in the first half of the 1940s, a large number of class 52 locomotives of the Deutsche Reichsbahn were equipped with condenser tenders. They were initially used in war zones east of Germany, later also in northern France and Belgium. Due to the lack of a steam plume, they were not so easily noticed by the crews of enemy aircraft and could also be used in areas where the infrastructure for the intake of feed water was no longer available due to destruction. After the war , some machines of the 52 series were konstationed in the Mainz-Bischofsheim depot. In 1950 there were 16 locomotives with the numbers 1853z, 1862, 1907, 1919, 1935, 1941, 1957, 1987z, 1997, 2001, 2005, 2013, 2014, 2015, 2017, 2020, 2021, 2022 and 2024z; other machines were stationed in Kirchweyhe, Duisburg-Wedau, Rosenheim, Munich-Ost and -HBf and Nördlingen, but were parked until mid-1954. In the area of what was later to become the GDR, 25 machines remained, which were used in the Cottbus area and converted into the normal version while retaining their company number. In Germany, the tender of 52 has been preserved in 1972 (source: Kondenslok.de), but no matching locomotive.
