This book contains a smelting part and some tracks for the binary tree.
How to Use
Place as many smelting parts you need, connect it to an binary tree like in the screenshoot. The tree will help spreading the trains with as little blocking as possible. May place a stacker at the tree start. If you have to extend the setup with more smelter extend the tree acordingly, you may have to move the stacker or the tracks leading to the start in this case. The key is to have equal long tracks from tree entrance to each station to get the best routing out of the system.
It is working with 2-4-2 or 2-4-0 Trains.
In the screenshoot it is fully running with 32 stations (8 times the smelter blueprint part) that provides a staddy flow of 153k/m
