The locomotives of the Tssd series were Mallet - steam locomotives for 750 mm gauge of the Royal Württemberg State Railways .
history
The locomotives were initially used at Öchsle between Biberach an der Riss and Ochsenhausen from 1899 . They were also used on the Federseebahn between Schussenried and Riedlingen , on the Zabergäubahn between Lauffen am Neckar and Leonbronn and on the Bottwarbahn between Marbach am Neckar and Heilbronn Süd . A total of nine vehicles in three series of three pieces each were delivered in the years 1899, 1901 and 1904 with the track numbers 41-49, which were initially referred to as Tss and later as Tssd 41-49.
T is the abbreviation for tank locomotive , ss means that it is a narrow-gauge locomotive with a gauge of 750 mm, and the later added d serves as an abbreviation for duplex locomotive , a locomotive with two engines. These engines worked as a compound engine ; the steam is released twice, first in the high-pressure and then in the low-pressure cylinders.
All machines were taken over by the Deutsche Reichsbahn-Gesellschaft and were given the numbers 99 631 to 99 639. After the Second World War , four locomotives were still available, all of which now belonged to the Deutsche Bundesbahn . They were retired as follows:
- 99 638 - October 26, 1954
- 99 639 - November 27, 1956
- 99 637 - March 25, 1965
- 99 633 - March 18, 1969
The machines carried 2.5 m³ of water (the third series had enlarged water tanks with 3.0 m³ capacity) and 1.0 ton of coal . The maximum trailer load (of the wagon train) is specified as 140 t with a gradient of 1:40.
Preserved locomotives
The two locomotives 99 633 and 99 637 , both of which were last used on the Federseebahn, have been preserved for posterity .
The locomotive 99 633 was acquired by DGEG in 1970 and used on the Jagsttalbahn . It has been owned by Öchsle Schmalspurbahn e. V. and was exhibited in the engine shed in Ochsenhausen (their first home). It was already operational between 1985 and 1990 (still operational) and since 2002 on loan from the Öchsle. In 1985 she had the honor of leading the first Öchsle museum train . It can be seen in the opening credits of the program and as its logo since the SWR television program Eisenbahn-Romantik was first broadcast . In 2011, the refurbishment began with the manufacture of a new boiler at Tschuda in Graz based on the original boiler. The first test run on the Zillertal Railway took place on November 22nd .
The locomotive 99 637, on the other hand, is externally restored as a technical monument on the former station forecourt in Bad Buchau , its last home.
