Streamlined locomotive

A streamliner is a vehicle incorporating in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor "bullet trains". Less commonly, the term is applied to fully faired recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels.

The first high-speed streamliner in Germany was the "Schienenzeppelin", an experimental propeller driven single car, built 1930. On 21 June 1931, it set a speed record of 230.2 km/h (143.0 mph) on a run between Berlin and Hamburg. In 1932 the propeller was removed and a hydraulic system installed. The Schienenzeppelin made 180 km/h (112 mph) in 1933.

The Schienenzeppelin led to the construction of the diesel-electric DRG Class SVT 877 "Flying Hamburger". This two-car train set had 98 seats and a top speed of 160 km/h (99 mph). During regular service starting on 15 May 1933, this train ran the 286 kilometres (178 mi) between Hamburg and Berlin in 138 minutes with an average speed of 124.4 km/h (77.3 mph). The SVT 877 was the prototype for the DRG Class SVT 137, first built in 1935 for use in the FDt express train service. During test drives, the SVT 137 "Bauart Leipzig" set a world speed record of 205 km/h (127 mph) in 1936. The fastest regular service with SVT 137 was between Hannover and Hamm with an average speed of 132.2 km/h (82.1 mph). This service lasted until 22 August 1939.
