#Factorio bus upgrade#

Of course most of the time the quantities needed by the branches vary over time and so does your input (you might upgrade to red/blue belts, add more to the bus, bring extra belts from one side to 'resuply' the bus.). If another branch needs a full belt to work, you now have 2.5 belts worth of throughput (assuming you had 4 and not 1 belt being split into 4 in the first place of course).ДЄt that point it's completely fine to only have 3 belts for iron plates on your bus instead of sticking with 4 and having a lot of holes in it. The issue of proper balancers is that it leaves belts more and more empty but with the same amout of belts, which isn't really what the bus is about.ДЄ main bus is all about bringing resources from a central line of belts towards the various places that need them, so lowering the amount of belts once the thoughput is no longer enough to support all of them isn't a bad call.ДЇor example, let's say your first branch requires half a belt of iron plates from your 4 lines, you now effectively only have 3.5 belts on your bus. If you want to use the 'inside' belts as a way to refill the 'outside' belts you can even use the priority output function of the splitters. It doesn't have to be a full balancer, it can just be a chain of inserter either from the 'inside' belts or from the opposite side (depending on if you frequently take from both sides or not) to the side you just took from. If you mainly take from the 'outer' belts for each item you want to have some form of balancing.
