A: Japan operates some of the world's fastest electric trains, which travel in excess of 200 miles per hour. The trains have an excellent safety record, but one problem has nagged engineers for years. When a train passes through such a tunnel at high speed, it compresses the air in front of the engine. Upon leaving the tunnel, this air rushes outward, creating a loud thunderclap, or sonic boom. Nearby windows rattle, and people are awakened by the noise. Japan has strict laws on sound pollution, and design engineers sought a solution to the "tunnel boom" problem. They found the surprising answer in nature—the kingfisher. What interested engineers? Wind tunnel experiments verify that the kingfisher's bill is ideally shaped for a smooth, streamlined transition from air into water. This drastic change in pressure is similar to the change a bullet train experiences when emerging from a tunnel into the open air.
