Bulk train loader/unloader with buffer.
Mods introducing new content into the game.
Augmented or new ways of transporting materials - belts, inserters, pipes!
Does it scale with inserter capacity bonus?
ik it used to increase in loading speed when u started upgrading inserter stack sizes not sure if it still does
I found fix. In prototypes/entity/railloader.lua and prototypes/entity/railunloader.lua you have to change stack = true to bulk = true.
