Reddit factorio city block It is up to you how to do it. I don't care about compactness so I would use my chunk-aligned station BPs and the result would be as big as three city blocks. My basic block is just big enough for a 1+1 train station on each of the 4 sides, since that's plenty for most space productions, but the blocks along the "X and Y axes" have longer sides that can fit two 1+1 stations, and the center block can fit two stations on each side. Usually, you use the starterbase which carries you to about the midgame and is generally used to fire the first rocket, to prouce enough materials to build your City Block design. I just spent a couple of weeks playing around in sandbox + editor mode designing my city blocks. Most city block designs around here are using huge blocks. You'll need to decide how many stations you can fit inside the block. Last but not least, I'd treat the city block as it's own factory. Instead design in mind with up to 1-2 belt of items in/out per chunk of city block length. That's a radar every 7 chunks, or I think 224. yhowhgiucehchwtjulkopmygxomdaywaqlgdlqntpwbfzbboioxfjbvxtzwnsglqapmdacokp
