Class Details by Steve Llanso of Sweat House Media

Class Waialua (Locobase 12310)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 22, p. 1. Works numbers were 16386-16387 in December 1898.

The second of these small Ten-wheelers was named Kahuka. They faced curves of 75 metres radius and scaled grades of up to 4 1/2% (238 ft/mile)..

Both locomotives had long careers. Kahuka was scrapped in 1936 while Waialua carried on until 1948.
