Strassburger Strassenbahn 0-4-0 Locomotives in Germany

Class Details by Steve Llanso of Sweat House Media

Class 01 (Locobase 15617)

Data from diagram No 05, Societe Alsacienne de Construction Mecaniques from SACM locomotive book supplied by Dany Machi up at [] as

Diagrammes des machines SACM construites a GRAFENSTADEN (October 2007). Works numbers were 3824-3825 in 1887.

The French-language diagram described this German railway (won in the 1870 Franco-Prussian War) Elsass-Lothringen subsidiary as the "Tramway de Strasbourg". The line began as a horse tramway in 1877 and, presumably, these small tanks were the first steam engines. They were not "dummies" (i.e., they looked like small locomotives) but had a large window in the rear wall of the cab to permit bi-directional operation.
