Sounds cool; I like the premise. Sounds like hell to actually play tho lol

Oh, no doubt. :) But sometimes a crazy challenge is fun BECAUSE it's so crazy. (Or maybe I'm a masochist.)

It's a fun challenge. I did it once, but stopped due to lag from SO MANY TRAINS. Want to do in again in 0.15. -- No Belts, no "Logistic Systems" and no inserter chains -- Means you use long inserters or do assembly completely in a train loaded with precise ratios.

With the new fluids stuff I'm going to try for very few pipes as well!

Will definitely use this mod when I do. Won't need to bootstrap myself with it!

I might actually consider this for a playthrough lol. I can sort of imagine some things with trains... previously I had considered putting all my science packs onto trains and ferrying them over to a specific science area, but the actual implementation would have been tricky and more expensive than it'd be worth.

Might need some train circuit.. stuff to make it work effectively though =P
