NAGOYA -- Central Japan Railway Co. (JR Central) opened the construction site for the maglev shinkansen train's Nagoya Station to members of the media in the city's Nakamura Ward on March 7.
The new Linear Chuo Shinkansen maglev train line is scheduled to start passenger operations between JR Shinagawa Station in Tokyo's Minato Ward and JR Nagoya Station in 2027. The trains will run at a maximum speed of around 500 kilometers per hour.
JR Central showed construction work under the elevated railway tracks and platforms of the Tokaido Shinkansen bullet train line to build underground walls to support the new station facilities, which will be constructed about 30 meters below ground.
Workers are drilling vertical holes 1.5 meters wide to a depth of 75 meters, then inserting steel rods into the holes and injecting concrete into them to make columns that will create a wall. Large cranes are normally used for such drilling, but as the work site on the surface beneath the Tokaido Shinkansen line is only 5 meters high, specialized machines are being used instead.
The work is being carried out around the clock without obstructing train services on the Tokaido Shinkansen line. Wall construction -- made difficult in part due to soft ground -- is about 90 percent complete after work started in December 2016.
Akira Deguchi, head of the Aichi construction work office of JR Central, said, "While ensuring safety, I want the construction to proceed with each member remaining vigilant."
