Schienenzeppelin By Franz Kruckenberg, Germany

In 1932 Kruckensberg began a new project with the rail car involving significant modifications. It was cut just behind the forward wheels and received a complete new front end with a two-axle bogie, resembling the later 137 155 railcar. The rear single axle remained as it was. The modifications were completed by November 1932. The aircraft engine was still used, however, the power transmission was hydraulic through two Fottinger- Fluid drives for both directions of travel, these were fitted on the forward bogie. A pointed fairing was installed in place of the propeller. These changes meant that the earlier 1-1 wheel arrangement was replaced by B-1 with the front axle replaced by a powered bogie.This version of the vehicle reached 180 km/h (110 mph) at the beginning of 1933.
Due to many problems with the Schienenzeppelin prototype, the Deutsche Reichsbahn-Gesellschaft decided to go their own way in developing a high speed railcar. In 1933 the DRG built a high-speed railcar of their own design and called it Fliegender Hamburger (Flying Hamburger). DRG's new design was suitable for regular service and served also as the basis for later railcar developments. However, many of the Kruckenberg ideas, based on the experiments with Schienenzeppelin and high speed rail travel, found their way later to DRG's railcar designs.
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.
