Ricardo, can't you just go the Amtrak Website and email them your questions. Your questions don't have a lot of substance, and are getting repetititive.
You can also call
1-800-872-7245 which is the official number for Amtrak, and say "Agent" when Julie (the "lady" on the phone) tells you to.
Also, you should try going to
Railpictures.net and where it says "Select Railroad" choose Amtrak (or what ever other Railroad you may be interested about). Where it says "Enter Keywords..." type the train you want to see (like Palmetto, for example) this way you can actually see the train and answer your own question, rather than annoying (some of) us.
For example I did a search and found several pictures that answer your own question.

The second one with the baggage car in front is older than the others, but as you can see the consist varies.
Knowing you're going to ask it runs with 3 Coaches, 1 Business Class Car, and 1 Lounge Car.

So, you see Ricardo, if you do all of the things I told you to, you won't need to ask us questions.
