Train simulators always had American, German and UK routes all the time, I love those routes but I think they should focus more on other European countries too. I would love to see some Belgian routes, it's a fairly small network but quite beautiful and challenging to drive since it's very busy for being so small. Besides that and the interesting locos it has also a few stunning stations ex. Antwerp Central Station, Leuven Station, Liège-Guillemins
Guillemins station is not a station. That's two hundred thousand tons of pure art, or how ever much this thing weighs
