This modification greatly simplifies the creation of trains for the Create mode. Instead of performing rather complex procedures for crafting some components, simply wash iron ingots to prepare wagon casings. To create rails, you only need to combine iron and stone slabs in a regular crafting table recipe!
The modification is fully compatible with the add-ons Create Steam and Rails, making this interaction completely safe and super convenient.
P.S. Don't forget - the simpler, the better!
