All aboard for Austria! Take charge of cross-border passenger & freight traffic with RSSLO’s Salzburg - Rosenheim route for Train Simulator. Read the article here.
Why does RSSLO always showcase their routes with bland generic locations that could be anywhere? I like their routes, but their marketing undersells them.
Train Team Berlin produce "Plus Packs" for the old default Kuju German stock which give you new features, sounds, repaints etc. These would have the advantage of improving the default stock everywhere, not just this route. I've yet to try them, but YouTube videos look encouraging.
