Bergische Museumsbahnen

The Bergische Museumsbahn is a heritage tram museum situated in the German city of Wuppertal. It operates its own tram line south of Wuppertal on original rails with original cars. Therefore it's one of the smallest running tram systems in the world. Wuppertal operates still the "Schwebebahn", a unique overhead railway.
