simple question, 320km/h is the current "high speed" spec on new lines but stuff like HS2 and some lines in China are being built for 360km/h and some trains designed for up to 400km/h and test runs reaching far above that
as i dont think supersonic trains are gonna be a thing, whats prob the realistic could we see actual passenger trains reaching in the next 50 or so years?
