Data from SACM diagram UG Type 189 from Societe Alsacienne de Constructions Mecaniques from locomotive book supplied by Dany Machi up at [] as
Diagrammes des machines SACM construites a GRAFENSTADEN (October 2007). Works numbers were 7688-7697 IN 1933.
Locobase hasn't been able to resolve his question over this subclass's identity. It's clear from a comparison of the data in this entry with that of the Nord's 4.1201 class of Mikcado tanks (Locobase 2132). Yet SACM's diagram of its Type 189 clearly labels the ten engines as going to the "Franz.Norbahn". A
Superheater flue diameter is the exterior measurement. The Belpaire boiler had two sizes of tubes: 36 with 45 mm/50mm (inside/outside diameters), 65 Serve tubes with 65/70 mm.
