Interesting thread, though part of me wants to question your use of "Mainline" at times. To me a Mainline is any track laid to get from Point A to B with at least a preference for keep it clear for regular traffic..... EK3 has a Mainline for instance, you can just see most of the ends of it.....
It kind of feels like you're looking for essentially unadulterated PTP (Point to Point) Train Driving (For lack of a better description?)? Presumably with hours worth of Drive time or something?
I would agree that unfortunately there isn't much more then what you've listed at this point currently available, to the best of my knowledge certainly.....
As for East Coast stuff, outside of the NEC attempts made by a few people currently available I can't think of any seriously good eastern Seaboard routes that would qualify for what you're looking for. The East Coast, as I understand it, is hard because of the integration of human Communities within the landscape. The reason where theres lots of either Super Barren Routes or Super Forested Routes is because its always been far easier to make 20 miles of repetitive natural scenery then it has been to make 2 miles of human scenery that doesn't make one cringe (Call it our over-familiarity with ourselves and our leavings). Not that it can't be done, but remember to do a mega route its gonna have to include cities, so once you do those 2 miles, you get to do another 2 miles, and another 2 miles.... Pretty soon you're thinking fondly of that 60 Miles of Scrubland, or Forest, or Desert, you just did to get out here to this cotton-pickin' city.....
I'll keep an eye on this thread anyway though. I did learn of a couple routes I either hadn't, or had forgotten about at least.
