The Flensburg type was a four-axle benzene railcar designed for the Flensburg and Rendsburg county railways. Each received two in 1925, which had four axles and a four-cylinder benzene engine delivering 75 hp. This engine powered both axles of one bogie via a pneumatically switched four-speed gearbox. Often they also hauled trailers.
All were later rebuilt to diesel engines. The two from the Flensburg county railway got a 145 hp eight-cylinder diesel in 1949, while the two from the Rendsburg county railway got a DWK 6V18V diesel with originally 80 and later 105 hp in 1939 and 1949. They were withdrawn by the end of the sixties and today the T1 of the Rendsburg county railway is being preserved as T43 by the DEV Bruchhausen-Vilsen.
