If the UP had trackage rights with the MP, it would have been in places
like Omaha, St Joseph, Topeka, Salina, or Lincoln, which were locations
served by both roads. If there were no trackage rights, then they
most probably had interchanges there, where you could expect to see
power from both roads side by side.
In Kansas City and Omaha there presumably would have a been a belt line
or terminal road that both UP and MP had connections with, another place
where their power would be seen together.
As for the UP and WP, they both served Salt Lake City, and Wells in
Nevada, so perhaps they interchanged or had trackage rights in these
According to the 1956 "Handbook of American Railroads" published by
Simmons-Boardman, the MP was fully dieselised before the UP, so your
scenario as outlined above is possible.
