Thanks for posting. I had to look up Marion on a map. It is on the old SP line between Salem and Albany.

Do UP dispatchers refer to that as a north-south mainline? The old SP was dispatched strictly as an east-west railroad, which made things very confusing on some of the (geographic) north-south mainlines in California and Oregon. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to - An online railroad bookstore featuring a curated selection of new and used railroad books.
