Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 23, p. 1. See also the "McBryde Sugar Company History" entry by the Hawaiian Sugar Planters' Association Plantation Articles at [] . Works number was 17686 in April 1900.
Quite small double-ender saddle tank with 4-wheel tender trailing behind. Soon after its arrival on Kauai Island, Hawaiii, the plantation shop removed the front truck. Locobase suspects it was deemed responsible for derailings. In any case, the Wahiawa was sold to the Grove Farm. In 1907, Grove Farm sold the engine to the Kauai Railway as their #2.
The plantation was formed in 1899 through the merger of the Eleele Plantation, McBryde Estate, and Koloa Agricultural Company. According to the Plantation Archives: "MSC had several major obstacles to overcome in the early stages of its existence. Not only was the company undercapitalized, but the terrain was extremely rocky and, as common for the leeward side of the island, there was a clear lack of water. As evidenced by early financial records, 'Rock Removal' was a rather large expenditure and many extra laborers were needed to clear the fields."
