Piston valves measured 10" (254 mm ) in diameter. See Locobase 431 for the description of this very large class built by Baldwin to a single design for service in France.


Class 140-101 / 140C (Locobase 6074)

Data from US Military Railway Service Equipment Data Book for French Locomotives supplied by Allen Stanley in March 2004 from his extensive Rail Data Exchange. Information also from Roland Arzul's [link]

Plus 19 tubes of 1.99" diameter. The first batch of these locomotives was supplied by Schneider in 1913. But the impact of the war on French industry meant farming out the rest of production to North British Locomotive and Nasmyth Wilson. Whatever the builder, the result was a sturdy machine with additional asset of a light axle loading. Some of this class carried on until the end of steam in 1975.

The website -- [link]-- of the museum that has one of the survivors comments:

"Leur robustesse, leur simplicity, leur faible covt d'utilisation et leur aptitude a rouler sur toutes les lignes meme les moins bien entretenues les fit tres apprecier des compagnies de chemin de fer puis de la SNCF. Ce sont egalement ces qualites qui leur value d'avoir une carrire particulirement longue puisque les dernieres machines en service en 1975 avaient 62 ans de bons et loyaux services."

Boiler capacity was 2,680 US gal.

An FAQ for the CFTV museum railroad asks how much water and coal does 140C314 consume in the 23-km run from Saint-Quentin to Origny-Sainte-Benoete?

Between 2,112 and 2,640 US gal (8 to 10 cubic meters) or water and 2.2 short tons (2 metric tons) of coal.


Class 151/140.501 (Locobase 432)

Data from "Locomotives for French Railways," Railway Mechanical Engineer, Volume 92, No 3 (March 1918), pp. 136-139 Works numbers were Schenectady 59136-59225, Brooks 59226-59285 all in 1918.

These were duplicates of the Midi engines that had lower builders' numbers and were produced a year earlier (Locobase 15481). Compared to the Baldwin Pershings built beginning a year earlier (Locobase 431), this design had a much more European look with a high-pitched boiler and smaller cab. Piston valves measure 10 1/4" (160 mm) in diameter.

The RME report says that 100 were delivered to the Etat and 40 to the Midi, but Connelly's Alco production list shows the 150 builder's numbers presented immediately above as well as a separate set for the Midi engines. The last 50, although numbered serially with the 100 described in the article, were ordered later in the year.

"Des Surnoms Pour La Vapeur," Rail Magazine, No 7 (November 1977), p.13, says that the wagon-top boiler led to their being nicknamed Bossues ("battered", possibly in the meaning of sloped) and "Dos de Chameau" (camel back). Locobase thinks either nickname would have better fitted a Belpaire-firebox design.

They were later designated 140H by the SNCF.
