Yes, for a MagLev train that achieves the fantasy of hyperloop (but is actually happening now). From my perspective, hyperloop and TBC are each 100% upside down in terms of their approach. America can only dream of 505km/hr interstate ground transport.
I'm writing this from aboard the Nozomi express Shinkansen at around 300km/hr, by the way. Just left 名古屋駅.
Hah, amused to be able to read kanji after so many years (nagoya-eki :P)
I have ridden on the Nozomi and it's a fantastically smooth ride. There are indicators of the current speed on the wagon passage doors and it is incredible when it achieves 270+ km/h and everything is passing by so quickly, and yet you can drink your beverage from a cup just fine, just like in an airplane :)
