How kingfisher saved bullet trains from shutting down

Along with this, people around the place from where this train used to pass used to face a lot of trouble. Japanese engineers quickly discovered the cause of this ‘tunnel boom’. When the train leaves the tunnel, due to the closed space, it pushes the air forward. This creates an air pressure wave. The train comes out of the tunnel like a shot from a gun. This generates a sound wave of more than 70 decibels and has an effect up to a distance of 400 meters in all directions. The reason was found but now the problem was how to solve it.
how miracles happened
Reducing the speed of the train or not passing through the tunnel was not an option. But nature had a solution for this. Japanese engineers caught sight of the kingfisher bird, which hunts fish in water at high speed. Its beak design proved to be a boon for Japanese engineers. Japanese engineer Eiji Nakatsu, a bird watcher, designed the front part of the bullet train on the lines of a kingfisher’s beak. His design worked. The tunnel boom problem of the bullet train is over and the local people heave a sigh of relief. Due to this the fuel efficiency and speed of the train also increased.
This once again proved that there is no greater engineer than nature. Kingfisher is a small colorful bird that dives into the water to catch its prey. Its beak is narrow from the front and becomes wider towards the back. This helps it to dive into the water. Japan had made high-speed train in 1964 itself. It is still considered a gem of engineering. He put bullet trains on the track by continuously increasing the speed, capacity and safety. Japan Railway East’s E5 bullet train runs at a speed of 320 km/h and travels from the capital Tokyo to Shin-Aomori.
