Mining outposts designed for belt-based loading onto trains with high-ish mining productivity. Can theoretically output up to 24 blue belts (depends on shape/size of ore patch and current level of mining productivity) and will load 6 1-4 trains. The book is designed to shift+mousewheel between blueprints. See here for more: https://www.reddit.com/r/factorio/comments/u8ux1x/high_throughput_lategame_mining_outpost_up_to_24/
