Bullet Train In Japan

                                       The bullet train was first started in Japan in the year 1964. It started running between Shin and Osaka at a speed of 187 miles per hour. The train is a very convenient and fast mode of transportation. However,

Japanese Engineers had no solution to its sonic boom. The biggest problem was Sonic tunnel booms. It has taken billions of passengers since its opening but was disturbing and annoying thousands of nearby residents due to its sonic boom when it came out of the tunnel.

                                         Ultimately Japanese government asked the director of technical development Nakatsu with others to find a solution for making a bullet train quiet from a sonic boom.  Nakatsu was not only an Engineer but was also a Bird Watcher. He was also a good observer. He was in search of a suitable front design for the bullet train so that problem of the sonic boom can be solved.

                                         He observed the bird Kingfisher diving from air to water without making splashes. He shows that the kingfisher can do that because of its streamlined shape long pointed wedge-shaped beak. Accordingly, Japanese Engineers also conducted various shapes of the design and finally they shaped a bullet train front design practically identified to a Kingfisher's beak.

                              Sometimes Nature also gives solutions to Human problems.
