Depends on how you define long distance travel. I would say anything over about 500 miles would be better done by air.
But back to the OP. The
practical limit on "high speed" seems to be somewhere below 300 kph, or about 180 mph.
I used to fly from Dayton to Chicago to a place on N. Michigan Avenue a couple of times a year. Air time was less than an hour, but travel time was 4-5 hours or more depending on the time of day. I could drive there in 6 hours on a good day, 7 if traffic was bad. I don't think a train - even a high speed train - would save any time over air and maybe would take longer than driving, but it would be a lot more relaxing than driving or flying.
