Anglo-Chilean Nitrate 0-4-0 Locomotives in Chile


Class Details by Steve Llanso of Sweat House Media

Class 6 (Locobase 21019)

Data from 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. See also Martin Coombs, Chilean steam locomotive list, Part 2, Standard, 4' 6", 4' 2" and 3' 6" locos, 2018, p. 89 downloaded from [link], last accessed 8 April 2022. Works numbers were 1107 in 1888 and 1126 in 1889.

These were small shunters.
