In this colorized photo by Jecini, Check out the gorgeous Schienenzeppelin in Berlin in June of 1931. A train is going to Hamburg passes the newly arrived ‘rail zeppelin’ at Spandau’s main station.
The Schienenzeppelin or rail zeppelin was an innovative railcar that looked like a Zeppelin airship in appearance. It was designed and produced by the German aircraft engineer Franz Kruckenberg in 1929.
Propulsion was achieved by the pusher propeller located at the rear: it quickened the railcar to 230.2 km/h (143 mph) setting the land speed record for a petrol powered rail car. Only a single train was ever built, which due to safety concerns it kept out of service and was finally dismantled in 1939. [source]
