I have found what looks like great mods on here that I would like to add to my game; can anyone explain how to do this in the Steam Version. I have located the file location on my desktop PC but I am worried that if I add a RES file (for example) it will overwrite anything that is required, or does it just replace with new? If there is some new models of trains do I just add their actual files, and if so to where?
I am really a nivec to anything to do with modding. Thanks in advance
