East Railway Improvement Project (Completed)
East Railway Improvement ProjectIn order to speed up development of eastern Taiwan's resources and to address the increased traffic needs there, the government decided to modernize the railway system in the region. The first priority of the project was to electrify the route between Taipei and Hualien. The next was to improve the route
between Badu in Keelung and Taitung City, by changing its 37kg rail to 50kg rail, automating its traffic signals and turning part of the route into double-track. The project also included the construction of the Hualien Coach Yard. This project involved a 337-kilometer stretch of railway, from the Badu Station, to
the stations of Su-ao, Hualien and Taitung Station. Work began in June 1998. On July 4, 2003, the part of the project that involved electrification was completed and services commenced. Before the end of December 2004, the whole project was completed. The total cost of the project was NT$43.691 billion.
New Guanyin TunnelBecause this line of railway passed through areas especially prone to landslides, tunnel construction was key. The New Guanyin Tunnel and the New Yongchun Tunnel were among the most challenging to build.

New Guanyin Tunnel:
This tunnel is located between Wuta and Hanben of Yilan County. At 10,307 meters, it is the longest double-track railway tunnel in Taiwan. Because of the local geology and terrain, two adits were added to the entrance areas to increase excavation surface to ensure good ventilation of the tunnel after completion. This was fundamental to the success of the construction of the entrance sections.

New Yongchun Tunnel:
This tunnel is located between Yongle and Dongao in Yilan County. On October 24, 1998, part of the construction near the south entrance collapsed due to water inundation. The inundation volume once reached 80 cubic meters per minute, and as much as 22,000 cubic meters of earth and rocks slid down. What's more, the inundation continued at a rate of 25 to 30 cubic meters per minute. Four years and some 70 engineering meetings later, the method of hot bitumen grouting was chosen
to address the problem in consideration of the site's level of high-pressure inundation. The problem was finally solved. The RRB applied the concepts and principles of the New Austrian Tunneling Method-making the designs as construction proceeds, and
choosing a construction method suitable for the geological conditions or improving the geological conditions to suit the construction method.
