Every two years there is a model railway exhibition in Germany for US railroads. This layout is called "Port of Fairhaven" and was built in HO scale. On the model train layout there are the city of Fairhaven, its harbor area, warehouses, roads and, of course, with railroads.
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.
