context_page_description: The Prussian T 9 was a class of German steam locomotive which included several types of tank engine, all with six coupled wheels and two carrying wheels operated by the Prussian state railways.
context_section_description: Class T 9.3 of the Prussian state railways were tank locomotives that were used both in passenger and freight train services. A total of 2,060 were of this type were built for the Prussian state railways (including those engines from the East Prussian Southern Railway which was nationalised in 1903). The Royal Württemberg State Railways procured a further 10 examples as the Württemberg T 9. The Imperial Railways in Alsace-Lorraine had bought a total of  132 T 9.3s. Even various private railways took delivery of the T 9.3. In 1925 it was included by the Deutsche Reichsbahn as DRG Class 91.3-18 and 91.20 in its numbering plan.
  This was an evolutionary development of the Prussian T 9.2, in which the main difference was the use of a Krauss-Helmholtz bogie instead of an Adams axle. That meant that its top speed could be increased to 60 km/h, and later even to 65 km/h. The Reichsbahn took over 1,503 machines from Prussia as 91 303 - 1805, of which ten T9.3s originally came from the Imperial Railways in Alsace-Lorraine; 31 from the Saar Railway as 91 1806 - 1836 and 10 Württemberg T 9s as 91 2001 - 2010. In the Second World War more locomotives were added from Belgium as numbers 91 1837 - 1844.
  On 1 April 1949, the Deutsche Reichsbahn (GDR) took over yet more T 9.3s from private railway companies, with the numbers 91 6501, 6576, 6577, 6581 and 6582, some of which had been converted to superheating.
  Their retirement began after 1945 and was completed in the Deutsche Bundesbahn in 1964 and in the Deutsche Reichsbahn (GDR) in 1971.
  Six T 9.3s remained in Austria after the Second World War. Two were handed over to the SZD in 1948 (91 1700 and 1822), two were rather quickly retired (91 1421 in 1951 and 91 1314 in 1952). The remaining two engines, 91 1207 and 91 1347, formed ÖBB Class 691 retaining their serial numbers. Both were used in the St. Pölten region and retired in 1957.
  In Germany two have been preserved: number 91 896ᴵᴵ in Dresden and 91 936 in Berlin. The Minden Museum Railway is rebuilding a T 9.3.
  Two re-gauged examples are preserved in Russia. TT-1770 is preserved at TT-1770 at the Russian Railway Museum in Saint Peterburg. While another unrestored example is at a Railway Museum at Shushary, Saint Petersburg.
  One example is at the Steam Locomotive Park at Haapamaki, Finland
