Chilean State 0-6-0 Locomotives in Chile


Class Details by Steve Llanso of Sweat House Media

Class 457 (Locobase 21048)

Data from by Flickr photostream of "0-6-0 Locomotive for the Chilian [sic] State Railways", last accessed [link]. See also Martin Coombs, Chilean steam locomotive list, Part 1, Broad-gauge locos, 2018, p. 113 downloaded from [link], last accessed 8 April 2022. Works numbers 6658-6662 in February 1908.

This quintet of long-stroke six-coupleds may have not been fully satisfactory as all of them were listed as withdrawn in 1923. Perhaps their relatively small size for goods engines on the broad gauge proved telling.

A 1928 roster described them as "obsolete or knocked-down [dismantled?]. 461 had


Class Tipo-b (Locobase 21021)

Data from "Locomotora Tipo-b" from scans supplied by by Señor Raul Moroni of Santiago, archived on [link], last accessed 1 May 2022. See also Martin Coombs, "Chilean Steam Locomotive List - Parte 4", p. 220-222, downloaded from [link], last accessed 8 April 2022. Works numbers were 1852-1857 in 1912.

A 1912 request for bids on six Tipo-bs to join three produced by Henschel & Sohn in 1909 induced replies from Arnold Jung, Berliner Maschinenbau, Borsig, Henschel, Orenstein & Koppel, and American Locomotive Company. Jung won the contract, which was signed on 15 May 1912.

Their initial duties supported construction, but they soon appeared on the EFE (State Railway), where they served into the 1950s..
