台糖公司「南北平行預備線」的建設計畫於1950年8月，當時正值韓戰爆發、中共亟欲解放臺灣之際，臺灣情勢可謂無比險峻。台灣政府為了國防軍事防禦的需要，命令臺糖公司將所屬各廠的鐵道進行南北串連，著名的南北線鐵道因而建成。南北線北起臺中站，南至高雄籬仔內站，全長260餘公里，本文先就介紹了南北線鐵道的緣起、興建內容、變遷發展歷史，其後再就鐵道遺產的文化景觀價值進行總結。（全文請見《實構築季刊》08期）

The construction of the North-South Parallel Line Railroad by the Taiwan Sugar Corporation began in August 1950. It coincided with the outbreak of the Korean War. It was a very dangerous period in Taiwan due to the threat posed by the Chinese Communist Party to liberate the island. Due to national security, the Taiwanese government ordered roads and railroad connecting factories of the Taiwan Sugar Corporation to be linked. This resulted in the formation of the famous North-South Parallel Line route. The line runs from Tai-Chung Station in the north to Li-Zih-Nei Station in Kao-Hsiung in the south, a total of 260 kilometers. This article introduces the history of the rise, construction and development of the North-South Parallel Line, and finally summarizes the values of this special cultural landscape.
