At the model railway exhibition, called Intermodellbau Dortmund, the company Rautenhaus Digital was presenting this beautiful demonstration layout of a model railway in N gauge with full digital command control. A small but a fine model railway layout. Since 1993 Rautenhaus deals with model railroad technology, especially in the field of developing and manufacturing components for digital model train control systems.
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.
