The Württemberg T 9 was a steam locomotive and was manufactured in 1906 and 1907 by the Esslingen machine factory based on the model of the Prussian T 9.3 . There were only minor deviations from the Prussian variant. They were used for freight trains and passenger trains on branch lines. At the Deutsche Reichsbahn it was included in its numbering plan as class 91.20 . The locomotives were taken out of service by the Deutsche Bundesbahn by 1950 .
