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.
The Hamburg Flyer, a train consisting of two cars – each having a driver's cab and passenger cabin – was ordered by the Deutsche Reichsbahn-Gesellschaft in 1932 from Waggon- and Maschinenbau AG Görlitz (WUMAG). The train was delivered in 1932 and put into service in 1933.
The train was streamlined after wind tunnel experiments, a sort of research which was pioneered by the developers of the high-speed interurban railcar Bullet a couple of years before. The Fliegender Hamburger design was very similar to the Bullet's. Its lightweight, articulated construction and Jakobs bogies were also known on the US interurban scene. However, the Fliegender Hamburger had diesel-electric propulsion. Each of the two coaches had a 12-cylinder Maybach diesel engine with a direct current generator directly coupled to it, which drove a Tatzlager-traction motor. The two engines developed a combined power of 604 kW.
The train had a pneumatic brake developed by Knorr and an electromagnetic rail brake. At 160 kilometres per hour (99 mph), it needed 800 metres (2,600 ft) to come to a halt.
