The steam locomotives of the class S 4 of the Prussian State Railways (later class 13.5 of the Deutsche Reichsbahn ) were superheated steam express locomotives .
Prototypes
In 1898 a Prussian S 3 was equipped with a flame tube superheater for testing purposes, making it the world's first superheated steam express train locomotive. It was initially given the designation Hannover 74 and was ultimately run as the S 4 Cassel 401 . Two further test locomotives were built in 1899 and 1900 as the Hannover 86 and Berlin 74, also based on the S 3, but with a smoke chamber superheater. They were later redrawn as S 4 Hannover 401 and Osten 401 .
Series machines
After initial difficulties could be resolved, the S 4 was built in series from 1902, it was an independent development compared to the first prototypes. Smoke chamber superheaters were installed until 1906 and smoke tube superheaters from 1906. A total of 104 copies were made; then from 1909 the procurement was given up in favor of the Prussian S 6 .
The machines managed a tensile load of 420 t at 80 km / h on the level and a tensile load of 210 t at 50 km / h on a gradient of 10 per thousand. The S 4 was around a third more powerful than the S 3. In high-speed tests for comparison with the Prussian S 9 Altona 561 on the Marienfelde - Zossen section of the Royal Prussian Military Railway, an S 4 reached a speed of 1904 with the test train consisting of three cars 136 km / h.
Before the First World War, most of the locomotives in the series were already decommissioned. In 1923, the Deutsche Reichsbahn took over 44 S 4s in their preliminary re-drawing plan as 13 501–544, which were still used in passenger or freight train service. In 1925 there were only four copies left. In 1925 these were given road numbers 13 501–504 and were retired by 1927.
During the Second World War five S 4s from Poland ( redrawn Pd2 ) came into the Reichsbahn's inventory as 13 401–405 . Two of them were only returned to Poland by the DR in 1955 . Few of the machines remaining on the territory of the FRG were still z-placed in the DB inventory in 1950.
The locomotives were equipped with pr 2'2 'T 16, pr 3 T 13 and pr 3 T 15 tenders .
