Also added coaches ("Black Gold", "Firefly", "Chouteau Club", and "Bluebonnet") that Frisco 1522 pulled on her excursions in the late 1990s and early 2000s. (Released 4500 and 4504 steam tenders as an unrelated bonus)

5/3/25: The Great Re-texture: Re-textured most of the assets of the pack so that they have baked, defined textures rather than a flat look.

Plan for upcoming versions: Version 4 will feature steam from the Espee (Southern Pacific), including the 2472 P-8 and the 4405 Gs-1, possibly a new livery for the Frisco Chouteau Club to go with SP. Versions after this will include the Southern 4501, and may feature a triplex, either the Erie triplex or a kitbash triplex, and also could feature the UP 6936 EMD DDA40X "Centennial," otherwise known as the largest diesel locomotive ever built.

Note that no one is allowed to redistribute, edit, or use my models without my permission. There is no harm in asking me though. I hope not to find elements of it somewhere else than here that I have not been told about.

This resource pack works for any version that you are playing IR in, regardless that it says 1.12.2. Have the Immersive Railroading, Universal Mod Core, and Track API mods installed and enabled for this resource pack to work.
