Standard Consolidation built for the US Army's Transportation Corps just before World War I. Not as powerful as many similar locomotives on private roads and fitted with piston valves that measured 10" (254 mm ) in diameter. . Most operated in France and many remained in that country after World War One.

Wikipedia in French helpfully offers a list of how these locomotives were distributed during and after the war, identifying subgroups as "Pershing" (delivered during the war), "Felton" (ordered or delivered after the Armistice of 11 November 1918), and "Slade" (ordered on 10 January 1919) to flesh out the depleted stocks of the major railroads

296 Pershing, 119 Felton and 40 Slade (410 Pershing, 45 Alco) to la Compagnie des chemins de fer de l'+tat--the Pershings were numbered 140.1101 to 140.1510. Note: 45 of these were Brooks-built engines with more cylinder volume; see Locobase 432

106 Pershing, 32 Felton et 15 Slade (153 Pershing) to la Compagnie des chemins de fer du Midi , where they took numbers 4201-4353

132 Pershing, 80 Felton et 30 Slade (242 Pershing) to la Compagnie des chemins de fer du Nord, which numbered them 4.1301-4.1542

388 Pershing, 127 Felton et 63 Slade (549 Pershing, 29 Alco) to la Compagnie du chemin de fer Paris-Lyon-MTditerranTe. The Pershings took 501 a 969. See Locobase 15481 for the Alcos.

156 Pershing, 62 Felton et 27 Slade (169 Pershing, 76 Alco) to la Compagnie du chemin de fer de Paris a OrlTans, the Pershings taking 7101 a 7349.

And 7001 a 7076 pour les ALCo

61 Pershing et 22 Slade (83 Pershing) to le RTseau ferroviaire d'Alsace-Lorraine o+ elles furent immatriculTes : G14 n¬ 5701-5761, G14 n¬ 5801-5822

160 Pershing et 50 Felton (210 Pershing) to la Compagnie des chemins de fer de l'Est and placed in class sTrie 12s n¬ 40.101 a 40.310.

Upon the formation of the SNCF in 1937, they were grouped under the class 140C (later 140G). According to "Des Surnoms Pour La Vapeur," Rail Magazine, No 7 (November 1977), p.13, this design attracted several nicknames including Americaines, TP, Pershing, and Boiled-Beef. TP stood for Travaux Publics (Public Works).

After the war, a few others moved onto private railroads such as the Atlantic Coast Line (L-4).
