This model railway layout is designed as a modular system in N scale. It was built by a railway club from France. The members of that railway club have focused entirely on the N scale. On this modular model train system, there are the TGV and other French locomotives and trains.
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.
