Locobase 11268 described the class derived from PLM's Bourbonnaise 6-coupled; it entered service on the Etat in 1874. This batch was based on a Midi class, although it was "noticeably less powerful". The dome was positioned well forward (as in the 3139 class); it contained not only the safety-valve assembly, but also the swan's neck regulator.

As Demoulin noted, these six-coupled engines took their lines from the widely distributed Bourbonnaise class of the PLM (Locobase 599). The boilers had a bit less heating surface area, the grate a skosh more. They had a typical Etat look, he says, in placing a large dome with internal safety valve well forward on the boiler and using balanced valves.
See Locobase 11269 for the variant that rolled on 1,500-mm diameter drivers.
Data from Maurice Demoulin, Traite Pratique de la Machine Locomotive (Paris: Libraire Polytechnique, Baudry et Cie, 1898), pp. 125-126. The first 20 engines--works numbers 2041-2060 in 1880-came from S.A. des anciens Etablissements Cail and Batignolles delivered the last 50-works numbers were 1020-1079 in 1882-1883.
Produced in the same mold as the 3069s (Locobase 11269) that were themselves based on the Midi's six-coupled engine, this later batch had larger cylinders and a slightly larger grate.
Later the Etat transformed three of the Cail and 21 of the Batignolles locomotives to 2-6-0 Mogul tanks by adding a leading Bissel truck.
Data from SACM diagram Loco 40 Tend 32 from Societe Alsacienne de Constructions Mecaniques from locomotive book supplied by Dany Machi up at [] as
Diagrammes des machines SACM construites a GRAFENSTADEN (October 2007); and "Locomotives", Type 79, . SACM works numbers were 580-587 in 1871 and 2803-2806 in 1878; Ernest Gouin et Cie works numbers were 800-803 in 1873; Schneider et Cie Type 79 works numbers were 1706-1713 in 1876.
Tube diameter is the interior measurement. The diagram shows a small cab with two windows per side behind a long boiler with the large steam dome just behind the stack and over the first axle. Schneider's data differed very little from those delclared by SACM'.
These were among the very first engines delivered to La Vendee, which opened in 1865. By the time the railway system was taken over by the Etat in 1878, its route mileage came to 495 km (308 miles).
The Etat later rebuilt the class as 2-6-0s and serially assigned 3601-3606 as road numbers.
Data from SACM diagram Nr. 65 from Societe Alsacienne de Constructions Mecaniques from locomotive book supplied by Dany Machi up at [] as
Diagrammes des machines SACM construites a GRAFENSTADEN (October 2007).
Tube diameter is the interior measurement. The relatively tall drivers mark this six-coupled as a mixed-traffic locomotive (and as its designation "Mixte" implies).
