Amazing German Rail Zeppelin (Schienenzeppelin) (7 pics)
Rail Zeppelin (Schienenzeppelin) was built at the beginning of 1930 by Franz Kruckenberg. It had BMW VI 12 cylinder petrol aircraft engine of 600 horsepower (450 kW) driving a four-bladed (later two-bladed), fixed pitch wooden (ash tree) propeller. On June 21, 1931 Schienenzeppelin set a railway speed record of 230 km/h (140 mph) on the Berlin–Hamburg line that would stand for 20 years. The record was not surpassed by any other train until 1954. The Rail Zeppelin was never put into production.
