Data from "Double End Tank Locomotive for the Kiushiu Railway, Japan," The Railroad Gazette, Volume XLI [41], No 20 (18 November 1906), p. 431. See also Catalogue 10036-Locomotives for Export (New York City: American Locomotive Company, 1910), pp. 86-87. Works numbers were 41290-41313 in August 1906.
RG's brief note reported that they were intended "for heavy passenger and fast freight service and have a large tank capacity for their size."
