BR 17.0-1

From the technical service of the directors of Kassel, Elberfeld, Erfurt and Frankfurt of the Preußisch-Hessischen Staatsbahn became the need of a powerful express train locomotive. The Prussian railways decided to built a steam engine with three coupled axles. Schwartzkopff delivered in 1910 two prototype locomotives which got the indication S8 (from 1912 S10). But the locomotives did not satisfy the expectations, as a result the construction had to changed. The frame was modified, so that the driving transmission was much more accesible. After two additional changes (the boiler pressure was raised from 12 bar to 14 bar), the locomotive was satisfying. The locomotives got from 1911 the indication S10. The S10 was capable of pulling a train of 390 ton on a flatland with a speed of 100 km/h, and on a hillside of 10‰ pulling a train of 360 ton with a speed of 50 km/h. Between 1911 and 1914 there are 200 steam engines of type S10 built, they had mainly their service in express trains on mainlines.
