Watch this footage and try to guess when it was recorded.

Amazingly, it’s from 1902. The cities of Elberfeld and Barmen in western Germany had begun to discuss an elevated railway as early as 1887; they enlisted engineer Eugen Langen, and the line opened in 1901.

The Wuppertal Schwebebahn is still in use today — the world’s oldest electric suspension railway carries 85,000 passengers a day on an eight-mile route through the city of Wuppertal, much of the journey unfolding 12 meters above the River Wupper. Local poet Else Lasker-Schüler compared it to a flight on the back of a steely dragon.
