“The Flying Train” represents a ride on a suspended railway in Wuppertal, Germany in 1902. The video is almost as exciting as the feat of engineering it represents.
According to the MoMA, the footage was shot on Biograph’s exclusive 68mm stock which gives remarkable visual clarity and quality, especially compared to the more standard 35mm or 16mm stocks of the time.
The Wuppertaler Schwebebahn (Wuppertal Suspension Railway) is a railway in Wuppertal, Germany.
Designed by Eugen Langen, it was constructed between 1897 and 1903 with the first track open in 1901. The Schwebebahn is still in use today, transferring some 25 million passengers annually as of 2008. It runs along a route of 13.3 kilometers (8.3 mi). [source]
