The Neiwan line was completed on 11 September 1951. It became a popular tourist site in the early 2000s.[clarification needed] A through-service between Neiwan and Taipei on Saturdays and Sundays started in 2004.
The section between Hsinchu and Zhudong was temporarily closed from 28 February 2007 in order to facilitate the construction of an electrified, dual-track, grade-separated route from Hsinchu through Zhuzhong and, via a new sub-branch line (the Liujia Line), to the newly opened Hsinchu HSR station.[1] Concurrently, three infill stations were added between Hsinchu and Zhuzhong. The upgraded section was reopened on 11 November 2011.[1][2]
The section past Zhuzhong remains single-track and unelectrified.[1]
