The SociTtT GTnTral des Chemins de Fer Economiques was a network of metre-gauge railways of "local interest" to supplement the mainline, standard gauge system. The first impetus for "secondary" railways came from an 1865 act, but it was the 1880 Law that inspired construction of the majority of such lines.

See the highly estimable FACS-UNECTO site for tables on all of France's secondary railways. In particular, the Gray-Haute-Saone region shown at [] (accessed 10 Feb 2006) was a web of metre-gauge lines for which the locomotive displayed by SACM possibly was intended. On the other hand, the website of the Baie-Somme museum railway -- [] -- describes several lines that could have operated this radial tank.

The trailing axle was fitted with Roy's radial boxes and the assembly could negotiate curves as tight as 100 m (328 ft) in radius. It was credited with a straight-line speed of 35 km/h (21 mph) and could scale 2 1/2% grades.

Locobase 7429 describes the basic 0-6-2T design for the secondary rail system in France as presented at the 1889 Paris Exposition. The current example clearly derives from that earlier engine, but had a larger grate and firebox and one less firetube. Humbert noted that it was capable of 40/kmh on easy grades and could tackle ascents of 2 1/2 to 3%.
