0-4-4 Steam Locomotives in Chile

Santiago & Valparaiso


Class Details by Steve Llanso of Sweat House Media

Class Placillla/Tipo 11bis (Locobase 21349)

Data from Chilean State Railways (EFE) diagram book, 11bis, supplied in August 2025 by Allen Stanley from his extensive Rail Data Exchange collection. See also Martin Coombs, Chilean steam locomotive lists, Part 1, Broad gauge locos (v2.64, March 2026), p. at [].

Martin Coombs searched the records and came up with this inspection engine's likely origins:"Probably the ex-FC Ilo a Moquegua [a Peruvian railway] `passenger pony' [delivered by Rogers in 1872] named `EL HUANACO'. Rebuilt 1884 as an inspection saloon but in fact may well have been like that from new." [See Coombs's detailed discussion of Placilla's origins on his pages 34-25, especially note the illustrations.].

Although the arrangement suggests an 0-4-0T leading a sizable structure mounted over an extended frame supported by a bogie truck, Coombs discovered a counter description (p. 24) in a Rogers diagram: "Interestingly the end elevations are labelled `Front view' meaning the saloon end, and `Back view' meaning the chimney end - very logical for an inspection saloon."

Page 59 shows a later version of the inspection body work, which still included the engineer's footplate, but now offered two doors. Locobase wonders if the diminuitive 60 also served as a delivery wagon of sorts.

Still listed on the EFE's roster in 1928, the 60 probably was withdrawn by 1930.


Class Porvenir/Tipo 4 (Locobase 21340)

Data from Chilean State Railways (EFE) diagram book, 53, supplied in August 2025 by Allen Stanley from his extensive Rail Data Exchange collection. See also Martin Coombs, Chilean steam locomotive lists, Part 1, Broad gauge locos (v2.64, March 2026), p. at [].

This engine arrived as another Black, Hawthorn 0-4-2 in 1856. Years later the shops converted the Porvenir into a shunter by replacing the single rear carrying axle with a bogie and eliminating the tender.

Coombs found the Porvenir in a 1928 accounting, which described the locomotive as "obsolete or knocked-down."
