EDIT: This has now essentially been superceded by Wooden Economy (https://mods.factorio.com/mod/WoodenEconomy), it's highly recommended that you use that instead. This is here in case anyone wants this single change in a simple manner without any of the other changes made by other mods.

This is a completely rewritten version of the original Wooden Rails mod, made for Factorio 2.0.

I recommend using this with a mod that allows you to grow wood, such as Just Another Greenhouse Mod
