Schienenzeppelin By Franz Kruckenberg, Germany

At the beginning of 1934 the train was rebuilt for the last time, and a Maybach GO 5 engine was installed. In July 1934 it was sold to Deutsche Reichsbahn (German Imperial Railway) for 10,000 Reichsmarks. Five years later, in 1939 the rail zeppelin was finally dismantled because its material was needed by the German army.
Criticism
The failure of 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 highspeed railcars.
