Hanichener Kohlenbahn 4-4-0 Locomotives in Germany

Class Details by Steve Llanso of Sweat House Media

Class VIIIb T (Locobase 3850)

Data from Windbergbahn Railway website at [] . supplies the limited information. See also "Kohlenbahnlokomotive (sSchsische Gattung H VIIIb T)" on the

Die Windbergbahn - SSchsische Semmeringbahn website at [], last accessed 16 July 2022. Works numbers were 77-79 in 1857, 118 in September 1858, and 271 in 1866. (Production lists ascribe the order to the Albert-Bahn.

Based on Locobase's very limited German, it seems that these engines -- ELBE, WINDBERG, STEIGER, FREIBERG, and BURGK (which had a slightly longer wheelbase at 8.14 ft) -- came to the Windberg line by 1857.

Later information from the 2022 link told much more about this unusual locomotive. Unlike many 2/4 gek. locomotives of the time, this engine used a leading bogie to negotiate curves as tight as 57 metres on this coal road. (Tests using 2-4-0 engine Friederich August "failed miserably" as Google translates the account.)

The small locomotive showed its cylinders and Allan valve gear outside of the boiler and smokebox. Two safety valve stands of identical shape sat over the boiler's middle and the firebox.

Chief Engineer Guido Brescius successfully coordinated the requirements of his railway and Hartmann's production capability and early experience with the first three engines showed that the locomotive could haul ten loaded wagons down the valley and fifteen empty one back up. Traffic grew quickly and the HK bourght
