Editing Hawaii (section)

===Rail===
At one time Hawaii had a network of railroads on each of the larger islands that transported farm commodities and passengers. Most were {{RailGauge|3ft}} [[narrow gauge]] systems but there were some {{RailGauge|2ft6in}} gauge on some of the smaller islands. The standard gauge in the U.S. is {{RailGauge|4ft8.5in}}. By far the largest railroad was the [[Oahu Railway and Land Company]] (OR&L) that ran lines from Honolulu across the western and northern part of Oahu.<ref name="ReferenceA">{{cite book |title=Hawaiian Railway Album—WW II Photographs Vol 2 |author1=Norton Jr., Victor |author2=Treiber, Gale E. |year=2005 |publisher=Railroad Press |location=Hanover, PA}}</ref>

The OR&L was important for moving troops and goods during World War II. Traffic on this line was busy enough for signals to be used to facilitate movement of trains and to require [[wigwag (railroad)|wigwag]] signals at some railroad crossings for the protection of motorists. The main line was officially abandoned in 1947, although part of it was bought by the U.S. Navy and operated until 1970. {{convert|13|mi|km|spell=In}} of track remain; preservationists occasionally run trains over a portion of this line.<ref name="ReferenceA"/>

[[Skyline (Honolulu)|Skyline]] is an elevated passenger rail line operated by [[Honolulu Authority for Rapid Transportation|HART]], a semi-autonomous agency of the [[Honolulu County, Hawaii|City and County of Honolulu]]. It was built with the intention to relieve highway congestion.<ref>{{cite web |url=https://www.transit.dot.gov/sites/fta.dot.gov/files/docs/HI_Honolulu_HCT_Profile_FY17_0.pdf |title=High Capacity Transit Corridor Project: Honolulu, Hawaii |publisher= |date=December 2015 |access-date=26 June 2022}}</ref> A portion of Skyline opened for service in 2023, with the next phase expected to open in October 2025, and the final phase in 2031.<ref>{{Cite web |last1=Aquino |first1=Jamm |last2=Russell |first2=Cindy Ellen |date=2023-06-30 |title=Ridership commences on Honolulu's rail system |url=https://www.staradvertiser.com/2023/06/30/photo-gallery/ridership-commences-on-honolulus-rail-system/ |access-date=2023-07-02 |website=[[Honolulu Star-Advertiser]]}}</ref>
