BR 17.11-12

In 1913 Georg Heise is working for Henschel in order of the "Eisenbahn Zentralamtes" to change to construction of the S10.1. The weight had to be lowered, in order to install a waterpreheater. At the S10.1 (version 1914), the inner and outer cylinders were lying flat, that meant that the outer cylinder was not fixed at the bogie end, but between the bogie axles.

Of the version of 1914 were 102 locomotives built. These locomotives were brought into service in all heavy express train services on the mainlines. The locomotives were capable of pulling a train of 450 ton with a speed of 100 km/h, at testruns a locomotive reached a speed of 152 km/h.

In service at the DRG

The DRG had changed the service district of the S10.1 to Northern Germany when the BR 01 was delivered. After the introduction of the BR 03 the S10.1 was changed to services for less high graded express trains. In the thirties the boiler of the steam locomotives were replaced, and the locomotives were retained because they were not enough standard design locomotives. The last locomotives S10.1 were set aside in 1964. The 17 1055 (ex OSTEN 1135) was preserved and is now standing in the traffic museum in Dresden.
