Chemins de fer de l'Herault 0-8-0 Locomotives in France
Class Details by Steve Llanso of Sweat House Media
Class 51 (Locobase 9161)
Data from A. Sampite, Les Chemins de Fer a Faible Trafic en France (Paris: Baudry et Cie, 1888), p. 49. See also [
] for a history of these Freycinet Plan railways and Wikipedia [] (accessed 2 February 2008).
The Reseau d'Interet Local CF de l'HTrault was a network of secondary lines along the Gulf of Lyon in Southeast France. Sampite provides a summary of all the locomotives then in service on any of the lines and Wikipedia fills in the blanks. Note that none of the series of locomotives (Locobase 9159-9164) had either boiler pressure or grate area. The boiler pressure is an estimate.
One advantage of 4 axles is the ability to spread out the adhesive weight, as was done in the case of this quartet. They served l'Herault until 1940.
