Congress will have to legislate the termination of this Balkanization of Amtrak service. Any route that goes 2 or more states should not be subject to the 750 mile artificial limit. That IMO was an effeort by certain POLs to limit Amtrak and travel demand.
They (Boardman, Lautenberg, Gardner as Hill staffer) came up 750 miles to draw a Sharpie line between the Carolinan (704) and Capitol Limited (780) and of course exempt the NEC spine (457).
Anderson/Gardner's/Coscia's "National Network 2" of 2018 would have slashed the LD network from 15 to 5 trains, kill or chop up into state supported corridors the rest. PRIIA-209 set the basis for that. The SW Chief Bus Bridge was the start of it. The Amtrak Board has yet to officially refute the plan, only exposed by a Trains-in-The-Valley FOIA request. Balkanization is what they wanted. That's why the Pennsylvanian will not hold so much as 15 minutes for a late Capitol Ltd - because Penn DOT wants an on-time departure, does not much care for the connecting revenue that the sloppy connection has done a pretty good job of killing since 2005 (thank you David Gunn).
I think it shoud be 105 miles to limit PRIAA-209 to quasi-commuter runs like Sacramento, Milwaukee, Harrisburg, Springfield, Greenfield.
Getting back to Ohio, Governor Kasich, a so-called moderate, complained 3C would be for "39 MPH trains", on a poorly designed timetable that Amtrak designed to fail, would someday have Ohio pay $10 million to subsidize, which is less than what Ohio pays to mow median grass in interstates, so he threw the money right back at Obama. I don't think Ohio politics are any more favorable now.
