Tamsui-Xinyi Line eastward extension delayed in Taipei

台北淡水信義線東延延期

Mayor Chiang Wan-an visits construction work mired by difficult geological conditions



According to UDN, tunneling progress is just two meters per day. This is slow going for the planned 1.4 km extension, which has been billed by MRT officials as the most difficult project in the history of Taipei MRT.

Construction progress now stands at just 70% and has overcome difficulties such as a shallow ground layer with high water content, requiring strengthening with cement before excavation. Digging deeper down, hard rock plates were discovered.



The eastward extension of the Tamshui-Xinyi Line from Xiangshan Station requires a shield tunnel extending to Yucheng Park with the total cost of the project pegged at NT$9.3 billion (US$305 million).

An underground station, RO1 Guangci-Fengtian Temple Station, will serve as the terminus of the Tamsui-Xinyi line and will include traffic dispatch operations.
