At the worlds largest model railway exhibition, called Miniature Wonderland, the small self-driving cars were used for the first time on model train layouts. They call it microcar, minicar, car system or Faller Car System, DC Car or simply model car. The city edge layout model railroad in HO scale includes more than 100 mini cars. Pilentum tried to film the streets and houses always from a frog’s perspective.
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.
