Hello, Japan is the first country in the world to build a practical high-speed railway. On June 1 964,65438+1October1day, the Tokaido Shinkansen was officially opened for operation. The running speed of the high-speed train reaches 2 10 km/h, and the travel time from Tokyo to Osaka is shortened from 6 hours and 30 minutes to 3 hours. This standard gauge electrified double-track railway, which is specially used for passenger transport, represents the world-class high-speed railway technology level at that time, and marks that the world's high-speed railway has entered the commercial operation stage from the experimental stage, with a maximum speed of 300 km/h. I hope my answer can help you. I hope it can be adopted. Thank you.
