Japan’s bullet train faced a serious noise problem when it began expanding through tunnels.
What made it strange was that nothing was actually broken.
When high-speed trains enter tunnels, they create powerful pressure waves that can turn into explosive shockwaves at the exit.
Engineers tried barriers, tunnel modifications, and speed restrictions — but the problem wasn’t a defect. It was physics.
This video explains what was really happening inside those tunnels, why conventional fixes failed, and how an unexpected insight inspired a solution that changed high-speed rail design worldwide.
