Tramways de Loir-et-Cher 0-6-0 Locomotives in France

Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 9429)

Data from G Humbert, Traite Complet des Chemins de Fer, Tome Troisieme (2nd Ed) (Paris: Ch Beranger, 1908), pp. 423-426.

See Locobase 9236 for a full discussion of tramways that focuses on the tramway de la Sarthe, which operated very similar vehicles to the one shown here.

Compared to the Sarthe tramway locomotives, these of the Loire-et-Cher had smaller boilers, grates and fireboxes, but put about 1,700 more kg on the rails. Humbert comments that with such small drivers, this design couldn't go much more than 25-30 km/h in the country and were in any case limited to 6-10 km/h in the city; average package-train speed was about 16-17 km/h. The trailing load averaged 35 tonnes.
