Class 1, 21 (Locobase 12013)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 17, p. 181 and Volume 19, p. 91. See also See also Martin Coombs, "Chilean Steam Locomotive List - Parte 4", Sub-metric gauge locos, pp. 220-222, downloaded from [], last accessed 8 April 2022 .p. 67.. Works numbers were 12398-12399 in January 1892,13995-13996 in April 1894, 14111-14115 in October, and 14236-14238 in March 1895.

This British-owned railway didn't balk at buying a pair of double-ender tanks for this key railway in Chile's northern province of Tarapaca, then repeating the orders over the next three years. Local dealer Balfour, Williamson bought five more originally ordered by Hemenway, Browne. These too went to the ASN as did 3 more in 1895. Three more from 1913 appear in Locobase 13996.

Martin Coombs states that most photographs of this class show the engines trailing tenders (2-4-2ST+4). A regular tank lay on the two separate axles over which a shallow tray carried additional coal. The front sand dome consisted of a dry extension of the saddle tank to fit around the stack.

Class 21 (Locobase 13996)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 44, p. 198. Works numbers were 39067-39069 in January 1913.

Nineteen years after the ASN had bought its double-ender saddle tanks from Baldwin through broker Balfour Williamson (Locobase 12013), it took delivery of three more that were essentially identical except for having a higher boiler pressure and slightly greater weights.
