臺北工場汽車修理工場、塗工場及遷車台於明治42年(1909)創建，為鐵道部因應臺灣 西部縱貫鐵道通車後，繁忙修理業務所進行的增建工事。2005年間，由於三座建築遺構 恰巧位於臺北捷運松山線與機場捷運工程交會位置，因此進行了臺灣第一座古蹟搬遷保 存工作。本文藉由鐵道工廠的遷移與遺構挖掘的成果，說明鐵道遺產保存的最高策略實 為遺產「真實性(Authenticity)」的追求與再現，並透過動態的考古發掘記錄、符合時勢的 遺構保存方法，以及跨領域的遺產研究加以落實。最後，經由日治初期臺灣糖、米及產 業發展的對照，說明鐵道工場遺構的迅速擴張和消失現象，實為近代工業遺產獨具且突 出地現代化革新屬性的具體反映。

The Western Rail Line (Taiwan Trunk Line) in Taiwan was completed in 1908. In 1909, in order to cope with the rapidly rising demand for repairs, the Railway Administration of the Japanese colonial government launched a project to extend maintenance facilities encompassing new workshops, paint shops and transfer table (turntable) in the Taipei Railway Factory. This historical site is situated in the same location as the new Taipei MRT (Mass Rapid Transit) station. The conservation strategy represents the first implementation of a removing conservation plan for Cultural Property in Taiwan since it was enacted in 2005. This article focuses on the best conservation strategy for railroad heritage and explores the representation of “Authenticity” of remains (consisting of the site itself, building, components, machinery and setting). In practical terms it consists of interactive archaeological exploration, conservation intervention in accordance with circumstances, and interdisciplinary research. Through the contrast of early industrial development during the beginning of the Japanese Colonial Period, it should be concluded that the expansion and disappearance of the first generation Taipei Railway Factory demonstrates the unique and outstanding value of industrial heritage: modernity.
