In just 1.3 seconds, the Japanese shinkansen train will brake 'lightning fast' during an earthquake

According to the Mainichi newspaper on January 3, the East Japan Railway Company's earthquake early detection system will be installed in all 135 shinkansen bullet trains by March next year. The system will help shorten the response time from detecting an earthquake and activating the emergency braking system, from the current average of 3.9 seconds to 1.3 seconds.

New emergency braking system for shinkansen bullet trains to be applied from March next year

The emergency brake will be activated in the event of an earthquake of magnitude 5.5 or greater.

In this system, a bullet train running at 320 km/h would immediately stop after about 230 m from braking, a shorter distance than existing technology.

The new system was developed in collaboration with the East Japan Railway Company and the Railway Technical Research Institute.

Current shinkansen bullet trains make emergency stops about 20 times a year due to earthquake incidents. With the new system, that number could increase four times due to improvements in the sensor system.

Company President Yuji Fukasawa called the implementation of the new system a decision to prioritize safety. According to Mainichi , the shinkansen's earthquake safety system has been continuously improved since it went into operation in 1982.

Japan urgently searches for earthquake survivors

The announcement comes after a magnitude 7.6 earthquake struck central Japan on New Year's Day, with authorities reporting at least 64 deaths.
