At its two ends, the Taebaek Line connects to the Jungang Line and Yeongdong Line. The line was originally two spur lines, which were built across difficult mountainous terrain in stages, before a connection was built. The line includes the steepest section of the South Korean network, a short parallel line that is operated as a second track on the section includes South Korea's longest spiral tunnel. The centerpiece of the last-built section west of Taebaek, is a tunnel that was the longest in South Korea at the time of its construction, and Chujeon Station at the eastern end of the tunnel is the highest altitude in South Korea at . In passenger traffic, the line is served by cross-country passenger trains connecting the capital Seoul with Korea's east coast. In freight traffic, while coal transport declined, the line carries significant cement transport. In the winter, regular special trains take tourists along the scenic route. ==History== In 1949, the Economic Cooperation Administration, the United States government agency administering the Marshall Plan, also launched a plan to revive South Korea's economy, which included the construction of new railway lines. One new line under the plan was a line from Jecheon to the coal mines around Yeongwol and Hambaek to the east.〔 Construction started in August 1949, but was interrupted by the Korean War in 1950, work resumed in October 1952.〔 The Jecheon–Yeongwol section, with an original length of ,〔 went into service as the Yeongwol Line on December 30, 1955. On March 9, 1957, the line was extended by to Hambaek, and was renamed the Hambaek Line. Following the 1961 coup, the Supreme Council for National Reconstruction started South Korea's first five-year plan, which included a construction program to complete the railway network, to foster economic growth. One of the first lines completed under the plan was the Hwangji Branchline, which would later become the eastern end of the Taebaek Line.〔 The long spur from Baeksan on the Cheoram Line (today the Yeongdong Line) to Hwangji (renamed Taebaek in 1984) opened on December 20, 1962.〔 Another project under the five-year plan was a railway between Yemi on the Hambaek Line and Jeongseon.〔 The section climbing the mountains around Hambaek to Jeongsan (renamed Mindungsan in 2009),〔 which would later become part of the Taebaek Line, was completed on December 19, 1966, and the entire railway from Jecheon to Jeongseon was renamed the Jeongseon Line, with the short Yemi–Hambaek branch retaining the Hambaek Line name.〔 A long track section on the climb after Yemi is the steepest on South Korea's network at 30.3‰. Also on December 19, 1966, a branch from Jeongsan to Gohan opened as the Gohan Line, which would also become part of the future Taebaek Line.〔 The Jeongseon Line was completed to Jeongseon on January 20, 1967; this section and its later extensions form the present-day Jeongseon Line.〔 The long gap between the Gohan and Hwangji branch lines was plugged on October 16, 1973, when the entire railway from Jecheon to the junction with the Yeongdong Line at Baeksan was renamed the Taebaek Line.〔 The centerpiece of the last section was the long Jeongam Tunnel,〔 which was the longest in South Korea before the opening of longer tunnels on the Jeolla Line and the Gyeongbu High Speed Railway, and Chujeon Station at the eastern end of the tunnel is the one on the highest altitude in South Korea at above the sea. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Taebaek Line」の詳細全文を読む スポンサード リンク
