It was called the bullet train because it was rounded in front, but every time it went into a tunnel it would build up a pressure wave, and then it would create like a sonic boom when it exited.
See nimetati kuulrongiks, sest selle esiots on ümar. Iga kord, kui see tunnelisse sisenes, tekitas see õhulaine, mis põhjustas kõrvulukustava kõmaka, kui rong tunnelist väljus.
