These Trains Had An Unexpected Issue #shorts

In the 1990s, Japan’s bullet trains caused a sonic boom when passing through tunnels due to air pressure. Inspired by the kingfisher bird, which dives without making a big splash, an engineer redesigned the train’s nose to resemble its beak. As a result, the sonic boom disappeared, and the trains could run faster without disturbing nearby residents.
