This is something that it's hard to calculate and I suppose should be set from experience so I'd like to ask : What is the highest comfortable ratio of production speed (filling up station warehouse) to train loading speed at provider stations ? I'm using 2 wagon trains for high yield and 1 wagon tr...

But it's really nothing to worry about. LTN won't send a train to a station that can't fill it, That's the important part. So what if, worst case, they all go to one station if that station can supply all the needed iron?

That won't be a problem. I'm going forward with my building then.

The most effective balancing that happens I believe is that LTN remembers what trains have been send to each station and corrects their provider amount accordingly That seems to be enough for me. I was planning to divide my iron and copper production into blocks each having their own input & ou...

I wonder how LTN selects best provider if there are multiple providers of the same item ?

Is there some kind of balancing mechanism ? Or do I have to take care of it myself ?

So far I relied on single provider per item, but I'm expanding and I will need to change that.
