JR East Japan announced the Tohoku Shinkansen plan, which has no speed improvement compared to the previous one.The report mentioned that JR East announced the design of the next-generation new car E10 series for the Tohoku Shinkansen, which is scheduled to be put into operation in 2030. The plan is not to further increase the length to 360 kilometers, but to maintain it at the current 320 kilometers, and it is still a 10-car grouping.
One point of this Shinkansen upgrade is the interior of the carriage. In response to the increasing demand for mobile office work, a new 2+2 layout "TRAINDESK" has been installed, providing high-speed WiFi, larger tables and privacy partitions between seats.
The Shinkansen is subject to the "flaws" of being built too early and the technical standards of the line are not very high. The new generation of new cars has been unable to achieve new breakthroughs in the maximum operating speed. However, the specific internal design and performance are constantly being improved.
Prior to this, my country's independently developed new generation of high-speed rail flagship model was unveiled. The CR450 EMU set a new world high-speed rail speed record with a test speed of 450 kilometers per hour!
