DRG Class 84

The German DRG Class 84s were standard (see Einheitsdampflokomotive) goods train tank locomotives with the Deutsche Reichsbahn. A total of twelve engines were placed into service by the Reichsbahn between 1935 and 1937. The machines were given operating numbers 84 001–012. They were worked on the Müglitz Valley Railway (Müglitztalbahn) between Heidenau and Altenberg in the Ore Mountains (Erzgebirge), for which they were specially designed to negotiate tight curves. They were manufactured by the firms of Berliner Maschinenbau and Orenstein & Koppel. One feature was that they were Berliner-built locomotives were fitted with Schwartzkopff-Eckhardt II bogies, while the O&K-built had Luttermöller axles. In the Second World War many of the engines were damaged and had to be sidelined as a result. The vehicles were taken over by the DR in East Germany after the war. The engines were mainly used between Schwarzenberg and Johanngeorgenstadt. The entire class was withdrawn between 1966 and 1968 apart from one, and all were scrapped.
