This was fascinating! Even more, watch the side-by-side video 1902- 2015 (I think). Amazing, the changes to the buildings and landscape. Nice find!The Wuppertaler Schwebebahn Railway is a suspension railway in Wuppertal, Germany. It's the oldest electric elevated railway with hanging cars in the world, and began operation in 1901.
This video from 1902 has an uncanny surreal feel to it, blending together the past and the future. It was recently enhanced and upgraded by the Museum of Modern Art in New York. I found it to be mesmerizing!
