This past week I visited Japan. I have a video of the Japanese bullet train a.k.a the Shinkansen. The Shinkansen runs up to 300 km/h or about 186 m/h. I live in Korea and the Korean high speed train, the KTX, runs at about the same. In Korea, there is never any warning when a train passes by. In Japan, however, an announcement is aired whenever one is passing by. The video below shows a short Shinkansen.
