Schienenzeppelin

Propulsion was by means of a pusher propeller located at the rear: it accelerated the railcar to 230.2 km/h (143 mph) setting the land speed record for a petrol powered rail vehicle.

Anticipating the design of the Schienenzeppelin, the earlier Aerowagon, an experimental Russian high-speed railcar, was also equipped with an aircraft engine and a propeller.

The body of the Schienenzeppelin was streamlined, having some resemblance to the era's popular Zeppelin airships, and it was built of aluminum in aircraft style to reduce weight.

On 21 June 1931, it set a new world railway speed record of 230.2 km/h (143.0 mph) on the Berlin–Hamburg line between Karstädt and Dergenthin, which was not surpassed by any other rail vehicle until 1954.

The aircraft engine was still used; however, the power transmission was hydraulic through two Föttinger fluid drives for both directions of travel, fitted on the forward bogie.

[3] The failure of the Schienenzeppelin has been attributed to everything from the dangers of using an open propeller in crowded railway stations to fierce competition between Kruckenberg's company and the Deutsche Reichsbahn's separate efforts to build high-speed railcars.

Safety concerns have been associated with running high-speed railcars on old track network, with the inadvisability of reversing the vehicle, and with operating a propeller close to passengers.
