Nah, the US let their rail system go to crap I could theoretically catch one from Chicago to Pittsburg...but then I'd have to drive 3 hours to Chicago, pay to park there for the duration (and pray it isn|t stolen and/or vandalized), then catch another train from Pittsburg to a stop another 4-hour drive from my dad's house, and either rent a car or ask him to drive 8 hours to pick me up. Either way, I pay out the butt for a rental car, or I'm stuck at his house.
Oh, and I would then have to also pay to board my dog because she wouldn't be allowed on the train. Driving 14 hours is nothing compared to that nightmare. Both less hassle and far less expensive. And my dog would be sad and lonely for weeks? Never.
Seriously, if you get really into a good audiobook, it isn't that bad. Just start early, drink lots of coffee, and don't start checking the time. Worry about the book instead, and it flies by.
