Data from M Grille, Les Chemins de Fer de L'Exposition de Chicago (Paris: E Bernard et Cie, 1894), pp. 24-27. Works number was 4047 in 1893.
Out of the hundreds of six-coupled switchers ultimately procured by the C&NW, this was the only K-5. At the time, it was the only 0-6-0 with this combination of cylinder volume and wheel diameter. In 1896, the 140 was joined by the M-1 class, which evidently was the production variant and differed primarily in a boiler setting of 170 psi (11.72 bar). In the 1893 Columbian Exposition, the locomotive had neither a railroad nor a road number. Instead, it was described by Schenectady as an industrial switcher used in the builder's own yard. Sometime after Schenectady amalgamated with other builders to form the American Locomotive Company, it produced a data card for the engine and gave it C&NW road number 459. Locobase's research suggests the engine never actually bore that number. Its unique class ID didn't mean a short career. Instead, the 140 operated for more than 30 years before in being sold in May 1925.
