État 40-001 to 40-143 comprised a series of 0-8-0 Tank locomotives initially utilized by the Chemins de Fer de l'État and subsequently by SNCF, which assigned them new numbers ranging from 3-040.TA.1 to 3-040.TA.143.
Design
The 40-000 series employed a two-cylinder simple expansion system, incorporated a Crampton-style firebox, and used Walschaerts valve gear. The connecting rod was linked to the third axle; the boiler was equipped with a steam dome positioned on the first ring and a sandbox located on the second. Water tanks situated alongside the firebox featured inclined fronts, enhancing both operator visibility and track safety. Variations included locomotives with either open or enclosed cabs.
Conceived as replacements for 0-6-0 shunting engines with a traction capacity of 40 tons, these 0-8-0 locomotives provided a tractive effort of 60 tons. Their development commenced in 1913 within the Chemins de Fer de l'État’s research division to meet operational demands.
Construction
Between 1914 and 1922, a total of 143 units were produced, although manufacturing was interrupted by World War I. The initial batch of eighteen locomotives (40-001 to 40-018) entered service in 1914. Construction halted during the war, and two units from this group, 40-019 and 40-020, were seized by German forces, only returning in 1919 and 1922 respectively. Production restarted in 1920, concluding the series by 1922. Most locomotives were built by French engineering companies, with six constructed at the former Ouest workshops located in Sotteville, Rouen. Comparable models were also manufactured for industrial use within France.

Service
These locomotives operated out of numerous depots throughout France such as Paris-Vaugirard, Montrouge, Batignoles, Sotteville (Rouen), Le Havre, Dieppe, Trappes, Chartres, Caen, Cherbourg, St-Brieuc, Brest, Nantes, Rennes, and La Rochelle, as well as on industrial railways and port facilities. After the establishment of the SNCF, they were reclassified from their original État numbering to the SNCF system as units numbered from 3-040.TA.1 through to 3-040.TA.143.
During World War II, German forces requisitioned fifty-two locomotives; many were modified with enclosed cabs during this period. Twenty-five never returned after the war and were subsequently dismantled. In the decades following the war (1950s–1960s), twelve locomotives found new roles with industrial operators.
Preservation
Two locomotives from this series have been preserved:
- Locomotive number 40-137 (ANF serial no.143 of 1922), later known as SNCF 3-040.TA.137, was among those taken to Germany and is currently exhibited at the Musée vivant du chemin de fer in Longueville, Seine-et-Marne. It holds the status of a Monument historique.
- Locomotive number 40-141 (Sotteville serial no.64 of 1922), subsequently SNCF number 3-040.TA.141.
