Japanese bullet trains long noses
You know why japanese bullet trains have such long noses. Well if you think it's because of speed ,then you will be wrong. As china and Europe also has bullet trains, but they don't have long noses .you see in japan,there are a lot of tunnels.
And by the 1990s, when trains would go through these tunnels at 200 miles per hour, it would make extreme sound waves, creating sonic booms which would disturb nearby neighborhoods.and Japanese engineers started reasearch to solve this problem .and found out that ,kingfisher birds also dive into water at a speed of 25 miles per hour ,but doesn't make much sound. Which was possible because of it's long pointy nose. And thus ,they took inspiration from it ,and made the nose longer.
