The Saxon State Railways designated five-coupled narrow-gauge steam locomotives with a gauge of 750 mm as class VI K (pronounced: six K ) . The Deutsche Reichsbahn (DR) assigned the locomotives from 1925 to the 99.64-65 series and procured several replica series from 1923 to 1927, which were classified within the 99.67-71 series.
technical features
The VI K were five-coupled superheated steam locomotives. The first, third and fifth wheelset of the locomotive was movably mounted on the sides ( Gölsdorf axis ), with a reset device being installed to guide the first and fifth axes. This consists of a steel disc that is attached to the center of the wheelset shaft and is centered by spring-loaded pressure pieces. With this construction it was possible to drive through curved tracks up to a radius of 50 m. The drive axle was originally the fourth axle, the third axle served as the drive axle on the locomotives that were renewed at the DR. The locomotives had Schmidt smoke tube superheaters . The brakes were a suction air brake type Körting, the cable reel for the jack brake and, on the newly built locomotives, a compressed air brake type Knorr as an additional brake. The Württemberg locomotives only had a Knorr type compressed air brake.
history
Original design
The locomotives were originally developed for the army administration . 15 pieces were built by Henschel & Sohn , Cassel. They should be used on Polish narrow-gauge lines. Due to the peace treaty of Brest-Litovsk , an operation in the east was no longer possible. In 1919 the Saxon State Railways bought all the machines in the series for their narrow-gauge lines. They were given the Saxon railway numbers 210 to 224. The Deutsche Reichsbahn took over all vehicles as the 99.64–65 series with the numbers 99 641 to 99 655.
The machines with the numbers 99 650 and 99 651 came to the Reichsbahndirektion Stuttgart at the end of 1928 , which they used at the Ochsenhausen locomotive station, which is subordinate to the Aulendorf depot. Both locomotives were the main vehicles of the Württemberg narrow-gauge railway Biberach - Warthausen - Ochsenhausen until passenger traffic was discontinued on May 31, 1964 . Then they came to the Bottwartalbahn .
The vehicles with the numbers 99 643 and 99 647 came from Saxony to Austria in July 1944, the former immediately to the Waldviertler Schmalspurbahnen , at least 99 647 initially to the Vellachtalbahn in Carinthia. After both VI K were there for a short time. From August 1944 both Saxon VI Ks are said to have been stationed in Gmünd (main depot of the Waldviertel narrow-gauge railways). From there they came to the Soviet Union as reparations in December 1948.
The 99 649 was already lost in the Second World War; the 99 641, 645 and 652 had to be handed over to the Soviet Union after 1945 .
The last two copies on the Deutsche Bundesbahn, the Bottwartalbahn vehicles , were retired on July 31st and September 29th, 1969. The latter, number 99 651, was then erected as a memorial in Steinheim an der Murr . It was the only narrow-gauge steam locomotive of the German Federal Railroad that still had an IT company number .
Replica locomotives of the Deutsche Reichsbahn
The locomotives of the class 99.67–71 of the Deutsche Reichsbahn were replicas of the Saxon class VI K, which were built between 1923 and 1927. They had the company numbers 99 671 to 99 717. The 47 locomotives were built by Henschel & Sohn (13 locomotives), the Sächsische Maschinenfabrik formerly Richard Hartmann, AG Chemnitz (22) and the Maschinenbau-Gesellschaft Karlsruhe (12).
A number of these locomotives were also used in Württemberg on the Bottwartalbahn and the Zabergäubahn : the 99 679 to 99 683 were immediately delivered to Württemberg, later 99 671, 672, 698, 701, 704 and 716 were moved from Saxony to Württemberg. Most of these machines were in service with the Deutsche Bundesbahn until around 1965, and in 1967 the 99 704 was the last to be retired.
Except for a few details, the replicas hardly differed from their retrofitted predecessors. From the outside, the replica locomotives were mainly recognizable by the less rounded cladding of the steam dome.
In 1927, the Esslingen machine factory built four meter-gauge locomotives of this type, which were classified as the 99.19 series on the Deutsche Reichsbahn.
In the 1960s, the Deutsche Reichsbahn (DR) subjected the seven locomotives 99 673, 678, 685, 692, 703, 713 and 715 to a general overhaul (GR). New welded boilers were installed. Some of them also received new water and coal boxes.
In 1964/65, seven other locomotives in the Görlitz RAW received a major overhaul - colloquially often referred to as "reconstruction", although de jure there was no reconstruction program for narrow-gauge locomotives and wagons in the GDR. The major part of the renovation was a disguised new construction program. The - de facto newly built - locomotives had new boilers, welded driver's cabs and storage containers based on the model of the standard locomotives, as well as new frames with a uniform center distance of 1,000 mm. In the new building, the drive was relocated from the fourth to the third coupled wheel set, which was firmly mounted in the frame. The second and fourth wheelsets could now be moved. The new locomotives also had suction and compressed air brakes as locomotive brakes, while the Körting type suction air brakes or the jack small brake were used to brake trains. This new building concerned the three original VI K 99 648, 653 and 99 654 as well as the four replica locomotives with the numbers 99 687, 694, 696 and 706.
In 1970, the locomotives that remained in the Reichsbahn operations portfolio were given a new number by placing a 1 in front of the serial number, which ended with an EDP control number added with a hyphen.
Both the seven refurbished and the seven newly built VI Ks were taken out of service by the Dresden Railway Directorate by 1975.
Use abroad
One of the locomotives, the 99 702, remained in Frýdlant v Čechách ( Friedland in Bohemia ) after the Second World War . After a repair, it was used from 1948 by the Czechoslovak State Railways (ČSD) as the U58.001 on the narrow-gauge railway Třemešná ve Slezsku – Osoblaha . In 1957 it came back to Frydlant, where it was used until 1960 in train traffic on the narrow-gauge railway Frýdlant v Čechách – Heřmanice . At the end of 1962 it was retired and scrapped a little later.
Preserved locomotives
The 99 651 is the last remaining locomotive of the original series. On June 10, 2016, it was brought from Steinheim an der Murr to sheltered storage at the Öchsle Museum Railway to Ochsenhausen. In a first step, it should be made rollable again.
The locomotives 99 713 and 715 were also preserved, initially in Radebeul-Ost. 99 713 was kept operational by the DR as a traditional locomotive, 99 715 served as a spare part donor and was officially a monument locomotive in front of the museum train in Radebeul Ost. In 1992, 99 713 was given the new company number 099 720 on paper, but it was rarely used. 99 715 was sold in 1991 to the later GbR 99 715 Wilsdruff and finally refurbished until 2003. She has been employed by the Preßnitztalbahn since 2004 and can be seen in operation. The 99 713 went to today's Sächsische Dampfeisenbahngesellschaft (SDG) in 2004 . It was transferred to Oberwiesenthal in October 2015 after a long period of inactivity, received a general inspection there and has been operational again since July 2017.
99 716 was in the Güglingen local history museum for 25 years and was taken over by the Öchsle Museum Railway in 1993 as a loan from the Nuremberg Transport Museum . From 1997 she was in use again. In the summer of 2008, Öchsle-Bahn AG acquired the steam locomotive from the DB Museum in Nuremberg. It has not been operational since December 2011 due to expired deadlines; Work has been underway for a new general inspection since 2017.
