# Station List ## Iron smelting * Iron ore dropoff * Iron pickup (2) * Steel plates pickup ## Copper smelting * Copper ore dropoff * Copper pickup ## Circuit mfg * Copper droppoff * Iron dropoff * Circuits pickup ## Refinery * Coal dropoff * Iron dropoff * Copper dropoff * Plastic pickup * Battery pickup * Rocket fuel pickup Coal goes to plastic. Iron goes to sulphuric acid and batteries. Copper goes to batteries. ## Adv circuit mfg * Copper dropoff * Circuit dropoff * Adv circuit pickup ## Alt-Adv circuit mfg (incorporates circuit mfg) * Copper dropoff * Iron dropoff * Plastic dropoff * Circuit pickup * Adv circuit pickup Downside: Adv circuits get less circuit supply because it has to share with the circuit buffer instead of taking from the circuit buffer. That could be avoided with a circuit network that favors advanced circuit production when a train isn't picking up circuits and the adv buffer isn't full. ## Processor mfg * Circuit dropoff * Adv circuit dropoff * Processor pickup ## Blue science * Iron dropoff * Steel dropoff * Circuit dropoff * Adv circuit dropoff * Engine pickup * Blue science pickup Iron goes to make miners and engines. Steel goes to engines. Circuit goes to miners. ## Black science * Iron dropoff * Steel dropoff * Copper dropoff * Coal dropoff * Black science pickup Iron goes to magazines, grenades, and turrets. Steel goes to magazines. Copper goes to magazines and turrets. Coal goes to grenades. ## Purple science * Iron dropoff * Steel dropoff * Stone brick dropoff * Engine dropoff * Circuit dropoff * Adv circuit dropoff * Purple science pickup ## Module mfg * Circuit dropoff * Adv circuit dropoff * Processor dropoff (optional) * Speed module pickup ## Yellow science * Copper dropoff * Battery dropoff * Processor dropoff * Speed module dropoff * Yellow science pickup ## Rocket control * Speed module dropoff * Processor dropoff * Rocket control pickup ## Alt-Yellow science (incorporates modules, processors, and rocket control) * Copper dropoff * Circuit dropoff * Adv circuit dropoff * Battery dropoff * Yellow science pickup * Processor pickup * Rocket control pickup ## Research * Red science dropoff (optional) * Green science dropoff (optional) * Blue science dropoff * Black science dropoff * Purple science dropoff * Yellow science dropoff * White science dropoff (optional) Research can be close enough to starting base for red and green science to be conveyed. ## Low density structure * Copper dropoff * Steel dropoff * Plastic dropoff * LDS pickup ## Satellite * Copper dropoff * Iron dropoff * Steel dropoff * Circuit dropoff * Processor dropoff * Battery dropoff * LDS dropoff * Rocket fuel dropoff * Satellite pickup Copper goes to solar panels. Iron goes to accumulators and radars. Steel goes to solar panels. Circuit goes to Solar panels and radars. Battery goes to accumulators. ## Rocket Silo * Rocket fuel dropoff * Rocket control dropoff * LDS dropoff * Satellite dropoff * White science pickup (optional) ## Alt-Rocket Silo (incorporates LDS and Satellite) * Copper dropoff * Iron dropoff * Steel dropoff * Plastic dropoff * Circuit dropoff * Processor dropoff * Battery dropoff * Rocket fuel dropoff * Rocket control dropoff * White science pickup (optional) Copper goes to LDS and solar panels. Iron goes to accumulators and radars. Steel goes to LDS and solar panels. Plastic goes to LDS. Circuit goes to solar panels and radars. Processor goes to satellite. Battery goes to accumulators. Rocket fuel goes to satellite and silo. Rocket control goes to silo. # Build plan ## Stations to build Listed in build order. * Iron smelting * Copper smelting * Circuit mfg * Refinery * Adv circuit mfg * Blue science * Research * Purple science * Alt-Yellow science * Black science * Alt-Rocket Silo ### Train count * 1-3 iron ore trains * 1-3 copper ore trains * 2 trains deliver to Circuit mfg * 3 trains deliver to Refinery * 2 trains deliver to Adv circuit mfg * 4 trains deliver to Blue science * 4 trains deliver to Research * 6 trains deliver to Purple science * 4 trains deliver to Alt-Yellow science * 4 trains deliver to Black science * 9 trains deliver to Alt-Rocket Silo 40 trains minimum (one iron ore, one copper ore) 44 trains maximum (three iron ore, three copper ore)
