Although I do not have pictures to share with you, I can tell you this:
We took the auto train weeks after 9/11 because we were too afraid to fly. We were really nervous about the auto train, but we were very pleasantly surprised! .
The coach areas of the auto train were very clean. The seats are very spacious, too. Although they do not recline flat, I was able to sleep pretty soundly. Here's a hint: because the seats in the auto train are in sets of two, many people grab a set of empty seats at night & make it into a bed. We did this on the way home and it was much more comfortable. Also, bring a pillow and a blanket because the ones that Amtrak gives you are very small.
The dinners are surprisingly good, too. I think I had a grilled chicken dinner w/ veggies. They also give you complimentary wine with dinner.
There is a lounge car that serves many types of mixed drinks. There's also a few cars that show a first-run movie during your trip.
This year, we're taking the auto train again, but we opted for a sleeper compartment instead of going coach.
