Honolulu Plantation 0-6-2 Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class Halawa (Locobase 12319)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 22, p 28 and Volume 54, pp. 414+. (Many thanks to Chris Hohl for his 18 March email pointing out the differences between the Halawa and the Manana and noting the existence of at least one more sister. ) Works numbers were 16438 in January 1899, 17687 in April 1900, and 43246 in April 1916.

Wood-burning Halawa and Waimalu were two saddle-tanks bought by the American Sugar Corporation for operation on their Honolulu Sugar Plantation. The working environment offered some challenges. Halawa faced grades of between 2% and 3 1/2% and curve radii of between 16-26 degrees. Each of the cane cars had a tare weight of 2,800-3,000 lb and would carry between 3 1/2 and 5 tons.

A note in the Baldwin specs said that the HSP said that the water tank was too small and that "Parmalee" suggested that the company adopt separate tenders. The equalizers between the main and rear drivers were badly worn. And the note included the nearly universal comment for logging and plantation locomotives: "Track is rough and springs should have one more plate."

They were joined by near sister Manana in 1916 which used oil fuel. Its bunker carried 600 US gallons (2,271 litres) of water and 350 gallons (1,325 litres) of oil. All three were members of a relatively large group of Baldwin plantation tanks built to the same design..

All of the engines received four-wheel tenders, but retained their saddle tanks. (Does this make them 0-6-2(ST)?.) A 1921 extra order from Baldwin delivered a new boiler for Waimalue; Halawa's came as a result of a 1924 extra order.

The two were transferred to the Kahuku Plantation and renumbered 9 and 8. In 1947, HSC sold both engines to Hawaiian Philippine Sugar in Silay City, Island of Negros, Philippines

After four more decades of work, the two were idled in 1998.

Their fates still linked, the two locomotives were to be purchased for restoration by the Kauai Plantation Railway. By 2015, funding had still to be identified and a crowd-funding site had been set up.
