The T 9 Elberfeld type of the Prussian State Railways were freight train tank locomotives with the C1 ' wheel arrangement. The vehicles were planned for the route between Elberfeld and Cronenberg ( Burgholzbahn ). For this purpose the company Krauss & Comp. four specimens that were very similar to the Bavarian DVIII , as the Prussian T 3 was thought to be too weak. After the locomotives had proven themselves, Henschel made another 33 copies.

In the redesignation plan of 1923 it was planned to classify the locomotives as class 90 3 with the road numbers 351-363. In addition there were machines classified as T 9 1 with the numbers 90 154, 155, 167, 180-183. In the redesignation plan from 1925, only one locomotive was included as the 90 116. This was retired in 1931. Seven of these locomotives were given to private railways, where they were in service until the 1950s.

The T 9 type Langenschwalbach of the Prussian State Railways were passenger train tender locomotives with the axle formula C1 '. The vehicles were planned for the Aartalbahn between Wiesbaden and Langenschwalbach (today Bad Schwalbach), as this route with gradients of up to 33 ‰ had proven to be too steep for the Prussian T 3 vehicles originally used there . So in 1889 it was decided to build eight new machines for the 21.4 kilometer route.

The locomotives had an all control, the barrel axle was built as an Adam axle , and the steam dome was on the front boiler section. Various braking systems were also tested on the locomotives. In the redesignation plan of 1923, three locomotives were planned to be redesignated as 90 002, 066 and 067. However, these were retired by 1925.

In 1930, after taking over the traffic on the Bremen port railway, two locomotives as 90 232 and 90 233 came to the Deutsche Reichsbahn. However, these were retired in the same year.

The T 9 of Oberhessischen Railway Company was a freight train tank locomotive of the wheel arrangement C1 '. It was shortly before the transition from this state Hessian railway to the Prussian state railways in 1895 from Krauss & Comp. was built according to Bavarian models. At the Oberhessische Eisenbahn-Gesellschaft it was numbered 26. It was first named Frankfurt 1871 by the Prussian State Railways, and then from 1906 on as T 9 Frankfurt 7205.

The T 9.1 of the Prussian State Railways were freight train tank locomotives with a C1 'wheel arrangement. They were intended for service on branch lines, for freight train service on main lines and for shunting service. A total of 420 locomotives were built by various manufacturers for the Prussian State Railways and 6 for the Cronberger Railway , which had been taken over by the Prussian State Railroad in 1914.

They were classified in 1923 by the Deutsche Reichsbahn as class 90 0-2 with the road numbers 90 001 to 90 328 in their redesignation plan . In 1925 there were still locomotives with the numbers 90 001–021, 90 024–115, 90 117–122 and 90 125–231 as well as the 91 088, 91 089, 91 109–114 and 91 301 and 302 incorrectly classified as class 91. Then came the 90 234 from the Bremen port railway, the 90 235–237 from the railways of the Saar area and the 90 241–245 from the Lübeck-Büchener railway , which had ordered six new T 9.1s in 1900 and 1903 and later used four Had bought locomotives from the Prussian State Railway.

Some copies of this locomotive were given to foreign railway administrations and some came back to the Deutsche Reichsbahn as 90 246-251 during the Second World War. 4 machines, almost identical to the state railway locomotives, were manufactured by Borsig from 1903 to 1908 as KN 1–4 for the Kassel-Naumburg railway , two of which were classified as DR class 90.64 by the Deutsche Reichsbahn from 1949 onwards .

Two T 9.1s have been preserved: One in the Bochum Railway Museum as Cöln 1833, later Cöln 7270, which has been restored since November 9, 2015 and has been installed in front of the Starlight Express Theater in Bochum, the other in the South German Railway Museum in Heilbronn as Cöln 1857.

Detail of a technical drawing of the steam locomotive number 91 134 of the Deutsche Reichsbahn

The T 9.2 of the Prussian State Railways were freight tender locomotives with a 1'C wheel arrangement. They had the same area of ​​responsibility as the T 9.1. The main dimensions also largely coincided with this. The reason for their design was the fear that the running characteristics of the T 9.1 would be too poor. Therefore they got a front instead of a rear barrel axis.

The Mecklenburg State Railways received three locomotives of this type in 1920 due to a lack of locomotives. The Essen 7203 to 7205 machines were given the track numbers 772 to 774. The latter was sold on to the Nauendorf-Gerlebogker Eisenbahn-Gesellschaft in 1921 . The others were redrawn as 91 002 and 91 003 in 1925.

Of the 235 machines, 154 were later taken over by the Deutsche Reichsbahn in the 1923 redesignation plan and classified as class 91 0-1 . According to the re-labeling plan of 1925, 111 locomotives were taken over as 91 001-087, 91 090-108, 91 115 and the incorrectly classified 90 023, 90 024, 90 123 and 90 124.

The locomotives with the road numbers 91 116–121 come from the Bremer Hafenbahn (91 116) or the Saar Railways. In 1938 there were 91 131-136 from the Braunschweigische Landeseisenbahn. During the Second World War , the locomotives 91 137-149 from Poland were added.

After the war only a few copies were in service. The last machine of the Deutsche Bundesbahn was decommissioned in 1953 and the Deutsche Reichsbahn in 1966. The Reichsbahn machine 91 134 was retained. It has belonged to the Mecklenburg Railway Friends in Schwerin since August 2006. After its serviceable overhaul, it went on special trips again in mid-2009 as part of the Federal Horticultural Show (BUGA) in Schwerin until a boiler damage detected forced the locomotive on the siding. Thanks to various public funding programs in the six-digit euro range and other financial resources of the association, the Mecklenburg Railway Friends were able to have the locomotive completely refurbished in 2015 at the Meiningen steam locomotive works for the sum of around EUR 610 thousand. In the process, some technical add-on parts, such as the steam-powered bell and the steam-powered whistle, were returned to their original design, but the necessary adjustments were also made for safe operation in line with modern times. Since mid-February 2016, the machine has been fully operational again in special train traffic.

T9.3 construction drawing

The T 9.3 of the Prussian State Railways were tank locomotives that were used in both passenger and freight train traffic. A total of 2060 locomotives (including the locomotives of the East Prussian Southern Railway, which was nationalized in 1903) of this type were built for the Prussian State Railways . The Königlich Württembergische Staats-Eisenbahnen has purchased another 10 T 9 units . The Reichseisenbahnen in Alsace-Lorraine had procured a total of 132 T 9.3s . Various private railways have also received T 9.3.

The Mecklenburg State Railways were assigned three locomotives of this type in 1920 to remedy an acute shortage of vehicles. The Essen 7378, 7062 and 7073 locomotives were given the train numbers 780 to 782.

The locomotives of the type were classified in 1925 by the Deutsche Reichsbahn as class 91 3–18 and 91 20 in their redesignation plan .

The T 9.3 is a further development of the Prussian T 9.2, from which it differed most strikingly in the Krauss-Helmholtz frame used instead of the Adam's axle . This allowed the top speed to be increased to 60 km / h, and later even 65 km / h. The Reichsbahn took over a total of 1503 machines from Prussia as 91 303-1805, including ten T 9.3s, which originally came from the Reichseisenbahnen in Alsace-Lorraine ; 31 from Saarland as 91 1806–1836 and 10 Württembergische T 9 as 91 2001–2010. During the Second World War , additional locomotives were added from Belgium as 91 1837–1844.

On April 1, 1949, the Deutsche Reichsbahn took over further T 9.3s with the numbers 91 6501, 6576, 6577, 6581 and 6582 from private railways, some of which had been converted to superheated steam.

The retirement began after 1945 and ended in 1964 at the Deutsche Bundesbahn and in 1971 at the Deutsche Reichsbahn .

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 eliminated fairly soon (91 1421 1951 and 91 1314 1952). The remaining two machines 91 1207 and 91 1347 formed the ÖBB series 691 while retaining the serial numbers . Both representatives of the 691 series deployed in the St. Pölten area were retired in 1957.

In Germany, 91 319 in Münster, 91 896 II in Dresden and 91 936 in the German Museum of Technology in Berlin have been preserved. The Minden Museum Railway is rebuilding a T 9.3.
The 91 406 was brought to Nördlingen in 2015 from the Bavarian Railway Museum in Finland, where it is refurbished into a museum locomotive. 91 1770 is in the St. Petersburg Railway Museum.

The PKP used the type T 9.3 locomotives available in Poland under the designation TKi3 .
