Interesting - I said 40+ hrs as well, but either coach or sleeper is OK for me (of course I'd prefer sleeper, but it often ends up being cost-prohibitive when I want to travel - as such I usually end up just doing it on short trips where I'm returning to work on the day of the arrival like the LSL westbound). I did a loop trip much like yours on the Texas Eagle, though it involved 3 different routes - I took the Cardinal to DC, switched to the #66 Northeast Regional, and then caught the Lake Shore Limited from BOS (coach on the Card, business class on the Regional, and sleeper on the LSL). I'd say what you are doing isn't quite the same as a single 60-hr trip (more like a connecting train) but is close. Nice idea for an AGR award, though - though you could actually go as far as ELP in one zone (though you would probably have to stay over to return).
