Ok, so much to cover in one post here.
The Cardinal requires two trainsets one for each direction, not one trainset.
Next last that I knew; each Superliner consist had 1 sleeper, 1 diner, 1 sightseer lounge and 2 to 3 coaches depending on the time of year. It did not have a trans-dorm, which made it rather cool since I could look out the upper level door and see right over the engines. It was almost like having a dome, and it was the first time I could see all the upcoming signals.
As for the crew of the Capital, I think that they are based out of Chicago, but I could be wrong.
Finally when I was up at Albany last weekend, the 449 came in with a Horizon coach in the consist.
