Hawaiian Agricultural Company 0-6-2 Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class Hi'iaka (Locobase 11511)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 26, p. 216. Works number was 23632 in January 1904. See the University of Hawaii's account of the Kau Sugar Company's operations at []

Locobase was surprised to see soft coal specified for this sugar-cane locomotive, which was one of many purchased by W G Irwin on behalf of Hawaiian agricultural companies. It was named for the goddess Pele's sister (Hi'iaka'i-ka-poli-o-Pele) and went to work on the southwest corner of the Big Island. Although the plantation tried to grow several other crops (sisal, Sea Islander cotton, wine grapes, tobacco, and pineapple), all failed for any number of reasons and sugar proved to be the mainstay.

Hi'iaka was sold in 1940 to Honokaa Sugar Company, who retained her name.
