OK, this looks like it’ll be fun (I’m sharing your pain/ boredom, too !), so here’s a partial response and submission:
(1) CREATE - Agree !
(2) BNSF Transcon - well underway, almost done, only 3 short segments to go, so we need to find something else;
(3) UP’s Sunset - essentially ditto;
(4) NEC - Agree ! If this doesn’t already include a new set of tunnels under the Hudson (North) River, then it should, because they are absolutley at capacity (19 to 22 trains per peak hour, I believe), although this could be a separate project all by itself. See also (A) below;
(5) NS - don’t know enough about it to say, but it seems awful local = I haven’t heard about this before.
Here’s some other contenders, IMHO, in no particular order:
(A) New or upgraded freight main(s) parallel to and just inside (west) of the NEC, from Harrisburg, PA south to Miami, or at least as far as Jacksonville (FEC can take it from there). NS has been working on its Shenandoah Valley line, so that’s a start, but it needs to continue further south. The CSX lines are near or at capacity from Washington, D.C. on south - just look at the Amtrak delays;
(B) New or upgraded high-speed passenger main - including electrification - to extend the NEC from Richmond south to Miami/ Jacksonville, including to the North Carolina system. Again, CSX is at capacity - look at the Amtrak delays, and TGV-class trains shouldn’t be on the same tracks with freight anyway;
(C) Upgrade the ex-NYC “Water Level Route” all the way from NYC to Chicago for high-speed passenger main - including electrification, to connect those 2 hubs and the many cities along the way. Six to 8 hours ought to be the goal - roughly competitive with the airlines if travel to airports and check-in
