The consist was Amtrak 145, 822, 204, and 130.
Today, I caught Amtrak #2, the Sunset Limited, in Eastgate, TX. What was so special about this train was that the president was on it. There were five executive cars on the end, which you can see in the video I post below. On top of that, the train was led by 4 engines, including the two Phase 3 heritage units!
