They were built to handle the increasing output of the steel industry in the Lorraine area. OriginsThe locomotives were developments of the prototypes 4001 et 4002 which had been built for the Est by Société alsacienne de constructions mécaniques (SACM) in 1902. They were built in three batches, with the first two built by the Est's Épernay Works, and the third built by the various private contractors:
DescriptionThe Consolidations were four-cylinder compound locomotives with Walschaerts valve gear. They were provided with a Belpaire firebox, Adams piston valves, and an Est-type horizontal regulator. TendersOriginally these were two-axle tenders which held {{convert|13000|l}} of water and {{convert|5|t}} of coal; they had a gross weight in working order of {{convert|33.5|t}}. The 4091 to 4175 were equipped from new with three-axle tenders with a capacity of {{convert|22000|l}} of water and {{convert|8|t}} of coal; weight in working order was {{convert|50.6|t}}. These tenders were gradually assigned to the earlier locomotives. Usage and servicesThey became the Est's standard heavy 2-8-0 freight locomotive and were designed to haul heavy trains. They were allocated to many of the depots in Eastern France, like Nancy, Bar-le-Duc, Reims, Troyes, Saint-Dizier, Vesoul, Belfort, Châlons, and others. On an easy grade, the superheated locomotives were able to move a {{convert|1200|to|1500|t|sigfig=3|adj=on}} train at {{convert|40|to|45|km/h|mph|abbr=on}}, with peaks of {{convert|50|km/h|mph|0|abbr=on}} possible. They could pull a {{convert|340|t}} train at {{convert|20|km/h|mph|0|abbr=on}} up a 20.0 to 22.5 per mille (2.00 to 2.25 percent / 1 in 50 to 1 in 44.4) grade. All were still in service at nationalisation, and they were renumbered by the SNCF as 1-140.A.3 to 1-140.A.175. Between 1932 and 1946 several were rebuilt with larger steam passages, a 6-jet exhaust system and smoke deflectors. These "Chapelonised" locomotives were reclassified from A to C by the SNCF.{{sfn|Baxter|2001|p=64}} They became the Est's standard heavy 2-8-0 freight locomotive Being a standard Est locomotive class, they stayed in service until they were replaced by the SNCF 141R class locomotives during the period 1948–1951. All were withdrawn by 1954 and none were preserved.{{sfn|Baxter|2001|p=65}} Characteristics
