In 1970 two important events took place. First, Waialua Agricultural Co. announced that they planned to scrap their 0-6-2T locomotive No. 6 because rust and deterioration had reduced the engine to an unsightly liability and posed a danger to the local kids who played on her. John Knaus then contacted Bill Paty who was the manager of Waialua Agricultural Co. about saving and restoring the locomotive. John then contacted his boss, Captain Henry Davies, of the Naval Ammunition Depot, Lualualei about having the locomotive moved there since it had the only locomotive facility left on Oahu. This was followed by a letter to Ed Bernsten of the National Railway Historical Society seeking information on organizing a local chapter. John received approval to have No. 6 restored at Lualualei. He then talked to Nick Carter, another rail fan who had expressed interest in saving the Navy mainline on the leeward coast for an operating railroad.

On August 22, 1970, John Knaus, Nick Carter, Luman Wilcox and Ken Peale met at Coco’s Restaurant to discuss forming a local chapter of the NRHS. Wilcox was appointed to draw up the temporary by-laws. On August 27th an organizational meeting was held at Cocco’s with 15 people in attendance. Wilcox entertained a motion to organize forming a local chapter of the NRHS. Dr. Bob Kemble seconded and the motion was carried. Thirteen of the fifteen people present signed up. Nominated and elected were: Luman Wilcox for pres., Ken Peale for VP, Nick Carter for Secretary-Treasurer, and John Knaus for National Director. On Oct 9, 1970 the membership met to approve the By-Laws and Charter Night was set for Nov. 13th at Bishop Museum.

On Feb. 17th 1971 a Waialua Agricultural Co. trailer was used to transport WA Co. 6 to Lualualei. Waialua Elementary School students gave the old locomotive a send off before it left Waialua. No. 6 was a magnet that brought a group of talent to Lualualei shortly after. A boiler maker named Dave Griner, a welder named Dick Marshall and a machinist named Bob Haney were all joined by others who wanted to lend a hand. On October 13th the Hawaii Chapter of the National Railway Historical Society was granted a charter.

On Oct. 13, 1971 The State of Hawaii, Department of Regulatory Agencies granted the Hawaii Chapter of the National Railway Historical Society, INC. a charter of incorporation.

Now the use of Hawaii Chapter, NRHS posed a problem the name was too long and it really didn’t say anything about local railroading. So at a membership meeting on December 19, 1973, the members voted to use the name, Hawaiian Railway Society without severing itself from the NRHS.

One more significant date: On November 25, 1972, a Saturday, a dedication ceremony marked the restoration of No. 6. On hand were local dignitaries to celebrate the event. After 84 Sundays of restoration work, a dream came true.
