Saarbrucken 2-6-0 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class T9.2 / 91.0 (Locobase 5098)

Data from [], last accessed 14 May 2011.

This was a set of a class of tank engines very similar in size to the much more numerous

Prussian T9.1 engines. They first saw service in the Saar basin, later in the DRG.

A survivor is described on [] ... (August 2002). The DRG sold 91.134 to the Braunschweiger State, but regained control when that railroad was nationalized in 1938. A few years after the end of World War II, the German Armed Forces based the engine in Schwerin, where it operated until 1963. Its retirement in 1965 and it lay mostly dormant until its restoration in 1990.
