Unspecified 0-6-2 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class Vaugenray (Locobase 10724)

Data from [], last accessed 9 August 2009.

This relatively challenging railway alignment was served by the sextet of radial tanks delivered in 1885 (4), 1887 (1), and 1892 (1). They were named VAUGNERAY, MORNANT, CRAPONNE, RH+NE, LOIRE, and CROIX-ROUSSE and cost 42,000 Francs new. The class tackled the grade between Etoile d ' Alai (Francheville) and Craponne. They were rated at 47 tonness up a 2% grade (2 mm per metre) and around 250-m minimum curve radius at 40 km/h and 144 tonnes up the 2% without curves at 15 km/h.

RHONE and CROIX-ROUSSE were sold to CF de La Mure in 1900. At that time, LOIRE was renumbered 4.

The very last of these locomotives to leave service was MORNANT, which was withdrawn in 1930.


Class unknown (Locobase 9434)

Data from G Humbert, Traite des Chemins de Fer d'Interet Local (Paris: Ch Beranger, 1893) , p. 270-273. (Thanks to Wes Barris of steamlocomotive.com for his 13 June 2018 email noting a missing cylinder count.)

These very-narrow-gauge engines were designed for the agricultural lines built throughout France in the late 19th Century. A smaller Decauville four-coupled radial tank appears in Locobase 9433. The current entry portrays the larger stablemate that had an additional axle and larger boiler, but was otherwise very similar.
