You cannot share track. Take a look at the ICE lines in Germany. The high speed sections are dedicated, with no level crossings and fencing the entire way to eliminate collision risk. When a train is going 400kph, you can’t share track. |

Correct, you would be traveling at normal train speed on shared track. This is workable in some systems because you can build cheap (relatively) rural segments of high speed rail without needing new right of way through urban areas. Obviously wouldn't work everywhere, and maybe it's not the right solution here. But it is done some places, and places like California are considering building new blended systems [1.
