The locomotives of type C of the Royal Württemberg State Railways were express locomotives with the wheel arrangement 2'C1 '( Pacific ). The C was the smallest 2C1 regional railway locomotive. It was a design by Eugen Kittel .
technology
The 41 vehicles were built between 1909 and 1921 by the Esslingen machine factory. From the beginning they were designed for the topography of Württemberg and therefore had drive wheels with a diameter of only 1,800 mm. The locomotives were, although they were among the smallest machines of the type 2'C1 ', economical and at the same time very powerful. The machines had a four-cylinder compound engine, all four cylinders acted on the second, cranked coupled axle.
The appearance of the locomotive is relatively unusual. The external subframe to support the sheet metal frame with the wheel arches behind for the coupling axles as well as the aerodynamically shaped driver's cab, which is similar to that of the Bavarian S 2/6 , are striking . The conical smoke chamber door also supported the streamlined impression. The locomotive was also called "The beautiful Wuerttemberg woman".
The vehicles were equipped with wü 2'2'T 20 and wü 2'2'T 30 tenders .
Reichsbahn
After the First World War, three machines had to be handed over to France and one to Poland. The remaining 37 were taken over by the Deutsche Reichsbahn as class 18.1 . There they were given the road numbers 18 101-137 in 1926.
Federal Railroad
When the Deutsche Bundesbahn was founded in 1949, it had 23 operational locomotives of the 18.1 series. In Heilbronn , 18 were 101, 102, 117, 118, 120, 126, 128, 131, 132, 133 and 136 located in Ulm 18103, 104, 105, 107, 108, 109, 110, 112, 113, 122, and 123. From Heilbronn, a pair of express trains between Stuttgart and Würzburg as well as express and passenger trains between Heilbronn, Mannheim and Stuttgart were hauled. In addition to a pair of express trains between Ulm and Friedrichshafen, the Ulm locomotives mostly hauled passenger trains between Ulm and Aalen . At the end of May 1952, the Heilbronn machines were relocated to Ulm. In 1952 two, eleven in 1953 and eight in 1954, class 18.1 locomotives were z-put and then retired and scrapped. In 1955 only 18 136 and 18 133 were still operational. The last performance of a C was 18 133 on February 13, 1955 with an express train from Immendingen to Ulm. No copy of the Württemberg C has been preserved.
