Indeed. You can always transport booze on Amtrak, and since they’re in a sleeper, can consume it onboard (in their room) as well. The only restriction is that non-sleeper passengers can not consume their own stock onboard.
When my wife and I travel anywhere, we always make it a point to try to visit at least one local winery/wine store to sample the tastes of the region. We always intend to bring several bottles home, but it's rare that our entire stash makes it. Something about a relaxing evening on a train (in a roomette/bedroom of course) that just makes you want to open a bottle. We now include a pair of polycarbonate wine glasses in our train case, since we know the temptation will usually win out.
Don't forget that the sleeping car attendant will be in your room to set up the beds at night and put them away in the morning so you will need to store the bottles of wine in a spot where they would not be easily knocked over and broken.
Now that I feel we'll be OK bringing wine on the train with us.....We actually have a padded carrier that holds 12 bottles of wine; it has wheels and looks like a normal weekender. I hope to use it for one of our carryon's, putting each bottle of wine in a large ziplock bag and the electronics in the other carryon.
The real question is how do you keep yourself from ruining that bubble wrap by happily popping all the bubbles?
Two words I agree with: Bubble Wrap.
Depends. The tiny bubbles probably won't protect a glass bottle well. It's harder to find the bigger ones, but I've had stuff packed in 1/2" wide bubble wrap before. However, there are special cushion wrap protectors designed for wine/liquor bottles.
