There was a thread for the consist used to carry George Bush when he passed away. If it is doable, I am thinking this thread or another will grow rapidly. From what I can see in the videos today it was the Big Boy, followed by a black fuel oil tender followed by a second UP yellow tender (water?), followed by the 844 steam loco, followed by two of the same combo of tenders, followed by a diesel loco, a baggage car, and several passenger cars. Everything is probably already out there, it just may need some cloning and reskinning to make the exact consist.
