In just 1.3 seconds, Japan's shinkansen trains will brake 'lightning fast' during an earthquake.

According to the Mainichi newspaper on January 3rd, East Japan Railway Company's earthquake early detection system will be installed on all 135 of its Shinkansen bullet trains next March. The system will help shorten the response time from earthquake detection to emergency braking activation, from the current average of 3.9 seconds to 1.3 seconds.

A new emergency braking system for Shinkansen bullet trains will be implemented starting next March.

Emergency braking will be activated in the event of an earthquake with a magnitude of 5.5 or higher on the Richter scale.

In this system, a bullet train traveling at 320 km/h would come to a complete stop approximately 230 meters from the brake pedal, a shorter distance than with existing technology.

The new system was developed through a collaborative research effort between East Japan Railway Company and the Railway Engineering Research Institute.

Current Shinkansen bullet trains experience approximately 20 emergency stops per year due to earthquakes. With the new system, the number of stops could increase by four times due to improvements in the sensor system.

Yuji Fukasawa, president of the company, called the deployment of the new system a decision to prioritize safety. According to Mainichi , the shinkansen's earthquake-related safety system has been continuously improved since it began operating in 1982.

Japan urgently searches for survivors after earthquake.

The announcement comes after a powerful 7.6 magnitude earthquake on New Year's Day 2024, with its epicenter in central Japan. Authorities reported that at least 64 people died in the earthquake.
