“The Flying Train” depicts a ride on a suspended railway in Wuppertal, Germany in 1902. This colorized footage is almost as impressive as the feat of engineering it captures. Designed by Eugen Langen, it was built between 1897 and 1903 with the first track opening in 1901. The Schwebebahn is still in use today, moving some 25 million passengers annually as of 2008. It runs along a route of 8.3 mi.
