Living somewhere with a good train network, I agree with this entirely. There is no better way to do long distance travel than a train. Infinitely more comfortable than air travel with far less hoops to jump through. I can show up ten minutes before my train leaves, grab some good food for the trip. Have way more space than you would on a plane without spending ridiculous sums of money.

I basically always take a train for domestic travel. Very often it ends up being faster than air travel, with less time spent before departure/arrival and train stations being more centrally located within the city.
