Factorio Blueprints

Unloading BPs contain ghost scanner. Blueprints can work without it, it is used only for real-time ordering of items for buildings. Just use constant combinator. Get rid of timers, now train wait for sygnals; Simplified scheme; Removed some deciders; Now you need only one loading\cleaning station; Removed BP without requester chests; Removed construction BPs;

Only one combinator used to set amount of materials which will be added to cars. With global network, you can set amount on unload station and it will be delivered to requester chests at loading point. Limit of station will be set to 0 after every asked item will be delivered. If combinators are enabled then the unloading station will request any missing items from the network. Thus, you can make an endless delivery of any missing items. You just need network for it. Additional segments of loading\unloading stations should be placed overlapping existing because of logistic wires. More segments you add less precise it will be, but Im too lazy to set millions of chests\cars manually anyway, soooo Im ok with it.
