If anyone is interested, I found a solution that is pretty simple. Just have one filter inserter connected to all the other inserters with circuit network and configure it to read the contents that the other inserters are holding. Then set the filters of the filter inserter to that signal. Force the...

Hmm, I'd just use two trains with two train-stations, because reducing train traffic is a huge priority in the endgame. Train stations take up space, but space is infinite. Any solution that incurs unnecessary traffic seems suboptimal to me... I prefer to have one train that leaves when either reso...

The answer to question #1 is simple: standardize the number of items you load onto a wagon at any given station. As long as all the various items served by a station have the same stack-sizes, my circuit-methodology works. Ah thats what I am trying to avoid. I want a general solution that works for...

I don't really know why you'd use stack filters to load a wagon, because cargo-wagons have filters if you just middle-click on the contents (just like your toolbelt). Thats what a stack filter is. https://wiki.factorio.com/Cargo_wagon Im not sure if I am following the pulse counting method. How do ...

Does this work if the cargo wagon has stack filters to allow for more than 1 resource?

Also in my situation my trains are 2 cargo wagons long. One cargo wagon is loaded while the other is unloaded. Will this still work?

For unloading my approach was to use filter inserters combined with circuit network similar to what SyncViews said. Loading is the part I am running into issues with. Say I have two trains, one has stack filters to allow only iron to be loaded, and one has stack filters to allow only copper to be lo...

Oh you're right you can have one box with multiple items in it. My statement would be more accurate if I said multiple chests cant share any resource types unless there is only one resource. I should probably explain what I want to do to show why i think this is a good idea. I am trying to make a si...

TLDR: In the situation where a train cargo wagon has stack filters to allow a set amount of each resource to be loaded on to it, inserters can become stuck if more than one is loading the cargo wagon. I have seen other posts describing this problem as a bug, but it seems that this is intended behavi...
