"Oahu Railway & Land Company
The first section of this 3ft (914mm) gauge network of lines opened in 1889. At its greatest extent, the line left Honolulu, skirted Pearl Harbour and headed for the west coast of the island. It then followed the west and north coasts as far as Kahuku. A branch from Waipahu ran inland to Halemano. The network was heavily utilised during the Second World War, notably for access to Schofield Army Barracks and Lualaulei Naval Ammunition Depot. However, general traffic was insufficient to ensure the survival of the line after the War, and operations outside the area of Honolulu and the Harbour ceased in 1947. The little traffic that remained lingered until 1972, when the last section of line finally closed to commercial traffic.
