, with the conveyors all clipping through each other, then I stuck a drone plaform on top, redirected some fuel to it and called it a day. No idea if it's even all working.
I've got 2 nights of work (security work, so 13h shifts including ~6h of downtime) before I can play again, so I think I'll sketch up some designs to tidy up my train system and redo a couple of areas before the mess gets too big. I keep detailed spreadsheets of every station and which platforms load & unload what on to which trains, as well as a separate sheet with each train, the time table and cargo loads/unloads. Trains have definitely been my favourite mechanic so far.
