and modelers. Ben Dillingham gave the group a 1st class coach #47 and an observation car #48, formerly the private parlor car named Pearl. The Kahuku Plantation Co. allowed the group to use their tracks from near Kawela Bay to Punaluu. The group ran excursions infrequently, renting a steam locomotive from Kahuku Plantation. In 1950, the last steam locomotive was retired and the H&HSL RR then used one of two ex-Navy diesels. In 1954, the plantation abandoned its railroad in favor of trucks thus ending the H&HSL RR. Due to a lack of money and enthusiasm the group was unable to remove their two coaches from the property, so a plantation official had them torched. The OR&L's Honolulu harbor branch, renamed the Oahu Railway, was used until December 31, 1971 for industrial operations. It served a Kalihi stockyard (until 1961), but chiefly hauled incoming Molokai pineapples from the wharves to the Libby, McNeil and Libby and California Packing Corporation (Del Monte) canning plants. The final section of the line was taken over by the US Navy in 1950. The Navy, especially during the Korean War and the Vietnam War, ran ammunition trains between the West Loch of the Pearl Harbor Naval Base, through the Ewa Plain, to the Lualualei Naval Ammunition Depot on the Waianae coast, preserving one of the most famous and scenic stretches of the railroad. The Navy switched to trucks, and the railroad property was abandoned in 1970. The Oahu Railway & Land Company merged with Hawaiian Dredging to form Dillingham. Historic preservation In that same year a small group of railroad fans on Oahu learned of the abandonment and petitioned the Navy to turn the line and equipment over to them. This body became the Hawaiian Railway Society (HRS) in 1970. Nicholas Carter, a charter member of the HRS and one of its founders worked with others in the early 1970s, nominating the former OR&L mainline from Ewa to Nānākuli to the National Register of Historic Places. On December 1, 1975, U.S. Senator Hiram Fong reported that this had been done. Today the tracks are owned by the State of Hawaii, while the HRS is the line's caretaker. The HRS continues to maintain and extend the right-of-way while running excursion trains from its station in Ewa. Currently, trains are scheduled for Saturday afternoons at 3:00 and Sunday afternoons at 1:00 and 3:00, running past the new
