As Sächsische IV K ( pronounced : four K), the Royal Saxon State Railways designated the four-axle narrow-gauge steam locomotives of the Günther-Meyer type with 750 mm gauge from 1900 . With 96 units, the Saxon IV K is the most popular narrow-gauge (steam) locomotive for a state railway in Germany . The Deutsche Reichsbahn assigned the locomotives to the 99.51–60 series in 1925 .

history

As a result of the steadily increasing volume of traffic on the Saxon narrow-gauge railways towards the end of the 19th century, the performance of the locomotives of the Saxon types I K , II K and III K was soon no longer sufficient. The Sächsische Maschinenfabrik then developed a locomotive with four driven axles, which had a larger boiler and a larger friction mass (based on the Saxon MI TV for standard gauge developed in 1890 ). In contrast to the previously used locomotives, these were given two motor bogies to enable them to travel on winding routes despite their length. Between 1892 and 1921 a total of 96 locomotives with the track numbers 103 to 198 were put into service. They initially received the generic designation H M T K V , which identified them as a locomotive from the manufacturer Hartmann (H) of the Meyer (M) type as a tank locomotive (T) with 750 mm gauge (K) and compound drive (V). From 1896 they were identified as K IV and 1900 as IV K , respectively. The "K" stands for "small gauge".

The IV K was used in front of both passenger and freight trains , but also mixed trains, and it proved so good that it replaced the other types of locomotive (IK, II K and III K) on almost all routes.

Five copies had to be copied after the First World War . One of these locomotives came to Serbia in 1918 , where it remained after the end of the war, the other four remained in Transylvania after being used for the army field railways , three of which became Hungarian property during the Second World War. All IV-K locomotives used on the network around Novo Swenzjany and in Galicia in the First World War in the Baltic States (in total it is said to have been more than a dozen machines) returned to Saxony before the end of the war.

In 1920 the Deutsche Reichsbahn took over the 90 machines that remained in Saxony. With the 96th IV K, which was put into service in 1921, they were given the numbers 99 511-546, 99 551-558, 99 561-579 and 99 581-608 in 1925. With the 15 five-axle army field railway locomotives acquired in 1919 (classified as Saxon class VI K), their replicas 99.67-71 and the standard locomotives 99.73-76 , mostly older IV-K machines were decommissioned in the 1930s. By 1939, 18 more machines had been deleted from the inventory. During the Second World War , twelve more machines were lost during military operations.

After the Second World War, two locomotives of the U99.5 series remained with the Czechoslovak State Railways (ČSD), four more were confiscated by the Soviet occupying forces as reparations. 57 operable machines remained in the DR fleet. Nine locomotives later came to the former Rügen Kleinbahn and the former Prignitzer Kreiskleinbahnen , where they were equipped with Knorr brakes and, in this context, received a conspicuous compressed air tank on the boiler.

The German Reichsbahn planned, which now have come to the end of life equipment by new diesel locomotives of the series V 36.48 to replace. However, since the tests with the two types did not produce satisfactory results, a total of 30 locomotives were largely overhauled between 1962 and 1967. The locomotives initially only received new boilers, later also new frames, bogies and cylinders in welded construction. A total of 23 machines received new frames. The external characteristic of the new boilers is the missing sand container on the boiler and the flattened cladding of the steam dome.

By 1973, the last non-renewed locomotives retired from service. The locomotives 99 535 ( Dresden Transport Museum ), 99 579 (Museum Rittersgrün), 99 581 (museum planned in Kirchberg) and 99 604 ( DGEG , today SSB Radebeul), which were still largely original , were secured for museum preservation, but 99 581 was in June Scrapped in Kirchberg in 1983. The decommissioning of the generally repaired and largely refurbished locomotives began in the early 1970s, starting with the machines that still had their original, riveted frames.

In mid-1991 there were still 13 IV Ks in the operating portfolio of the Deutsche Reichsbahn. As part of the alignment of the DR and DB operating numbers , these locomotives were to be given the new operating numbers 099 701 to 099 713 from January 1, 1992. However, two locomotives were sold to the Jöhstadt – Steinbach Museum Railroad in November 1991 and the 99 562 was defective, so that only ten of them were given the new operating numbers. In addition, the traditional locomotive 99 539 only rarely wore the number 099 701. In 1992/93 more locomotives were sold to clubs and to Döllnitzbahn GmbH. Several locomotives came to Deutsche Bahn AG on January 1, 1994, but the locomotives were no longer used as planned at that time.

commitment

In the course of time, the IV K were used on all narrow-gauge lines in Saxony. In the 1980s, they still handled the entire volume of traffic on the Wolkenstein – Jöhstadt and Oschatz – Mügeln – Kemmlitz routes .

During the First World War , some locomotives were also used for the army field railways, such as the 132 (later 99 539) with about a dozen other IV Ks at the First Company for Supply Railways in Novo Swenzjany in what is now Lithuania .

From the 1950s onwards, some locomotives were also used in the Prignitzer network and on the Rügen narrow-gauge railways .

The 99 554, which remained in the re-established Czechoslovakia in 1945 , initially ran on the narrow-gauge railways Jindřichův Hradec – Obrataň and Jindřichův Hradec – Nová Bystřice in South Bohemia, until it was sold to the cement factory in Králův Dvůr in 1951 . Until it was shut down in 1956, it ran on the Králův Dvůr – Koněprusy industrial railway .

Preserved locomotives

A total of 22 locomotives of the Saxon class IV K have been preserved to this day, some of them operational. In addition to the Saxon Museum Railway Associations , the Sächsische Dampfeisenbahngesellschaft (formerly BVO Bahn) and Döllnitzbahn GmbH also have class IV K locomotives for special missions in front of museum trains.

In some cases, the previous numbers were still attached to the vehicles instead of the current numbers. Above all, the 099 operating numbers , which were introduced in 1992 with the joint numbering plan of the two German state railways, were only worn briefly by the DR and DBAG. Locomotives that were not in the DR operating portfolio at the time the common numbering plan was introduced were not assigned 099 operating numbers. These numbers were not popular with the later operators and railway enthusiasts, as they do not allow any conclusions to be drawn about the DR numbers. Today they are no longer in use.

With the exception of the 099 numbers, all other numbers are still used today, and some of the locomotives also have the green paint of the Saxon State Railways.
