Furthermore, the trackside equipment, depots and other railroad structures will have both SF and SP flavour. I am beginning to like what I am modelling now, even more.
Sometime back, I was reading about Class 1 railroads and found David Hall's YouTube on How The West Was Lost. It was about the merger of railroads into UP and BNSF. I dugged further and came out with these two maps.
I have the above maps in PDF version. Email me if you want a copy as I can't uploaded into this blog.
I know there are other railroads I have not traced back or those taken over by Canadian Pacific (CP) and Canadian National (CN). I will do more once I have the free time.
