Originally designed to haul sugar cane, the Oahu Railway and Land company eventually extended its train service into Wahiawa to haul pineapple. In January 1909 the tracks were also extended onto Schofield Barracks and were used to facilitate Army troop movements. The troops called the train "Pineapple Limited" and used it as a means of transportation into Honolulu. Because cars were limited and the ride was unappealing and sometimes dangerous because of bad roads, the five-hour train trip was a pleasant alternative. The train usually pulled in one day and left the next. Passenger service ceased in the late 1930’s and didn’t return until World War II; it then continued until Dec 31, 1947.
