The
steam locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomot ...

locomotives in service with the
Deutsche Reichsbahn in
East Germany after the
Second World War.
These engines were rebuilt from
DRG Class 39.0-2 locomotives and appeared between 1958 and 1962 as part of the
reconstruction programme. The latter had a significant problem: the
boiler did not generate enough steam and the steam pipes were too winding, which considerably reduced the maximum power of the engine. A total of 85 examples were equipped with a new
combustion-chambered boiler with an ''IfS'' mixer-
preheater
An air preheater is any device designed to heat air before another process (for example, combustion in a boiler With the primary objective of increasing the thermal efficiency of the process. They may be used alone or to replace a recuperativ ...
. The
locomotive frame had to be extended to accommodate the new engine. The wider outer firebox meant that the driver's cab needed a modified rear wall. The locomotives were given operating numbers 22 001–085 and were mainly homed in the Reichsbahn divisions of
Dresden and
Erfurt
Erfurt () is the capital and largest city in the Central German state of Thuringia. It is located in the wide valley of the Gera river (progression: ), in the southern part of the Thuringian Basin, north of the Thuringian Forest. It sits in ...

The DR employed the locomotives on heavy express train duties in the schedules for the
DRG Class 01, which led to overloading of the original components (frame cracks, piston damage). As a result, early retirement followed.
In 1968, 50 of the 85 ''Reko'' boilers from the Class 22 were used for the reconstruction of the
DRG Class 03.
In 1970 the engines were allocated to Class 39 under the DR's new computerised numbering scheme. However, in 1970 only a few machines were still working, at
Halberstadt and
Saalfeld. In 1971 the last one was withdrawn. Up to the early 1990s, nine engines were used as steam generators.
The vehicles were equipped with 2'2' T 32 or 2'2' T 34
tenders.
