INSTALLS VIA UMM
PLEASE SEE REQUIREMENTS FOR REQUIRED MODS!
What do all the names mean?
The class system is:

For example:
Tenders also use a unique class system:
coal capacity (in tons) - body style - water capacity (in thousands of gallons)
For example:
Possible tender body styles:
Clear vision
Why does my locomotive randomly seem to run into an invisible wall?
Please update your mod to the latest version!
Where do I get the tender swaps?
They can be found under "Optional Files" on the download page!
Why are only some of the locomotives showing up in my buy menu?
You may have the wrong UMM version, or the wrong version of one of the required mods. Please double check them!
Why does the 282-S-35A have two bells as an option?
The Mississippi Central had two bells on every locomotive as a failsafe, and I thought it would be a neat thing to represent.
This may or may not be the single most colossal undertaking i have ever committed, being in the making for over 3 months now.
Genuinely the most involved project I've ever taken on. I learned so much and gained quite a few new skills!
With that said,
i am never doing this again.
