The Schienenzeppelin (German: [ˈʃiːnənˌtsɛpəliːn]) or rail zeppelin was an experimental railcarwhich 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 pusher propellerlocated 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. Only a single example was ever built, which due to safety concerns remained out of service and was finally dismantled in 1939.
