Factorio city block reddit 2021 Note that there is no mall, and this requires the LTN mod to work properly, and all trains are RHD, 2 engines with 4 cargo cars. Then a block for the trains to come and go. I do exactly the same, I have a BP modular book and generally go for 1 iron 1 copper 1 stone yellow belt of furnaces, red green and military science + baby mall of belts, inserters, assemblers etc then add another iron and copper and start the mall and oil process but the "main base" doesnt get any additions after this. 4 i/o would have given small area but suppose if it needs 5 i/o then you take 1 from another block. Like two trains going through intersection from opposite directions both get rerouted to left turns at exact same time, or approach it for left turn at exact same moment. Circuit logic is not inherently required for city blocks. on the other hand, it also depends on what you mean by city block base. I've been playing Factorio since 0. Posted by u/Pzixel - 6 votes and 2 comments I used LTN to make a pretty simple city block base. While the approaches are similar, my 'blocks' are effectively divided into single-product cells. zwwiwgieaeietzbctdvxqkgygdagkcnfedfeuodapwppyhgzacaxbszggsztdcuqeqv
