Keep in mind the Missouri Pacific was absorbed into the Union Pacific around 1980-1982. And also keep in mind the BN was created by merger around 1970. That pretty much limits your era to the 1970s. As for locales where they crossed - maybe in Missouri, Oklahoma, or Nebraska. As mentioned, look for route maps online. Grain elevators would be a likely industry in any of the three states I just mentioned.
