040 TA Ouest
Encyclopedia
The 040 TA was an 0-8-0
tank engine
of the Chemins de Fer de l'État.
. These were designed to replace the 030 0-6-0
shunting engines. The 0-6-0 engines possessed a traction force of 40 tons, while the 0-8-0
were designed to have a traction force of 60 tons. It was in 1913 that the research department of the Chemins de Fer de l'État began to study the question of a replacement. The first 18 engines, numbered 40-001 to 40-018, were put into service in 1914. The war prevented the construction of the rest of the series, and just two engines, 40-019 and 40-019, were built. Construction resumed in 1920 and the full series of 143 engines was put into service by 1922. The engines were assigned to the depots of Paris-Vaugirard, Montrouge, Batignoles, Sotteville (Rouen), Le Havre
, Dieppe, Trappes, Chartres, Caen, Cherbourg, St-Brieuc, Brest, Nantes
, Rennes
and La Rochelle as well as industrial railways and harbours. When the SNCF
was formed, the series was renumbered 040 TA 1 to 040 TA 143. There are two examples of this class which have survived into preservation. They are 040 TA 137 & 141.
A replacement for the 040 was difficult to design as diesel transmission could not cope with slow and long starts.

Design
The 040 were of simple expansion with two cylinders and possessed a Crampton firebox and Walschaërts type valve gear. There were variants in cabs and several open cabs, others, closed. The water tanks on each side of the firebox possessed a sloping front and gave the driver additional vision and permitted him to see if workmen were on the track in front of the engine.A replacement for the 040 was difficult to design as diesel transmission could not cope with slow and long starts.
