Bolivian State 2-8-0 Locomotives in Bolivia
Class Details by Steve Llanso of Sweat House Media
Class 5 (Locobase 20003)
Data from 1947 Locomotive Cyclopedia tables. [
], accessed 19 August 2007. Works numbers were 44424-44427 in February 1909.
Compared to other metre-gauge Moguls, this was a heavy and powerful locomotive with a sizable cylinder volume and lots of firebox heating surface. A high boiler pressure setting meant a hard-working boiler.
The mines were a major source of tin in Bolivia in the early 20th Century and, hence, the world. See Norman Gall, "Bolivia: The Price of Tin" (June 1974) published on [] (June 14 2004). The locomotive's name was derived from the Siglo XX mine, which was the scene of near-constant labor strife from the time of Patino's acquisition in the 1910s through the 1960s. The mine was the site of what has been described as the worst massacre of workers in Bolivian history on 24 June 1967.
