Class Details by Steve Llanso of Sweat House Media
Class Gonzalo Urrejola (Locobase 20878)
Data from "Vulcan Iron Works Germain y Sierra Order Data and Photos" supplied in April 2021 by Allen Stanley from his extensive Rail Data Exchange collection; and "Vulcan Iron Works negatives 1971.210" finding aid downloaded from the Hagley Museum website at [
], last accessed 25 April, 2021; and Martin Coombs, "Tipo 65 (1st & only batch), 0-4-2ST d/w 914mm 36", cyls. 305x406mm 12"x16", Chilean steam locomotives lists, Part 1 Broad Gauge locos (October 2020), p. 143 -available at [], last accessed 25 April 2021. Vulcan Iron WorksWorks numbers were 1885-1886 in April 1912 and 2182 in June 1913..
Unfortunately, the Vulcan specification did not include heating surface areas or grate area. Locobase estimated the grate area, but is willing to be corrected.
The G y S took delivery of the first two tanks--the second named Juan Castellon--were delivered to Valparaiso in April 1912 with Juan Luis Sanfuentes in 1913. When
