It's possible other corridors could be identified that could run something like that, though it probably needs to be about 800-900 miles to make it "worth" it time wise - shorter and it's simpler to just drive.
It’s mostly the Northeast Corridor from Boston to DC where Amtrak makes the majority of its profits though—which it then mostly loses in the rest of the country.
The auto train to Florida is sort of a special case. That’s not people traveling for a long weekend or even a week. It’s historically been people going south for the winter. Not sure it’s profitable though don’t see recent numbers.
If they really run that train every single day year round, and it almost always sells out, it can't just be people going south and back, or the winter trains would be empty.
I think it's just a common trip and the train is cheap/convenient enough.
I stand corrected. I thought it was a less frequent thing. Assume a lot of families do the theme parks that you really need a car for but they don’t want to do the long drive from the mid-Atlantic. Don’t know if it makes money though.
