As genus IK ( ie : one K) designated the Royal Saxon State Railways six-coupled narrow gauge - steam locomotives with 750 mm gauge. The Deutsche Reichsbahn classified the remaining locomotives in the class 99.750–752 using the 1925 redesignation plan .
history
From 1881 onwards, numerous narrow-gauge lines were opened in the Kingdom of Saxony , some of which showed a course with many inclines and curves. For this purpose, the Royal Saxon State Railways procured 39 small, triple-coupled tank locomotives from the Sächsische Maschinenfabrik formerly Richard Hartmann AG in Chemnitz . From 1890 another five copies were delivered to the private Zittau-Oybin-Jonsdorfer Eisenbahn-Gesellschaft (ZOJE), which were taken over by the State Railroad in 1906 and in 1907 were given operating numbers 49-53 by the State Railroad.
The locomotives built for the state were initially run within the class H V TK , which was changed to K I in 1896 and I K in 1900 .
During the First World War , 20 locomotives were in use on the Heeresfeldbahn . Five of them remained in Poland in 1919. In the course of the Second World War , two of them were added to the inventory of the Deutsche Reichsbahn and designated as 99 2504 and 99 2505 respectively. They remained on their Polish routes and were returned to the Polish State Railways (PKP) after 1945 . They were scrapped in the Gdansk area until 1970.
39 locomotives were still part of the Deutsche Reichsbahn in 1920 . The new numbers 99 7501 to 99 7527 were provided in the 1925 redesignation plan. A little later, however, all of the locomotives still owned by the state railways in Saxony were decommissioned.

With the increasing volume of traffic, the performance of the IK was soon no longer sufficient and - where the tracks allowed it - they were replaced by newer, more powerful locomotives such as B. the genus IV K replaced. In order to be able to use the available I K more effectively, the four first-built units were experimentally combined into two double locomotives in 1913 . For this purpose, the rear wall of the locomotive's cab was removed and two locomotive cabs were coupled to each cab. The locomotives were given a common controller, but the controls remained separate. The converted locomotives received the class designation II K with a second occupation. It was planned to convert further locomotives in this way, but due to the First World War (keyword lack of locomotives due to the loan of vehicles to the Heeresfeldbahnen) and the unpopularity with the staff as well as the inadequacies in operation, this project was abandoned.
The first locomotive emerged from the I K with the track numbers 1 and 4 and was given the number 61 A / B. The second locomotive was the 62 A / B, which emerged from the I K No. 2 and 3. However, this was separated again in 1916 due to a lack of locomotives; the individual vehicles ran again under their old numbers.
For the II K 61 A / B the new number 99 7551 was planned in 1923, but it was retired in 1924.
technical features
A riveted Crampton boiler, made in two shots, was installed as a steam generator. Two non- suction Friedmann injectors were used to feed the boiler . The chimney was equipped with a Kobel spark arrester, the first series had this in a conical design.
A two-cylinder engine with Allan controls served as the steam engine and drove the third coupling axle. The axles were rigidly mounted in the frame. The track numbers 27 to 30 were given a Klien-Lindner hollow axle at the front for better archability .
The locomotive was braked using a throw lever brake. To brake the train, the cable reel for the jack brake on the rear wall of the driver's cab was used.
The water and coal supplies were housed in side boxes next to the boiler.
commitment
The type I K was once used on almost all Saxon narrow-gauge railways . After the building of the more powerful classes III K and IV K, the I K were mainly used on routes with little traffic. The last locations were the Zittau train station and the Kohlmühle – Hohnstein , Klingenberg-Colmnitz – Oberdittmannsdorf routes and the network around Mügeln .
After their retirement, seven I K were sold to industry as factory locomotives. The locomotive with the number 12 was sold to the Schmiedeberg ironworks in 1923, where it was in service until 1963. In 1964 the machine was scrapped.
After 1945, the Polish State Railways used the last two locomotives that remained in Poland on the remainder of the Zittau – Hermsdorf line that fell to Poland.
The construction of a new IK as a museum locomotive
As part of the opening event for the anniversary "125 years of narrow-gauge railways in Saxony", the Association for the Promotion of Sächsischer Schmalspurbahnen eV (VSSB) announced on January 12, 2006 the project to build a new locomotive of the class I K. Since the former manufacturer no longer exists the building was launched as a "network project". With the support of sponsors (donor shares were issued for the project) and companies, a large part of the components could be manufactured inexpensively. The Meiningen steam locomotive plant was selected for the overall assembly and manufacture of the boiler .
A budget of 1.5 million euros was planned for the new building project. Since many of the components were provided free of charge by the companies involved, the calculated total costs fell to around one million euros. In November 2008, most of the assemblies - such as the driver's cab, steam boiler and chassis parts - were completed. In contrast to the riveted locomotives of the state railway era, the new building was largely made as a welded construction, so visible rivet heads are dummies. The machine was also equipped with a Körting suction air brake. On January 16, 2009, final assembly began in the Meiningen steam locomotive works and was completed in June 2009. In continuation of the historical series of numbers (which ended with road number 53), the newly built locomotive was given the number 54.
She drove the first few meters on her own on June 16, 2009 in Meiningen. On July 4, 2009, the new locomotive was christened and officially put into service in the narrow-gauge area of Radebeul Ost station . The new locomotive 54, which bears the number 99 7528, was initially at home on the Pressnitz Valley Railway in Jöhstadt. On August 30, 2009, the locomotive was used as scheduled for the first time in front of the museum trains between Jöhstadt and Steinbach . After the dissolution of the Association for the Promotion of Saxon Narrow Gauge Railways , the Saxon Narrow Gauge Railways Foundation has owned the locomotive since 2015 and has housed it with the Saxon-Upper Lusatian Railway Company (SOEG) from summer 2015 . This does not change anything in the previous operating concept.
Since 2016, IK No. 54 has had a suitable historic train, the IK train, consisting of two-axle passenger cars, with which trips from around 1900 can be offered. With this train, which is based in Zittau, journeys can be offered on all existing narrow-gauge railways with a gauge of 750 mm.
