The Prussian S 6 (later DRG Class 13.10–12) was a class of German steam locomotive with a 4-4-0 wheel arrangement operated by the Prussian state railways for express train services.
Development
After the Prussian steam locomotive classes
In 1905/1906 Garbe pushed through the construction of the S 6. Between 1906 and 1913 a total of 584 units were manufactured by
Design features
The design initially caused major difficulties, because it had to keep to the maximum permitted axle load for the railway network of 16 t (15.7 long tons; 17.6 short tons).
This limitation led to the weight savings in many areas. At first, the
The
Not until the lines were upgraded in 1910 to take a 17-tonne (16.7-long-ton; 18.7-short-ton) axle load, could the necessary reinforcing measures be taken. The S 6 then became the heaviest 4-4-0 locomotive on continental Europe, even outweighing the subsequently built four-cylinder, saturated steam locomotives of Class S 7.
The driver's cab was initially built with a tapered front and conical smokebox doors in order to reduce wind resistance. An unfortunate side effect of the streamlined driver's cab, however, was that the engine crew were dazzled at night by reflexions from the diagonally oriented front window panes. From 1908/1909 the cab was built with a flat front.
The locomotives were equipped with Prussian Class pr 2’2’ T 21.5 tenders.
Performance
The S 6 achieved its highest indicated power of 1,160 PS (870 kW or 1,170 hp) at a speed of 100 km/h (62 mph). On the level it could haul a train of 500 tonnes (490 long tons; 550 short tons) (the equivalent of 13 eight-wheeled

After the
Preserved locomotives
From 1912 the S 6 was ousted from heavy express train services by the S 10.
In the 1923 DRG renumbering plan for steam locomotives, 442 S 6 engines were listed for renumbering into the 13 1001 to 13 1442 series. In the third and final renumbering plan only 286 engines were listed: numbers 13 1001 to 13 1286.[1] The last engines in Germany were retired between 1926 and 1931.
After World War I, 81 locomotives were handed over to Poland (class Pd5), 42 to Belgium (type 66), two to Italy (class 553) and one to Lithuania as reparations.[2] The engines in those countries survived considerably longer in service; in Belgium they were not retired until 1956.
During the
One S 6 has been preserved in Warsaw (Poland).
