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; corrected and supplemented by "140 n° ALVF 36 à 70, puis K 1 à 35 du PLM" in the Traction-Vapeur section of the WikiPLM at [],_puis_K_1_%C3%A0_35_du_PLM, last accessed 2 September 2023. See also "140-101 à 370 État ou 140 C SNCF" in Wikipedia at [], last accessed 2 September 2023; and Locobase 6375 (for the Etats).Thanks to Piotr Staszewski for his 1 September 2023 email correcting the builder and supplying the works numbers.) Works numbers were 3235-3244 in 1919, 32-45-3269 in 1920.
The ALVF was the French Artillery arm of the French Army and they were the original purchasers of this set of British-built Consolidations. Like the later Pershings, these were built to French specifications that included a Zara truck. They had larger-diameter boilers than most of the French Consolidations, but used the Belpaire firebox.
In 1924, the PLM took them over and placed them in their own 140 K class.
