Data from Wiener (1930). Works numbers were 1781-1784 in 1891.
This semi-articulated design used the pantograph action of the two end driving axles (known as the Klose system). For a full description of the mechanism, see the Wurttemburg F1 0-6-0. In this entry, note the compact dimensions and the good balance between boiler and grate, heating system and engine size.
