The Bullet Train Brake That Triggers Before the Quake Hits

[00:00:00]Japan built a train brake that reacts before passengers even feel the worst shaking. The Shinkansen Earthquake Warning Network listens for fast primary waves, then instantly cuts traction power and commands emergency braking before the slower destructive waves arrive. That head start can be only a few seconds, but at 300 km an hour it matters. It is one reason high-speed trains can cross one of the world's most active seismic zones without treating every tremor like a catastrophe.
