Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 7430)

Data from Titre Exposition universelle internationale de 1889 a Paris. Rapports du jury internationale. Auteur - Volume France. Ministere du Commerce, de l'industrie. Picard, Alfred, ed. Volume Groupe VI - -Outillage et precedes des industries mecaniques. Electricite (5e partie) Classes 60 a 63. Rapport sur le materiel des chemins de fer. p. 304([] (accessed 1 September 2005).See also The FACS-UNECTO site at [] (accessed 11 February 2006) --

The FACS-UNECTO site shows us that this line was established a year before the 1889 Exposition at which this little tank was displayed. The Dordogne Region in the interior Southwest of France is named for the river that empties into the Bay of Biscay at Bordeaux. Within the Dordogne lies the Perigord, with its unofficial cultural capital Perigeux lying about 60 mi (ca 100 km) northeast of Bordeaux.

Ultimately the CFP consisted of several metre-gauge lines radiating from Perigeux:

PTrigueux - St-Yrieix-PO (83 km)

PTrigueux - St-Pardoux (52 km)

PTrigueux - Vergt (23 km)

Embranchement du Port de PTrigueux (1 km)

Except for the Perigeux-Vergt line (1899) and the dock railroad (1892), virtually the whole system was in use by the early 1890s. The system remained essentially intact until it was closed in 1949.

The Jury's report notes that this locomotive was deliberately built with a short wheelbase to allow it to negotiate tight curves.
