Class Details by Steve Llanso of Sweat House Media
Class Corse (Locobase 3794)
Data from UG Type 175, Societe Alsacienne de Construction Mecanique of SACM Locomotive book supplied by Dany Machi up at [
] as
Diagrammes des machines SACM construites a GRAFENSTADEN (October 2007). Works numbers were 1951-1954, 1650-1652, and 7653-7655.
The first of these engines were among the first Mallets to be built. The source shows 22 having been built from 1892 to 1932.
