The possible comparison is the Boston–Washington corridor but that’s about it.
Actually, there are several other corridors besides Boston/Washington where there is sufficient population density to support high-speed rail.
You have to understand that the United States is a very low density country. If we had the same population per square mile as the United Kingdom, we’d have over 1 billion people.
So we’re several times larger then most industrialized countries and we’re several times not as dense. So not only do we have to build longer and more tracks (or wire for high speed internet) but they’ll only accessible (and paid for) a much smaller percent of the population then Japan or France. The possible comparison is the Boston–Washington corridor but that’s about it. (And guess where is one of the few places where Amtrak is profitable?)
