JR companies are strengthening maintenance work, technological development, and human resource development in preparation for the aging facilities that support the Shinkansen in the near future.

Since the Tohoku Shinkansen and Joetsu Shinkansen will be opened in 2032 for 50 years, JR East plans to make a large-scale renovation from 2031, and will develop technology and develop human resources at the JR East General Training Center in Shirakawa City, Fukushima Prefecture. We have created a new facility to do this.

In the facility, concrete bridges with a length of 80 meters, tunnels with a length of 30 meters, railroad tracks, etc. will be built, and technological development such as robots for inspection will be promoted, and human resources for maintenance will be trained. ..



JR Tokai, which operates the Tokaido Shinkansen, is already proceeding with large-scale repairs such as repairing cracks found in concrete structures such as tunnels as a measure against deterioration.



Due to the spread of the new coronavirus infection, the construction period will be extended by two years and will be completed by 2024.



JR West, which operates the Sanyo Shinkansen, is planning a large-scale renovation work from 2028, and JR companies are strengthening anti-aging measures for the future.
