The Acela from NYC to Philly is 67 minutes over a distance that is almost exactly 100 miles.

That's about a 90 mph average.

that would be good enough for me...Amtrak has enough wrecks as it is...and BTW when we used to take the train from NYC to Baltimore it was packed with riders....I don’t think stepping it up to 150 mph would sell any more seats.
