Chemins de Fer du Medoc 0-6-0 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 9167)

Data from A. Sampite, Les Chemins de Fer a Faible Trafic en France (Paris: Baudry et Cie, 1888), p. 49. See also [link] for a history of these Freycinet Plan railways

Locobases 9167-9171 present the data for 5 different locomotive designs that operated on the CF du Medoc. Of the two lines that made up this Reseau in southwestern France, the Bordeaux au Verdon was 10 times longer than the Margaux a Castelnau; the B au V covered 101 km (62 miles) and the M a C 10 km (6.2 miles). And Sampite notes that the larger line is a Ligne d'interet general that has the character of a ligne d'interet local, while the Margaux branch was established in 1880 under an 1865 law.

Only 10 locomotives moved traffic on these lines. Of those, 4 were built to the same design at Fives-Lille 13 years apart. This is the earlier pair; the only difference in the specs is slightly lower weights.


Class unknown (Locobase 9168)

Data from A. Sampite, Les Chemins de Fer a Faible Trafic en France (Paris: Baudry et Cie, 1888), p. 49. See also [link] for a history of these Freycinet Plan railways

Locobases 9167-9171 present the data for 5 different locomotive designs that operated on the CF du Medoc.

Locobase 9167 notes that 4 were built to the same design at Fives-Lille 13 years apart. This is the later pair, which weighed a little more but were otherwise identical to the earlier pair..
