It is working for me with this mod, make sure you dont have any other versions of easy dev downloaded, and get a fresh download of my edit and see if it works? If not, try starting a game with just this mod and the locomotives enabled. It could be a mod conflict?
I had only this mod, the locomotive mod, the rolling stock and the placeable track enabled only the rest i had are disabled and i downloaded this and putted it into the mod folder and it told me to update it for some reason maybe that might be the issue?
