Miramas a Port-de-Bouc 0-6-0 Locomotives in France
Class Details by Steve Llanso of Sweat House Media
Class unknown (Locobase 9150)
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.
This component of the Chemins de Fer d l'Interet Local des Bouches-du-Rhone network bought these two locomotives for their pulling power. On a 1 1/2% grade, they were credited with pulling 140 tonnes at 30 km/h (18 1/2 mph).
The railway itself didn't perform quite as lustily. Sampite shows that from 1881 to 1885,t he costs of running the 25-km line remained about the same. In that same period, however, revenue dropped 25% with the result that the line barely broke even in 1885.
