Work on monster tunnel to begin for maglev train linking Tokyo to Nagoya

posted on December 12, 2015

Construction of a mammoth 7.7-kilometer tunnel cutting through the Southern Japan Alps will begin Dec. 18 as part of an ambitious project to link Tokyo to Nagoya with a maglev train line by 2027.

Twenty-five kilometers of tunnel are required in total, but the first stretch will be the biggest hurdle facing Central Japan Railway Co. (JR Tokai) in setting up the highly anticipated high-speed Linear Chuo Shinkansen line connecting Shinagawa in Tokyo with Nagoya Station.

A ground-breaking ceremony will be held Dec. 18 in Hayakawa, Yamanashi Prefecture, JR Tokai said Dec. 9.

The deepest part of the tunnel, at 1,400 meters, is expected to pose a number of engineering hazards; groundwater shooting out of fissures at extreme pressure, for example. This will likely be the most troublesome portion of the construction project.

"We will do our very best in building this tunnel, as we have the responsibility of protecting the main artery of the train line in the future," JR Tokai President Koei Tsuge said in a Dec. 9 news conference.

The operator started work on areas surrounding Shinagawa and Nagoya stations last December, but this will be the first time for construction to begin on the actual train line.
