As I go through this build, if you have questions about signaling show me a picture of what you got that don't work. I've been at this for awhile and can move a ton of trains anywhere on my network. All 77 of them units ended up in Green Bay, WI at two different portals this morning after traveling 1,000's of miles combined to get there. Intersections, Junctions and Interchanges all need proper AI signaling to guide them through correctly. When you get that right this is just a fun game to watch.
