Hi guyz... How do I download and install addons from the steam workshop? I am playing Train Simulator 2021 and when i enter the workshop it comes up with Train Simulator 2020. Will the addons still work despite this? Thank you.
Yes, just subscribe and it will be downloaded to your Library. Make sure you have all the requirements, route and rolling stock, needed to make it work.
I'm not sure I understand what you're really asking. Anything from the Steam Workshop is free. Anything that is DLC from the TS2021 Steam Store Page, must be purchased. There are no in-game purchases or special currency. All DLC purchases go through Steam.
