Yes this, and also, it's such a pleasure to just cook food at home or visit the supermarket and meander over to the train station and eat it on the journey. No restrictions on liquids/gels, and you aren't restricted to expensive crappy airport fast food.

Restrooms on Amtrak don't make you deaf. No stupid food carts blocking the way to the restroom. Even on parts of the world that have food service on trains, the carts don't block people from walking past them.

You can walk the entire length of the train whenever you feel like for exercise.

Turbulence is not a thing on trains, and there's much more space to get from the window seat to the aisle without needing to crawl over a stranger's lap.

Also, there's scenery almost the whole way.
