Oldenburg S 10

The express train locomotives of Oldenburg Class S 10 were built for the Grand Duchy of Oldenburg State Railways
for duties on the Bremen

–Wilhelmshaven
line, which was the most important express route in Oldenburg. They were amongst the few locomotives of this railway company that were not based on those of the Prussian state railways
, because the light railway track dictated that they had to have an average axle load of no more than 15 t which was lower than that on comparable Prussian vehicles.
The three vehicles of this class were built by Hanomag
from 1917 and had a 2-6-2
(Prairie) wheel arrangement
which was rare for Germany. They had Lentz valve gear which was typical of Oldenburg. The engines had an uneven distribution of load, however, as well as poor riding qualities and were often bedevilled with boiler
problems. In addition, an incorrect matching of the radiative and tube heating areas led to leaks in sides of the tubes.
The three S 10 engines were grouped by the Deutsche Reichsbahn
into Class 16 with operating numbers 16 001–16 003. They were the only express train locomotives with a 2-6-2 wheel arrangement and therefore had their own class. After the lines were upgraded to 17 tonnes axle load, the temperamental S 10s were retired by 1926 and replaced by Prussian P 8
s that had been employed in Oldenburg since 1921.
The locomotives were coupled with Oldenburg class 2'2' T 20 tenders.
