I have never seen a bullet train in my life (dont tease me)
The design of the bullet train nose is similar to the aerofoil shape of the airplane wings. That shape allows for the air to flow freely along the nose i.e. the nose "pierces" the air.
I am forced to say "wonderful post! "
Exactly @rharphelle, its all aerodynamic. If the train or any object that moves through the air is not just shaped in such a way that the air glides gently through it, it will surely experience so much drag that will result to a reduction in speed. Thanks for taking time to read this article.
