Yilan Line (Taiwan Railways Administration) The Yilan Line is a conventional passenger and freight railway line operated by the Taiwan Railways Administration connecting the Greater Taipei region with northeastern Yilan County and Ilan coastal areas. It links major nodes including Badu Station, Keelung, Taipei Main Station, Suao, and forms part of the northeastern corridor serving commuters, tourists, and freight traffic to ports such as Su'ao Port.

Overview

The Yilan Line forms a critical segment of Taiwan's eastern coastal rail network between the western Western Line (Taiwan) junction at Badu and the eastern terminus at Su'ao. It interfaces with national transport nodes like Taipei Main Station, Keelung Station, and the Hualien–Taitung Line via connecting services, contributing to regional accessibility for destinations including Yilan City, Luodong Township, and the scenic Northeast Coast National Scenic Area. Managed by the Taiwan Railways Administration, the corridor supports intercity expresses, local commuter trains, and occasional freight movements to industrial facilities in Keelung and Suao.

History

Construction of the Yilan corridor began during the Japanese rule of Taiwan era to improve access to northeastern resources and ports, with phased openings in the 1910s–1920s under colonial railway planners linked to projects like the southern extension of the Taihoku Prefecture rail network. Post-World War II administration by the Republic of China (Taiwan) saw rehabilitation works coordinated by the Ministry of Transportation and Communications (Taiwan) and the Taiwan Railways Administration. Major milestones include double-tracking and electrification campaigns in the late 20th and early 21st centuries that mirrored national railway modernization programs similar to projects on the Pingtung Line and Western Trunk Line. The corridor has endured impacts from natural disasters such as the 1999 Jiji earthquake and typhoon-related landslides, prompting resilience upgrades overseen by agencies including the Central Weather Bureau and the National Science and Technology Council.

Route and Infrastructure

The line departs the metropolitan rail junction at Badu Station and follows the northeastern coastline, traversing tunnels, viaducts, and cuttings across the Keelung River basin, the Xiaojiang River, and the foothills of the Snow Mountain Range. Engineering works incorporate structures comparable to those on the South Link Line and employ signaling systems interoperable with TRA’s regional standards. Key infrastructure elements include double-track sections near urban nodes, single-track older segments retrofitted with passing loops, and electrified overhead catenary at 25 kV AC consistent with TRA electrification on lines like the West Coast Main Line projects. Maintenance regimes coordinate with the Directorate-General of Highways and local authorities in Yilan County for slope stabilization and drainage to mitigate landslide risk.

Stations

Stations along the line serve urban centers, tourist gateways, and rural townships including Badu Station, Keelung Station, Qidu Station, Dingpu Station, Taoyuan, Suao Station, Yilan Station, Luodong Station, and ancillary halts providing access to attractions like the National Center for Traditional Arts and the Taipingshan National Forest Recreation Area. Several stations have been modernized with accessible platforms, integrated bus interchanges linked to the Taiwan High Speed Rail feeder network, and facilities for bicycle parking and ticketing compatible with the EasyCard and national fare systems.

Operations and Services

TRA operates a mix of service patterns on the corridor: commuter locals, regional "Chu-Kuang" and "Tze-Chiang" express equivalents, and seasonal tourist specials coordinated with the Taiwan Tourism Bureau for festivals such as the Yilan International Children's Folklore and Folkgame Festival. Timetables integrate with intercity connections at Taipei Main Station and freight slots aligned with port schedules for Keelung Harbor and Suao Port. Operations adhere to safety oversight by the Ministry of Transportation and Communications (Taiwan) and employ dispatch coordination similar to practices on the East West Line.

Rolling Stock and Maintenance

Rolling stock deployed includes TRA electric multiple units and locomotives comparable to models used across the network such as EMU series employed on the Western Line and diesel units for non-electrified spur services. Maintenance facilities for the Yilan corridor utilize depots and workshops with capabilities shared with TRA’s regional maintenance hubs in Keelung and Luodong, following standards influenced by international suppliers and domestic engineering groups, and coordinated with the Industrial Technology Research Institute for materials and condition-monitoring technologies.

Future Developments and Upgrades

Planned upgrades involve further capacity increases through additional double-tracking, signaling enhancements adopting European Train Control System-like technologies, station redevelopment projects to improve multimodal integration with Taiwan High Speed Rail and regional bus networks, and resilience investments to counteract typhoon and seismic hazards. Proposals under discussion by the Ministry of Transportation and Communications (Taiwan) and local governments include corridor realignments, grade-separation works, and tourism-oriented service expansions linked to initiatives by the Yilan County Government and the Tourism Bureau.
