S.G. CF Economiques - Blayais et La Gironde 0-6-0 Locomotives in France
Class Details by Steve Llanso of Sweat House Media
Class unknown (Locobase 9173)
Data from A. Sampite, Les Chemins de Fer a Faible Trafic en France (Paris: Baudry et Cie, 1888), p. 49. See also [

The Societe Generale des Chemins de Fer Economiques was created in the Department in 1880 to encompass a great network of lines throughout Landes and La Gironde. Four lines fell under the SG heading:
Lesparre a Saint-Symphonien 139 km / 86 miles
St. Andre-de-Cubzac a St Ciers-la-Lande 50 km / 31 miles
Lacanau a Bordeaux 44 km / 27 miles
Hostens a Beautiran 34 km / 21 miles
The first segment - Ares a Facture - opened 7 January 1883.
These tank engines were based on studies by the Nord's Central Materials Engineer M Banderali. An observer's conclusion that they are smaller than many of the other that rand on Reseau d'Interet Local lines is confirmed by Sampite's comment that they were "excellent, but perhaps a little underpowered (faibles) for higher traffic loads." (Locobase's free translation). The design may have been limited by the 25-kg/meter (50-lb/yard) rail; each 8-meter (26 1/4 ft) section was laid on 8 sleepers. A maximum speed of 50 km/h (31 mph) was authorized, but in practice speeds didn't exceed 30 km/h (19 1/2 mph).
