Saechsischen 0-10-0 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class VI K / 99 64-65 (Locobase 7463)

Several sources of data including the Wikipedia entry [link][link], [link] (both accessed 25 Feb 2006). The greatest detail is available at [link]

The first fifteen of these ten-coupleds were originally built for the German Army railways by Henschel & Sohn and had been designated for service in Poland in the Thorn and Zamosz districts; their numbers were 7525H-7539H (Heeres - Army). The first, third, and fifth axles enjoyed some lateral play (30 mm/1 1/4") on the outer two, 20 mm/3/4") on the middle axle) while the drive was on the fourth axle.

With the Armistice, however, the need for military locomotives greatly diminished and the K.SSchs.Sts.E.B took the class as their VI K. Although early operations revealed a problem with derailments, the relatively high power of these little freight haulers won over their operators and the entire class was taken into the DRG in 1925.

Further orders came to Henschel & Sohn, Richard Hartmann of Chemnitz, and MBG of Karlsruhe. These engines differed from the earlier locomotives primarily in weighing a bit more:

Hartmann 1927 4665-4674 99 708 - 99 717

After World War II, 27 carried on in East German service. Another 10 operated in Baden and Wurttemberg until the mid-1960s

The last two to leave active service of any kind were retired from East German service in July and September 1969.


Class XI HT / BR 94.19 (Locobase 5761)

Christian Lindecke [link] (visited 21 December 2003) for data, supplemented by Albert Gieseler at [link], last accessed 8 May 2011.

Built to operate over lighter rail than the XI HTs first delivered in 1908, this class had smaller Belpaire fireboxes but the same large steam domes. Apparently the exchange of lower axle loading for less power wasn't worth it, because these were the only ones built to a 15-tonne axle loading. One was lost in World War One, another was yielded up as reparation, and the other 8 rolled into the DRG system as 94.1901-1908 in 1923.


Class XI HT / BR 94.20-21/DR 94.2 (Locobase 5760)

Christian Lindecke [link] (visited 12 December 2003) for information and data from the US Military Railway Service Equipment Data Book for German Locomotives supplied by Allen Stanley from his extensive Rail Data Exchange in March 2004. See also Albert Gieseler at [link] (last accessed 8 May 2011) for slightly higher heating surface values.

These K.Sachs.Sts.E.B. engines were similar to the Prussian T16s. They had Belpaire fireboxes, large steam domes, riveted plate frame.

Constructed in batches in 1908, 1909, 1913-1919. Further construction came in the early 1920s in part to offset locomotives delivered to Allied powers as war reparations. When the DRG was formed in 1923, all of the locomotives were taken over. More than 100 survived the Second World War and continued in service, particularly in East Germany. The last of the latter were retired in 1978.


Class XI V / BR 57.0 (Locobase 7806)

Data from Christian Lindecke [link] (visited 30 August 2006)

This class -- a saturated 2-cylinder, cross-compound -- was one of three variants produced for the Saxon State railways and was by far the most numerous. The other two were the XI H, twelve locomotives with a 2-cylinder, simple-expansion, superheated layout (later the DRG's 57 101-105), and the XI HV, like the V (verbund) but with superheating.(18 later took BR 57 201).
