Hawaiian Sugar 2-4-2 "Columbian" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class Hanapepe (Locobase 11738)

Data from Baldwin Locomotive Works Specification for Engines, as digitized by the DeGolyer Library of Southern Methodist University Volume 18, p. 41. Works numbers were 12966 in October 1892 and 13676 in August 1893.

These two sugar-plantation engines were delivered with names Hanapepe and Waialeaa. The specs required each engine to manage 50 cane cars of 3 tons loaded weight each around very tight curves.

The former was sold in August 1941 to Koloa Plantation, which renamed it Kaluahono. 3 went to Grove Farm in January 1943 as their #4.

Class Olokele (Locobase 13002)

Data from Baldwin Locomotive Works Specification for Engines, as digitized by the DeGolyer Library of Southern Methodist University, Vol 29, p. 41. Works number was 28623 in July 1906.

This saddle tank joined two other locomotives of virtually identical dimensions that had been delivered in 1892 (Locobase 11738). Detail differences included a reduction in thickness of the boiler tubes from #13 WG to #12 WG, the use of magnesia sectional lagging on the boiler, Crosby safety valves instead of those manufactured by the works themselves. Baldwin, an increase in the boiler pressure, and a slight difference in weights. The spec continued to require the ability to haul 50 cane cars of 3 tons each.

The 4 was retired in August 1941.
