Hawaiian 0-4-4 "Forney" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class Kinau (Locobase 11788)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 10a, p. 215.

Originally to be called Kalamanui, this little tank was renamed in Philadelphia. Kinaut was sold to the Kahului Railroad in September 1884 and renumbered 2.

Some time later, the Kinau gave up one of its trailing trucks in favor of a six-wheel tender, thus becoming an 0-4-2.
