Even train unloading
I started playing Factorio two weeks ago, and it's... mentally stimulating and addictive!
I passed the last two days figuring out a good way to evenly unload a train, and this is my end result that I am now building in my world:
String (2-8-2 Train version, but it's tileable to any size)
My initial problem was that I was directing each wagon to a single belt each: the problem with this approach is that, if one belt consumes more items than the others, the corresponding wagon will empty faster than the others, creating more work on timing your train stop correctly, and preventing unused items from other wagon reaching the empty belt.
So, I decided to "merge" each wagon, from each side, converging everything to two circular belts, and with one exit each wagon.
This way, every output belt is fed by every wagon, and they should empty evenly.
Did I overengineered, or is this the right approach to what I was looking for?
