Ok. I know the standard Capitol Limited consist is 3 coach, 1 lounge, 1 diner, 3 sleepers. Assuming they had the cars to do it (since I know such is an endless issue for Amtrak), how hard would it be for them to slap an extra sleeper and coach car on the train around Christmas? I'm especially thinking of the sleepers, which tend to sell out a bit earlier. I know at least part of the issue there is diner capacity (though on my CL, they didn't seem to be using the full diner) as such meals are guaranteed, but how hard would it be to stick 2-3 extra cars on the consist during the "blackout" periods?
