“The Schienenzeppelin or rail zeppelin was an experimental railcar which resembles a zeppelin airship in appearance, designed and developed in 1929. Propulsion was by means of a propeller located at the rear, accelerating the railcar to 143.0 mph, setting the land speed record for a petrol powered rail vehicle. Only a single example was ever built, which due to safety concerns remained out of service and was finally dismantled in 1939.”
