(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.
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 reported that the HSP felt 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."
Even with these deficiencies, the engines still brought a lot with them. According to the Discover Kilohana history, Baldwin 0-6-2STs in the Hawai'ian Islands were known as "'Bulldog Baldwins' for their squat, compact appearance and renowned pulling ability. At one point there were more than 20 of these engines in service on Kauai at the same time."
They were joined by near sister Manana in 1916 which used oil fuel; see Locobase 16510.
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. A 2020 update could not find any further information on this effort.

The American Sugar Corporation bought two wood-burning saddle-tanks in 1899 (Locobase 12319) for operation on their Honolulu Sugar Plantation. They proved successful and prompted another order in 1916, this time with the Baldwin standard oil-burning arrangement installed in a firebox lined with firebrick.
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.

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.
