Yuoki Trains are beautiful but they are a pain in the ass to craft, and most of the trains are actually worse than the vanilla locomotive. This mod aims to simplify the recipes so they are more practical to craft.
Currently all the trains and wagons are unlocked by default, but I'm planning to implement a tech tree and change the ingredients to keep them in proper tiers.
