This model train layout in HO scale was built by German modellers from Cologne. There are three different landscapes covering the whole model railway layout. And, there are a lot of North American locomotives and freight trains, including Amtrak or CSX, etc. The model railroad layout was carefully designed with a beautiful snow cover.
Actually, there are more than 250 videos about model railroading and railway modelling, for example, on Dailymotion and YouTube. Please, visit also Pilentum's Facebook site.
