The origin of the project

The transportation system along the Taipei–Yilan Corridor—including National Highway No. 5, Provincial Highways No. 2 and No. 9, and Taiwan Railways—has long faced demand that exceeds its capacity.In recent years, extreme weather events and earthquakes have also caused repeated disruptions to external transportation serving eastern Taiwan, significantly affecting travel safety and reliability.To address these challenges, there is a clear need to develop a stable and reliable rail system to improve external connectivity for Yilan, Hualien, and Taitung.

Plan outline

• Route: The proposed route extends eastward from Nangang Station, bypasses the Feitsui Reservoir catchment area, and passes through Xizhi, Pingxi, Shuangxi, and Gongliao in New Taipei City, as well as Toucheng and Jiaoxi in Yilan County. The line terminates at a station in Yilan, with a total length of approximately 60.6 kilometers.
• Facilities: The HSR Yilan Station is planned to be located south of the Yilan County Administrative Center. A stabling and maintenance depot is also planned on the northern bank of the Lanyang River.

Expected benefit

• To relieve long-standing congestion and capacity constraints along the Yilan–Taipei transportation corridor.
• By enabling convenient transfers at the HSR Yilan Station to Taiwan Railways services to and from Hualien and Taitung, overall service capacity will be enhanced and the resilience of the eastern rail network strengthened.
• The HSR Yilan Line is a key project supporting the vision of a high-efficiency, round-island railway network that connects Taiwan within four 90-minute travel zones. It is also an important infrastructure initiative under the government’s Balanced Taiwan policy.
