Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 9, p. 234. Works numbers were 4908 in December 1879 and 6102 in March 1882.
The KW&H was a Maui-based railroad that was the first to be opened in the Hawaiian Kingdom when Captain Thomas Hobron cut the ribbon in 1879. Lightly built at 20 lb/yard (10 kg/metre), the railway nevertheless opened up the sugar and pineapple planations to easy access to the port of Kahului.
And despite the petite dimensions more usually found in a plantation locomotive, the Kalakaua and its 1882 stablemate Claus Spreckels pulled trains providing common-carrier service. The little Forneys would remain in service all over the island well into the 20th Century. The Claus was donated in 1967 to Bernice Pauahi Bishop, who renamed it Kahakaloa. In 1985 it was leased to the Alexander & Baldwin Sugar Museum.
