The Lenz type bz were cogwheel locomotives that were procured by Lenz & Co. for the Görlitzer Kreisbahn .
history
The Görlitzer Kreisbahn had a short section between Königshain-Hochstein and Hilbersdorf (Kr Görlitz) with an incline of 50 ‰, which was equipped with an Abt rack system . The Maschinenfabrik Esslingen delivered in 1904 at the factory numbers 3297-3299 three locomotives, which by Lenz & Co. numbered 1 bz to 3 bz were classified. The genus bz in the labeling scheme of Lenz & Co. they received to distinguish it from the 1900 Eulengebirgsbahn supplied C1'-locomotives Lenz type z . From 1913 the locomotives were designated 1 Cz –3 Cz
When in 1922 the cogwheel operation was given up in favor of a pure friction operation, as on all such routes in Prussia, the Görlitzer Kreisbahn parked the locomotives and had them scrapped later. As a replacement, the Görlitzer Kreisbahn purchased tank locomotives of type ELNA 6 with counter-pressure brakes , which remained in use until the line was closed in 1972.
