Chilean State 2-6-0 Locomotives in Chile


Class Details by Steve Llanso of Sweat House Media

Class 291 (Locobase 12718)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 27, p. 125. Works number was 25022 in January 1905.


Class 39 (Locobase 11939)

Data from "New Locomotive Equipment," The Railway Age, Vol (24 August 1900), p 157 and "Locomotive Building", Railroad Gazette, Volume XXXII, No 34 (24 August 1900), p. 72. Works numbers were 5653-5654 in November 1900.

W R Grace ordered these two Moguls for the FC del Estado de Chile's broad-gauge lines.


Class 467 (Locobase 11417)

Data from "Locomotive Building," The Railroad Gazette, Vol XLII, No 22 (31 May 1907), p 758. See also Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 30, p. 272. (Thanks to Pablo Moraga for his 30 January 2016 email correcting Locobase's mistake in wheel arrangement identification.), Works numbers were 31735-31736, 31737-31744, 31804-31806, 31818-31821 in September 1907 and 31845, 31895, 32019 in October 1907.


Class 50 (Locobase 10756)

Data from Charles King, "The Chilian [sic] State Railways," The Railway Magazine (March 1908), pp. 209-214; see also the introductory article in the same journal at February 1908, pp.143-150 . First date was an estimate until Pablo Moraga emailed Locobase on 27 April 2022 revealing the road numbers and the correct date. Muchas gracias.) Works numbers were 5665-5666 in 1905.

The CSR expended a good deal of effort on reducing the spare-part count by ensuring that different classes used many of the same components. For example, this broad-gauge shunting tank used the same pony trucks, cylinders, motion, drivers, and axle-boxes as did the metre-gauge 2-6-2T shown in Locobase 10755. Its ambit was the CSR yards in Santiago and Valparaiso.
