Do you mean the internal layout/configuration of the cars, or where each car is in the consist?For internal layouts, and information about the Texas Eagle, have a look at http://www.texaseagle.com/ . The Capitol Limited uses the same type of equipment.
As for consist, it is usually as follows:
Engine(s) - Baggage - Transition sleeper (crew) - sleeper(s) - diner - lounge - coach(es). Sometimes the coaches are behind the baggage car instead. The Texas Eagle has a slightly different configuration on different days.
