Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 31, p. 28. See also George W Hilton, American Narrow-Gauge Railroads (Stanford, CA: Stanford University Press, 1990), pp. 413-414. (Thanks to Chris Hohl for his 2 December 2022 email reporting the correct values for the water and fuel capacities.) Works number was 31692 in September 1907.
George Hilton wrote that the WW&F Railroad's predecessor Wiscasset & Quebec chose the 2-foot gauge in the hopes of linking up with the Kennebec Central and/or a three-rail (2 foot and standard gauge) link at Weeks Mills. Grading and construction proceeded rapidly in 1894 with the 28 miles to Weeks Mills opening in March 1895 and an additional 15.5 miles to Albion in November.
Neither of the connections panned out, Hilton adds, "and the line managed to be only a minor local carrier inland from Wiscasset.' The WW&F Railroad succeeded the W&Q, which went into foreclosure in 1900. Its bankuruptcy in 1906 led to reorganization as the WW&F Railway. By 1916, this small Maine railroad ran in the Sheepscott Valley from Wiscasset to Albion in service that included a "daily passenger-and-milk run" over the 43.5 miles (70 km). In that same year, its net earnings were recorded as $17.
Although managing to remain "barely profitable", traffic losses and a 1931 roundhouse fire hastened the end, which came in 1933.
