Germain y Sierra, contractors 2-6-0 Locomotives in Chile


Class Details by Steve Llanso of Sweat House Media

Class 3 (Locobase 20881)

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, "2-6-0 d/w 38", cyls. 13"x18", built by Vulcan Iron Works in 1910", Chilean steam locomotives lists, Part 3 Metre-Gauge locos (October 2020), p. 49 -available at [], last accessed 25 April 2021. Vulcan Iron Works numbers were 2296-2297 in May 1914 and 2307-2308 in July 1914.

Unfortunately, the Vulcan specification did not include heating surface areas or grate area. Locobase estimated the grate area, but is willing to be corrected.

Two VIW class J-T Moguls supported the Chilean contractors and later served the EFE (Chilean State Railway). Their spec originally called for operations on a 4-foot (1,219 mm) gauge, but an inked correction reduced the gauge to 1,000 mm.


Class Louis Serrano (Locobase 20880)

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 64 (1st & only batch) 2-6-0 d/w 46", cyls ...built by Vulcan Iron Works in 1914", Chilean steam locomotives lists, Part 1 Broad-Gauge locos (October 2020), p. 142 -available at [], last accessed 25 April 2021. Vulcan Iron Works numbers were 2296-2297 in May 1914 and 2307-2308 in July 1914.

Unfortunately, the Vulcan specification did not include heating surface areas or grate area. Locobase estimated the grate area, but is willing to be corrected.

Coombs reported that the first two of these Vulcan clsss J-T Mogul locomotives had cylinders with 20" (508 mm) strokes, but the Vulcan specifications shows all four with the 24" stroke shown above. Names in order were Louis Serrano, Carlos Symmes, Gabriel Quiros, and Alejandro Guzman".

Coombs's research shows that all four remained in service, latterly with the EFE (Chilean State Railway) as late as 1957. At least one carried until 1968.
