Mullheim-Badenweiler 0-4-0 Locomotives in Germany

Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 21067)

Data from "2/2 gek. Tender-Locomotive fur 1 m Spurweite Spremberger Localbahn", (Tegel bei Berlin, 1878), p. 38. See also "Spremberg'" in Wikipedia at [], last accessed 7 August 2022. Works numbers were 4474-4476 in July 1898.

This trio of small tanks wasted little metal in presenting a very compact profile. They opened the 7.57 km (4.7 mile) Lokalbahn in 1898, which took passengers from the standard-gauge railway station in Mullheim and climbed 170 metres (558 feet) to reach Badenweiler's spas. (Mullheim lies east of Mulhouse and near the Swiss border.)

The 1 remained on the Mullheim-Badenweiler until 1957. 2 left the M-B in 1920 to run on the Oberrheinische Eisenbahn-Gesellschaft. 3 had the shortest career on the M-B as it was placed in service for the Kraftwerk Mannheim in 1914.
