Tamsui–Xinyi line

A sign at Taipei Main Station in 2007. The line, then known as Tamsui and romanised as Danshui line, operated to Nanshijiao and Xindian.

For 15 years, trains operated between Tamsui and Xindian via the southern part of the current Songshan–Xindian line, making it the longest-serving former service of the system, followed closely by a 13 year service from Beitou to Nanshijiao via the southern part of the current Zhonghe–Xinlu line. With the completion of Dongmen station, Xinyi Line, and Songshan Line, both services ended, placing the current form of the Tamsui–Xinyi line into effect.
