The German Schienenzeppelin (means Rail Zeppelin), the prop-driven V12 locomotive, developed by Franz Kruckenberg in 1929
“The Schienenzeppelin or rail zeppelin was an experimental railcar which resembled a zeppelin airship in appearance. It was designed and developed by the German aircraft engineer Franz Kruckenberg in 1929. Propulsion was by means of a propeller located at the rear, it accelerated the railcar to 230.2 km/h (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.”
