Ruhr-Lippe Kleinbahn Articulated Locomotives in Germany

Class Details by Steve Llanso of Sweat House Media

Class 10 (Locobase 8042)

Data from Roland's Eisenbahnseite ([], accessed 27 December 2006), the Ruhr-Lippe Kleinbahn site ([]) and the [] . The RLK took delivery of these five small Mallets just in time to have most of them impressed by the German Heeresfeldbahn. After World War One, 10-12 (works numbers 1646-1648) came under French control (as part of reparations) and were redesignated HK 114-116. 14 served only a short time on the RLK, moving on to the Sndharzer Eisenbahn (SHE) as their 1st 55. Like the 10-12, 14 (1792) wound up in French custody.

13 (1791) remained in German hands and saw out a long career with the RLK, being retired in 1952.
