The first steam locomotives of the Baden Class VI c were delivered in 1914 by the Maschinenbau-Gesellschaft Karlsruhe for service in southwestern Germany with the Grand Duchy of Baden State Railway (Großherzoglich Badische Staatsbahn).

Their design benefited from experience with the Baden VI b steam engines, but they were a fundamentally different class with a superheater, new running gear with larger wheels and a longer, fixed wheelbase. The boiler was pitched higher, and the double steam dome was done away with along with its connecting pipe.

The Grand Duchy of Baden State Railway procured a total of 135 of these engines between 1914 and 1921 in nine batches. After the end of the First World War, 15 locomotives had to be given away to France and 13 to Belgium as part of the reparations required under the terms of the Versailles Treaty. The remaining 107 went to the Deutsche Reichsbahn. The lighter units of the first seven series were grouped into DRG Class 75.4, the heavier vehicles with a reinforced locomotive frame of the last two series were designated as DRG Class 75.10-11.

After the Second World War 66 Class VI c engines went into the Deutsche Bundesbahn, where they were stationed at various locomotive depots including Freiburg, Offenburg, Radolfzell, Singen, Waldshut, Karlsruhe and Villingen. In 1967 the last one serving with the Bundesbahn, number 75 1118, was retired. The Deutsche Reichsbahn in East Germany still had some of these engines working at that time.
