R East will install communication systems in train cars by around 2035 that let passengers contact onboard safety personnel. These personnel and station staff will be trained to ensure safe operations. [...] New safety measures will include using satellite data for operation of railroad crossing gates. This system will enable trains to stop automatically when an emergency button is pressed to prevent collisions. Autonomous driving is already planned for bullet trains on the Joetsu Shinkansen line linking Tokyo and Niigata, a city on the Sea of Japan. Expansion is eyed for the Hokuriku and Tohoku shinkansen lines as well.
