Map with all coordinates: The Shin-Tanna Tunnel ( Japanese. 新 丹 那 ト ン ネ ル ; Shin-Tanna tonneru ) is a railway tunnel on the Japanese island of Honshū . It is located in Shizuoka Prefecture on the JR Central operated high-speed Tōkaidō-Shinkansen line . The double-track tunnel is 7,959 km long and connects Atami with Kannami . It leads on the northern edge of the Izu Peninsula through tectonically unstable extensions of the Taga volcano with several faults . After construction began in August 1941, it was dormant for almost two decades. Finally, the tunnel was opened on October 1, 1964.
The Tanna Tunnel on the Tōkaidō main line, opened in 1934, runs parallel to this .
history
The Tanna Tunnel was opened in 1934 after 16 years of construction. The outbreak of the Pacific War three years later resulted in an enormous increase in freight traffic, some of which was at the expense of long-distance passenger traffic. For this reason, the Ministry of Railways began planning a standard gauge "new trunk line" (Japanese 幹線 , Shinkansen ) in 1939 . It was supposed to connect Tokyo with Shimonoseki to facilitate the transport of goods to the Asian mainland; A subsequent tunnel to Korea was also considered . The project also included an additional tunnel between Atami and Kannami, construction work began in August 1941. Engineers and workers lived by the western tunnel portal in a newly built settlement called Shinkansen , which still bears this name today. Due to the increasingly bad course of the war, work had to be stopped in 1943. Up to this point in time, 647 m had been drilled on the east side and 1,433 m on the west side.
A decade after the end of the war, the Japanese State Railways planned a new high-speed line that took up parts of the earlier Shinkansen plans. For this purpose, construction work on the Shin Tanna Tunnel was resumed in 1959. In contrast to the Tanna tunnel, these ran largely without problems. Responsible for this were new knowledge about the difficult geological conditions and the application of the New Austrian Tunneling Method . After four years and four months, the work was completed and the tunnel was opened on October 1, 1964 together with the rest of the Tōkaidō Shinkansen .
