Data from Alfred Bruce, The Steam Locomotive in America: Its Development in the 20th Century (New York: Bonanza Books, 1952), p. 275. See the description of the N&NW at [] (like no longer active) and [
] for the 2's image.. (Many thanks to Chris Hohl for his 22 September 2017 email reporting unlikely boiler pressure values for 177 entries. A Locobase macro caused the error .) Schenectady order number S-327 works number was 38876 in October 1905.
The builder's photograph shows a typical moderate-size short-line 4-4-0 locomotive. Although this engine was purchased for the N&NW, that Iowa railroad was shortly to be absorbed by the interurban-minded Fort Dodge, Des Moines & Southern. There being no place for steam, the N&NW's four locomotives were sent off to different homes.
Of the many competent compilers of locomotive rosters supplied through Allen Stanley's Rail Data Exchange, however, none has been able to reconstruct the #2's later employment with any certainty. Gene Connelly's Alco list suggested "Canadian Government Railways??".
