Anglo-Chilean Nitrate 2-6-2 Locomotives in Chile
Class Details by Steve Llanso of Sweat House Media
Class 13 (Locobase 21000)
Data from "Anglo-Chilian [sic] Nitrate & Railway Type 2-6-2", Locomotives Constructed by Kitson & Co. Limited (Leeds, UK: n.d); and Robert Stirling, "The Tocapilla Railway" (Paper 3198), Minutes of Proceedings of the Institution of Civil Engineers, Volume 142 (3 April 1900) pp. 89-102 in Table II, p. 93.

Locobase treats all ten (more on that in a moment) of these engines as a single Kitson design for the ACN&RC. He bases his tentative compilation on (Road #14 was ordered twice, the second being a replacement for the first, which was lost at sea.). A guiding requirement for the Prairie tanks seems to have been a maximum 8 3/4 long ton axle loading.
