Saint Germain 0-6-0 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class Antee (Locobase 11349)

Data from L Chatelier, E Flachat, J Petiet, and C Polonceau, Guide du Mecanicien Constructeur et Conducteur de Machines Locomotives (Paris: Chez Paul Dupont, 1851), pp. 374 and tables on 376-387.

Actually built for the La Pecq-Saint Germain, this locomotive was credited with a tonnage rating of 15-16 voitures (passenger coaches) amounting to 96 tonnes up a grade steep enough to equate to 560 tonnes on the level. The design had its dome placed well forward just behind the stack, wood lagging on the boiler and cylinders,
