Industry and facilities setup guide?

Are there any in depth guide for setting up industries, interchanges, repair and fueling facilities in the map editor? I’m kind of fumbling my way through it but I have coal mines that I’d like to set up to take mine parts in boxcars as a condition of loading but the industry unloader gives me an error saying no car filter applied, I put boxcar, XM, even the exact name of the car type to order and it keeps throwing the error at me. Any help appreciated!

Best way to learn is to look at how the base game does it. Copy the Railroader/Railroader_Data/StreamingAssets/AssetPacksCore/nc-bryson-terrain/ folder into your ModDev folder, and then you can open the base game’s map in the editor to reference it.
