Whether on paid business travel or on vacation, my time is worth $50/hr. Only on short trips of <360 miles is a train not going to make my trip vastly more expensive.
Say someone is making $25/hr, an additional 6hrs on the train equals $150. And the last time I checked, AMTRAK was already more expensive than flying.
Also, driving inside of 250 miles is almost always faster than total trip time of flying, from home to final destination.
Finally, with relatively little additional cost, current trains could be running at 100mph over most lines, but they don’t because it would be more expensive.
“And the last time I checked, AMTRAK was already more expensive than flying.”
Wow, it’s slower, more expensive, and more often than not hopelessly behind schedule*. What’s not to like?
*In Amtrak’s defense this is because it uses the trackage of private railroads, who have no compunctions about holding up an Amtrak train to let one of their freighters through.
