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 [] . (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 .) Works number was 38876 in October 1905.
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.
