I had a danish friend buy it for me in Germany. You should try either Walthers or Euromodeltrains.com, they have both advertised them at some point. It is a model made by the German company Viessmann.
the only thing i can think of to add to your video /layout is maybe you can add a fan so the trees look like a breeze is flowing....idk, just a thought
WOW! All i can say is WOW! Your layout is fantastic and the attention to detail is simply OUTSTANDING! I just ran across your channel and sub'd right away after watching this video. Simply INCREADIBLE!
Those are Riverpoint Station models. I just learned that they were bought out by Atlas in december 2022, so no telling when they will come back. These models will probably be vintage by the time Atlas gets them back on the market.
