Data from SACM diagram UG Type 170 from Elsassische Maschinenbau AG from locomotive book supplied by Dany Machi at [] as
Diagrammes des machines SACM construites a GRAFENSTADEN (October 2007). Additional information from Phil Dambly, "OnziFme pTriode, 1940-1946 - Reprise du + Nord Belge + (suite)" posted 24 November 2010 at Rixke Rail's Archives ([], last accessed 21 January 2013).
Locobase takes at his word Dambly's statement that these compound Consolidations were "absolutely identical" to the Nord 140As that began appearing in 1921 (Locobase 14873) and repeats the dimensions from the earlier entry. Dambly reports that these engines developed 2,000 horsepower and could pull 1,600 tonnes (1,764 short tons) up a 0.5% grade. They also would be pressed into service to haul heavy passenger trains.
NB: Tube and flue diameters are water side dimensions as used in Anglo-American practice. The fireside dimensions were as follows: 84 tubes had 65 mm (2.56"), 6 had 60 mm (2.36"); the larger flues measured 125 mm (4.9 in) on the fire side.
