Installed mods per instructions some worked some did not on day 1. On day two none of the mods worked, as if Train Sim World ignored the mods all together. Mods that worked at first were GP38-2 CN, and AC4400 BNSF. Not sure why they stopped working but the next day Train Sim World went back to the defaults.
I also put my downloaded files in the ~mods folder and they did not work, I made a copy of the files and moved them to the dlc folder and they are now working. Hope this helps others!
