Construction history

The machines were built by Maschinenfabrik Esslingen (Emil Kessler), Charbonnier et Cie. (successors to the business of François Cavé), and Nord's works at La Chapelle in 1856–1857.[1] The locomotives were 0-4-6T Engerth locomotives for mixed traffic. The Stephenson valve gear and the cylinders were on the inside of the locomotive frame. The tender contained 4.5–5.5 m3 (159–194 cu ft) of water and 1,500–1,600 kg (3,310–3,530 lb) of coal.

Twelve machines were rebuilt as 0-4-2 tender locomotives between 1873 and 1878 at Nord (La Chapelle).
