The Württemberg Tss 4 was a class of three 750-mm gauge
History
The three Tss 4 locomotives were given the fleet numbers 11, 12 and 13; they also carried names: no. 11 GROSSBOTTWAR, no. 12 OBERSTENFELD and no. 13 BEILSTEIN. They were built by Maschinenfabrik Esslingen, who assigned serial numbers 2638 to 2640. They entered service on 10 May 1894 with the opening of the section from Marbach to Beilstein. When the entire route was commissioned on 1 December 1990, they were then used to Heilbronn Süd. At the beginning they managed the traffic alone. Quiet running and traction were convincing. From 1899 the Tss 4s got company from number 42, a Tssd class Mallet tank locomotive. More Tssd locomotives were procured for the Bottwartalbahn, which meant a departure from the maintenance-intensive Klose drive system. Nevertheless, the three Tss 4 remained in service until the early days of the Deutsche Reichsbahn, even if in the 1920s the locomotives were often stored or under repair because of their worn out Klose drive. The arrival in 1923 of the newer Saxon VI K sealed the fate of the Tss 4 on the mainline. Numbers 12 and 13 received their Reichsbahn numbers 99 621 and 99 622. Number 11 was not renumbered and was stored in 1923. The other two locomotives were stored in 1926. Number 11 had been struck-off the roster by 1925, the other two locomotives were retired in 1928, and then scrapped.
Technical features
The three tank locomotives were derived from the
The cab was open at the sides and at the back. In order not to expose the locomotive crew to wind and weather when reversing, the locomotives could be turned on the turntables in Marbach and Heilbronn-Süd and therefore always drove with the chimney leading. The water tanks on the side of the boiler reached up to the smokebox. Coal was carried in the driver's cab. The locomotives carried 3.04 m3 (670 imp gal; 800 US gal) of water and 1.0 tonne (2,200 lb) of coal. On delivery, the locomotives had Kobel chimneys to suppress flying embers. They were later replaced by tall, conical chimneys.
The locomotives had a riveted plate metal frame. The three-ring long boiler had a distance of 3.30 m (10 ft 10 in) between the tube plates. The steam dome was on the first boiler ring, the sand dome on the second. There was a Ramsbottom safety valve that was initially located on the firebox inside the cab. It was later installed on the boiler behind the steam dome.
