7838/1943), Rozbark colliery, date unknown. Photo by Tadeusz Suchorolski (collection of Mariusz
Furtek and Jacek Chiżyński

TKw3 locomotives are extremely rare.
The sole surviving SäStB class XI HT engine: 94 2105 (Hartmann 4561/1923), photographed at
the Eisenbahnmuseum Schwarzenberg on June 2, 2001. Photo

The same source and the same engine, date unknown (possibly 1988).
Note feedwater heater between smokestack and first
boiler dome, which was fitted to some XI HTs.
Factory photo of the SäStB 2033 (Hartmann
3665/1913), later 94 2021. After WWII this locomotive was taken over by
Czechoslovakian railways and re-designated 516.0500; it remained in use until
July 1956. TKw3-1 belonged to the same production batch. Source: Lokomotiv-Archiv Sachsen 2 (see References).

withdrawn in October 1973. Photo by Reiner Preuss (from my collection).

The
story of tank locomotives classed TKw3 is somewhat complex, as they belonged
to three distinct types. Between
1908 and 1923 Sächsische Maschinenfabrik
of Chemnitz, known as Hartmann,
built 163 class XI HT superheated freight tank locomotives for the Royal Saxon State Railways (SäStB). First
batch, delivered between 1908 and 1909, comprised eighteen examples, numbered
1521 through 1538 and in 1916 re-numbered 2001 through 2018. It was followed
in 1910 by ten engines, numbered 1675 through 1684 (later 2019 through 2028),
which were lighter by 3.2 tonnes and featured
shortened boilers and cylinders reduced in diameter from 620 to 590 mm. These
measures had been introduced in order to reduce axle load. Production of the
original heavier version was re-commenced in 1913, but with numerous
modifications: length increased from 12 080 mm to 12 390 mm,
modified water boxes and maximum speed increased from 45 to 60 km/h. These
locomotives were numbered from 2029 onwards. In 1915, starting from No. 2037,
overall length was again increased to 12 560 mm, due to enlarged coal
box. Last nine examples, built in 1923, were not assigned SäStB service numbers, due to
merging of all German state railways into DRG.
Two class XI HT locomotives were lost during the war and thirteen went to
France as a part of war reparations (two of them returned in 1941). The rest
were impressed into DRG and classed
9419 (lighter variant, withdrawn between 1932 and 1934), and 9420-21
(heavier variant, irrespective of version). The latter class, apart from a
few examples that were taken over by Austrian, Czechoslovakian and Polish
railways, later served only with DR.
A few survived into 1970s and the last one, 94 2105 (originally SäStB 2129, Hartmann 4561/1923) was withdrawn in
October 1978; this locomotive has been preserved and can be seen at the Eisenbahnmuseum Schwarzenberg. One
class XI HT locomotive (94 2019, ex SäStB 2013, Hartmann
3663/1913) was impressed into PKP
in 1945 and designated TKw3-1. I have no information on its subsequent
service, which was presumably not very long, and ultimate fate. Apart
from class XI HT, Hartmann built
also a few 0-5-0 tank engines, ordered by Bergwerk-Verein Zabrze O/S and operated by various
collieries. Three (service numbers 1, 2 and 3) were delivered in 1905; No. 7
followed in 1913. They were smaller and lighter than XI HT and ran on
saturated steam. After WWII all were taken over by Polish mining industry.
They were re-numbered TKw3-221 (Pokój colliery), TKw3-222 (assignment unknown), TKw3-223 (Andaluzja colliery)
and TKw3-227 (Kleofas
colliery, scrapped in May 1970), the last digit corresponding to the original
service number. Detailed information
on their service is lacking and none has been preserved. Finally,
in 1943 Grafenstaden
(SACM) delivered eight 0-5-0 tank
locomotives for Oberschlesische Hydrierwerke AG,
to be used at the large synthetic petrol factory built in Blechhammer
(today Blachownia) and numbered 11 through 18.
After the war No. 15 was taken over by VEB
Kombinat Espenhain in
Eastern Germany and was later used as a stationary boiler at the Leipzig-Engelsdorf depot. No. 12 was transferred to an
unidentified Polish industrial plant; details are lacking. Ultimate fate of
No. 16 is unknown; it seems possible that it was destroyed at the factory premises,
which were heavily bombed by USAAF
in late 1944. The remaining five locomotives were initially taken over by PKP and numbered TKw3-2 through 6.
They were assigned to the Katowice regional management and later, possibly
between 1949 and 1951, transferred to collieries. Again, very little is known
about their service. TKw3-4 (re-numbered TKw3-7839, Grafenstaden 7839/1943) was
withdrawn in June 1962 and scrapped. TKw3-6 (re-numbered TKw3-7843, Grafenstaden
7843/1943) survived in service until 1972. A derelict TKw3 (number unknown)
was photographed at the Sośnica colliery in 1980 – this photo can be seen at www.cyfrowa.stacjamuzeum.pl.
According to www.wrphoto.eu, TKw3-8378
(ex TKw3-3, Grafenstaden
7838/1943) underwent major repair at the ZNTK
Bydgoszcz repair establishment (present-day Pesa) and was withdrawn in late
1970s or early 1980s – possibly the above-mentioned photo is of this particular
engine. I have not managed to find technical data of this type, so any hint
is most welcome. No example has been preserved. Main technical data –
TKw3-1*)
