The DRG Class SVT 877 Hamburg Flyer – sometimes also Flying Hamburger or in German Fliegender Hamburger – was Germany's first fast diesel train, and is credited with establishing the fastest regular railway connection in the world in its time. Correctly named the Baureihe SVT 877 (later DB Baureihe VT 04 000 a/b), the diesel-electric powered train was used to carry passengers on the Berlin–Hamburg line (roughly 286 km or 178 mi). It entered service in 1933.
