Highlight

In this time of global environmental problems and overcrowding in cities, the value of railways is being reappraised because of their role as a means of transportation that can handle large volumes with excellent energy efficiency compared to automobiles or aircraft. The Shinkansen is Japan’s flagship high-speed railway, with a network that has been expanded in accordance with plans established by the Nationwide Shinkansen Railways Construction and Improvement Act. This has included steady progress on expanding the network over recent years, with the opening of the extension of the Hokuriku Shinkansen to Kanazawa in March 2015 and the launch of the Hokkaido Shinkansen to Shin-Hakodate-Hokuto in March 2016. These two new Shinkansen services include mutual direct trains, meaning through-train services that operate over more than one railway company jurisdiction. While the operation of these services is more complicated than those that only involve a single company, they still need to ensure that the Shinkansen operates reliably and that passengers can enjoy trouble-free services. To achieve this, the Shinkansen traffic management systems need to support safe and reliable operation by ensuring that services match customer needs. Hitachi has been involved in developments and improvements to the Shinkansen traffic management systems that ensure the trouble-free operation of these mutual direct trains.
