Class 3 (Locobase 14752)

Data from DeGolyer, Vol 63, pp. 229. See also Paauhau Sugar Plantation Company, Hawaiian Sugar Planters Association archives at and Prosper Quentin Tomich, "Sugar Plantations and their Railroad Era, 1879-1947", Hawaii: Perspectives on Hamakua History, (self-published, 2008, ISBN 978-0-615-25676-4), pp. 92-94. Works number was 54410 in January 1921.

This plantation's sugar mill was perched on a cliff 400 feet (121.4 m) above the ocean on the northern coast of the Big Island about 50 miles (80 km) from Hilo. Much of the cane came down from the fields in the foothills on a cane-car gravity-driven system of parallel tracks. As the full car came down one track toward the mill, its cable feed pulled its empty opposite number on the other track back up to the fields.

Water supply was only fitfully supplied by water courses in this part of Hawaii, so Paauhau management contracted with Hawaiian Irrigation Company to deliver 20,000,000 gallons of water per day and built two reservoirs.

The little (very) saddle tank shown in this entry moved cane cars on the level stretches closer to the mill. Prosper Tomich documents this engine's transformation into a prime move that used a Ford V-8 fueled by gasoline driving the transmission from a Best-60 tractor to turn the rear axle. The original side (coupling) rods turned the other two axles. Berlinda Rapozo Camara remembered later how noisy the engine was as it pulled her car full of schoolchildren to and from school. See Locobase 15492 for another Ford V-8 conversion, this time of a full-sized 2-6-0 in Louisiana.

By 1945, the railway was closed.
