Württemberg Fz

The Württenberg Fz was a class of nine 2-6-0T rack locomotives of the Royal Württemberg State Railways (Königlich Württembergische Staats-Eisenbahnen, K.W.St.E.).

591 to 596 and 599) were taken over by Deutsche Reichsbahn and were placed in class (Baureihe) 97.3 in their 1925 renumbering plan.

The first four locomotives were named ACHALM, GRAFENECK, LICHTENSTEIN and MÜNSINGEN and were used on the Honau–Lichtenstein rack railway line.

The small gear itself was driven by the inner two cylinders of the four-cylinder steam engine.

The valve gear and rack system drive were so complex and prone to failure that the locomotives were withdrawn and scrapped by the Deutsche Reichsbahn by 1930.
