Ruegener Kleinbahn 0-4-0 Locomotives in Germany
Class Details by Steve Llanso of Sweat House Media
Class 1 (Locobase 9585)
Data from [
] (Lenz-Types 'n' (Ru.K.B 1n bis 6n), last accessed 28 September 2008.
Vulkan delivered these to the Rn.K.B.as a batch. Three of them (1, 4, 5) were retired in the 1920s and 2 was withdrawn in 1932. The other two survived World War II only to be scraped in 1947. In all of that time, they were never placed in a class by the DRG.
Class 7 (Locobase 9586)
Data from [] (Lenz-Types 'n' (Ru.K.B 1n bis 6n), last accessed 28 September 2008.
A year after Vulkan delivered the first six Ru.K.B. tanks (Locobase 9585), it added this pair, which were slightly larger in all respects. Locobase observes that the profile shown on the Ru.K.B. features a steam dome with a pointed safety valve on top resembles the "pickelhauben" helmet adopted by the Imperial German army.
#8 was retired from the Uranbergbau Wismut (the uranium-mining complex in Eastern Germany) in the late 1940s without being given an DRG designation in the 99 series.
#7, on the other hand, was designated 99 4602 and served into the 1960s on several East German narrow-gauge lines. It was taken out of service on the FShrhof - Altenkirchen and Altefahr-Putbus lines on 11 April 1965.
