High-speed trains have long, aerodynamic noses to prevent tunnel boom, a phenomenon where air pressure builds up inside tunnels when trains enter at high speeds, causing loud explosions; engineers solved this by designing the train's front to guide air smoothly inside, eliminating shock waves and pressure waves.

Why Bullet Trains Have That Long Nose #stem #engineeringAdded:
At high speed, this train can create an explosion of air. When it enters a tunnel, air has nowhere to escape. That pressure releases as a loud boom. So, engineers redesigned the front to guide air smoothly inside. No shock wave, no explosion, just perfect design.
