Württemberg Tssd
Encyclopedia
The Württemberg Tssd was a class of German, narrow gauge, steam locomotive
operated by the Royal Württemberg State Railways
. They were initially deployed on the Öchsle Railway in 1899 between Biberach an der Riß
and Ochsenhausen
. In addition they worked the Federsee Railway between Schussenried and Riedlingen
, the Zabergäu Railway
between Lauffen am Neckar and Leonbronn and the Bottwar Railway between Marbach am Neckar
and Heilbronn
Süd. A total of nine units were delivered in three series of three engines in 1899, 1901 and 1904 with railway numbers 41–49. They were initially classified as Tss locomotives and later as Tssd 41–49.
T is the abbreviation for tank locomotive
, ss means that it is a narrow gauge
locomotive with a rail gauge
of 750 mm, and the letter d, added later, was the abbreviation for duplex locomotive
, because the steam was expanded twice, first in the high-pressure cylinders and then in the low-pressure cylinders. Today duplex locomotives are described as compound locomotive
s.
All the engines were taken over by the Deutschen Reichsbahn-Gesellschaft
and given the numbers 99 631 to 99 639. After the Second World War four engines were still in service. They were retired as follows:
Two locomotives, numbers 99 633 and 99 637 have been preserved. Locomotive 99 633 was under the ownership of the German Railway History Company (DGEG) and was loaned to the Öchsle Schmalspurbahn (Öchsle Narrow-Gauge Railway) and displayed in the Ochsenhausen shed, its original home. In 2007 the society bought it outright. Since the very first transmission of the SWR
television programme, Eisenbahn-Romantik
, it has featured in the introduction and the programme's logo.
Number 99 637 is on display as a monument at the former station forecourt in Bad Buchau
, its last home station.
The engines carried 2.5 m³ of water (the third series had larger water tanks with a 3.0 m³ capacity) and 1.0 tonne of coal
. The maximal train load was 140 t on an incline of 1:40.
