Mullheim-Badenweiler Articulated Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 21068)

Data from "2x2/2 gek. Tender-Locomotive fur 1 m Spurweite Spremberger Localbahn", (Tegel bei Berlin, 1878), p. 39. See also "Mnllheim-Badenweiler Eisenbahn'" in Wikipedia at [], last accessed 7 August 2022. Works numbers were 4644 in May 1898.

The only Mallet to operate on the Mullheim-Badenweiler, the railway's electrification in 1914 led to its sale in 1914 to the Lubben-Cottbuser Kreisbahn as their 7.
