Hawaiian Railway Society, Heritage railway in Ewa, Hawaii, US

The Hawaiian Railway Society is a heritage railway in Ewa that operates train rides on three-foot narrow gauge tracks while maintaining a collection of vintage diesel locomotives and historical equipment. The restored route connects Ewa to Nanakuli and displays rolling stock from different periods of Hawaii's railroad era.

The organization was founded in 1970 when railroad enthusiasts came together to save locomotive No. 6 from being scrapped by Waialua Agricultural Company. From this rescue effort grew an institution that now documents Hawaii's railroad past.

The site displays a Merci boxcar, one of 49 gifts from French railways to the United States after World War II. This car tells a story of international friendship and draws visitors interested in cross-border railway history.

The site operates weekend train rides where visitors can explore historical routes and vintage trains. Comfortable clothing and sun protection are advisable since rides take place in the open air over extended periods.

Locomotive No. 6 of the Waialua Agricultural Company is the only locomotive built in the state of Hawaii; it was rescued in 1970 after rust made it a hazard to children playing on it, and it was restored over 84 Sundays of volunteer work.
