Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 23, p 147. Works number was 18396 in November 1900.
See Locobase 14753 for information on the KSC. Working in sugar cane fields dictated the use of a Baldwin-provided 10" (254 mm) diameter Radley & Hunter spark-arresting stack. The boiler was enclosed by a planished jacket of rust-resistant "Russia Iron" (see Locobase 11179 for a description of this 19th century technique for protecting a boiler.)
A 1946 roster showed the Koloa still on the job in Kaua'i almost five decades later.
