I just spotted that in the next to last photo, it appears to show a B unit that is lettered “Union Pacific” and is numbered “500” which you can see if you click on that picture to see it enlarged:
This doesn’t look exactly like any UP engine I know of, but the maker was obviously trying to model something - maybe this was a concept train that was never built for service? While I’ll defer to others who think that the build quality of the set isn’t good, I AM NOT SO SURE ABOUT THAT. Someone went to a lot of trouble to put on all that gold fluting and add ventilation screens and roof details.
A little research shows that the UP 500 series locomotives were designated F9s and had a variety of car bodies. This doesn’t look similar but maybe it’s a lead. Anyway, this model definitely belongs in a museum!
