Class Tss 3 of the Königlich Württembergische Staats-Eisenbahnen (KWSt.E.) consisted of four three-axle tank locomotives with a gauge of 750 mm, which were procured in 1896 for the Zabergäubahn (Lauffen-Leonbronn) and Federseebahn (Schussenried-Buchau-Riedlingen). They had a Klose engine .
history
The locomotives designed by Adolf Klose had the track numbers 21 to 24. They were manufactured with the serial numbers 2794 to 2797 by the Esslingen machine works . Locomotives 21 and 22 were planned for the Zabergäubahn, and numbers 23 and 24 for the Federseebahn. They were mostly used in front of passenger trains. There is also information for the years between 1896 and 1901, according to which numbers 23 and 24 were stationed in Beilstein and traveled on the Bottwartalbahn .
From 1899 the first Tssd appeared , a series of more modern mallet locomotives with a gauge of 750 mm. They took over a good part of the train subsidies and were still procured. The KWSt.E. However, it did not part with the Tss 3, because the Deutsche Reichsbahn , established in 1920, initially provided for the series numbers 99 501 to 504. The redrawing itself can no longer be determined and probably no longer took place. Overall, very little is known about the history of the Tss 3 in use. By 1927 at the latest, all locomotives were scrapped.
technology
The Tss 3 had a riveted sheet metal outer frame that was stiffened with cast steel cross struts. The controls , the drive and coupling rods as well as the length compensation of the Klose engine were arranged on the outside. The cylinders lay on the sheet metal next to the smoke chamber and each worked on a two-armed lever (black in front of the light, parallelogram-like rods in the work picture), which in turn acted on the second drive axis , which was firmly mounted in the frame . The coupling rods were able to adapt to the track curves thanks to their parallogram-like arrangement. So the first and last axis were swiveled to the track curve radius. However, the Klose engine was very complex to design and maintain.
The Tss 3 had a Westinghouse - Compressed air brake for the train and a spindle brake Exter'sche extending obliquely on both sides worked from above on the driving axle.
Upon delivery, the locomotives had a Kobel chimney as a spark arrester . The cab was similar to the longer, four-axle Tss 4
