"Next post, I will go into more depth of the consists needed, the prototype cars, and models available, but I want to start with an overview of the issue."
We will hit the consists and talk a little bit about the prototype cars this post. I'm going to save the models for an additional post later on, as I want to take some pictures and make some other documentation available to cover that subject accurately. I've cover the locomotives in an additional post as they are owed an exclusive look, in my opinion.
Generally, you can count on the long distance trains to have a mix of sleepers, a kitchen/diner car, a baggage or two, then coaches and possibly a lounge/snack car.
You might see observation cars (either of the dome or blunt end variety), express cars, dorm cars (usually an older sleeper for the crew's use), and maybe some private varnish at the end.
The shorter distance trains (sometimes called regionals) normally will only have a couple of coaches, and a lounge/snack car. You might see an express car sometimes, and a couple of them have apparently had baggage cars, but normally they will be straight Amfleet cars.
Finding exact information about consists has been a bit tricky and to date, I have only been able to track down a few thanks to Jim Langston's Amtrak clinics. Here are a couple of consists from his clinics that would cover my modeled area:
These snapshots only cover the long distance trains; which makes some sense as Jim is out of the Jacksonville area (IIRC). As to try to find out what there was on the regional and other trains, you are forced to scour the net for pictures, turn up books related the subject area and connect with railfans who might have additional information.
