Ruegener Kleinbahn Articulated Locomotives in Germany
Class Details by Steve Llanso of Sweat House Media
Class 31 / 99. 4521 (Locobase 6531)
Data from Christian Lindecke's [
] (accessed 26 May 2005), supplemented and corrected by the Rugen website []
(accessed 29 December 2006) . Lindecke tells us that the 96.8 km (60.1 sm) of Rugen lines were built between 1896-1899 to link Bergen and Altenkirchen and Gohren and Altefahr.
In order these pocket Mallets arrived from Vulkan's Stettin.
Road # Year Works number
31 1902 2010
32 1902 2013
33 1905 2172
34 1908 2451
For some reason, the fifth vierkuppler came from Hanomag in 1911 (works number 6227).
All of this class continued in operation until 1965-1966.
