I don't think that was the point he was making. I believe he was saying to gradually upgrade the "out of town" sections, and while you're doing that (he said 40 years?) run high speed trains the whole way. And when it hits an upgraded section you step on the gas.
My point was that it takes many, many years to get the entire length (500 miles or whatever) upgraded, which means that for the interim you might, for example, be running 90% of the distance low speed, and 10% high speed. Then in a few more years, it's 80-20%, and so on.
From a publicity aspect, that sucks. For many, many years (decades?) the public sees a "crippled" system that, from big city to big city, is not much better than the existing 11 hour trip.
