Harzer Schmalspur Bahnen 0-4-0 Locomotives in Germany
Class Details by Steve Llanso of Sweat House Media
Class K22.12 / BR 99.52 (Locobase 3782)
Data from [

Although 13 years later than the K22.10, this engine had no superheater and a lower boiler pressure. Could the K22.10 have demanded too much maintenance effort?
