📋 About This Mod
2-8-8-4 Yellowstone built for the Duluth, Missabe, and Iron Range railroad
The DM&IR M-3 Yellowstone is a large 2-8-8-4 articulated steam locomotive. Built by Baldwin locomotive works in 1941, it was designed to pull 8000 ton trains from the iron mines to the ore docks on lake Superior in Duluth. Boasting 140,093 pounds of tractive effort (~5k more than the Union Pacific Big Boy), these beasts can move an insane amount of traffic on your line.

EDIT: PLEASE READ
If you're having trouble installing the Yellowstone, try uninstalling all associated mods through UMM, and then reinstalling everything. I don't know the exact reason why this fixes the issue of the locomotive not appearing in the spawn menu (even if the mod loads correctly), but it has consistently fixed this issue.
