Wuppertal Floating Train / Wuppertaler Schwebebahn Key Ring

The amazing Floating Train or Sky Train from Wuppertal, Germany. Built in the beginning of the 20. century, this technology helped the city Wuppertal to implement public transportation in a densely populated area, by building the train right over the river Wupper. This photo shows a beautiful red train coming into one of the train stations high above our heads. Beneath it, you can see the river Wupper.
