Im trying to add custom trains such as this pack https://modrinth.com/resourcepack/mtrsydney_metro_and_trains?version=1.20.4 and https://modrinth.com/resourcepack/mtrnsw-trainlink-emu-trains
But for some reason i can only use them when i export through the resource pack creator and only one train pack at a time and i have no clue on adding them permanently.
Any help will be great
