Waimanalo Sugar Company 0-4-2 Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class Lili (Locobase 11818)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 11, p 244. Works number was 6944 in September 1883.

J De Rivera was the purchasing agent for this locomotive, but it was delivered to the Waimanalo Company on Oahu and spent the next 50+ years toiling as a sugar-cane plantation workhorse. It's not clear from Connelly's Baldwin list when the 2 acquired the name Pokaa.

In 1948, Ward Kimball bought the Pokaa to run on his San Gabriel, Calif railroad.
