Diagrammes des machines SACM construites a GRAFENSTADEN (October 2007). SACM supplied the 50 engines in 1930-1931 (twenty of the class had works numbers 5611-5630), Cail added 20 in 1932.
Tall side tanks, five axles, hemispherical smokebox door, two long "bread loaf" domes (one steam, one sand), Belpaire firebox, curved-roof cab, boat-tail bunker combined to give the impression of stolid motivation. Suitable then for the role of hump engine or even short-haul freight transfer locomotive.
