What a nice railway. When you first start looking, it is always a puzzle, what is the track width? I think in your case it is H0. It is not mentioned anywhere and not in many RU-vid videos from other hobbyists. That's too bad. Have fun with the railroad hobby. I only have track width N 1:160. Best wishes Robert.
Nice! I definitely think one thing that O gauge trains have is in the accessory detail. Like that crane is super impressive. If i could ever have space to do so stuff like that is super cool.
