I suppose you have already entered your comment in the FRA LD Committee docket pointing this out? I have.
Yes I have. Mine was rectifying the sloppy Pittsburgh situation between the Pennsylvanian and Capitol Ltd with a neo-Three Rivers or Broadway Limited since Airo trainsets will be incompatible with thru car arrangements.
But most other advocates seem pre-occupied with Daily Cardinal and Lake Shore Rail Alliance, which ignore midwest and Chicago access from New Jersey, eastern, and central Pennsylvania.
I remember a hearing with Anderson back around that time where he was talking about this. Unlike some I don't think their intention was to discontinue or dismantle the entire network of all 15 long distance routes 100% though I think as hinted the vision was altering portions of the network to mostly shorter daytime running segments and retaining a couple of the more scenic long distance trains intact as more of a premium experiential type tourist trains possibly influenced by services like the Canadian (they basically indicated the Coast Starlight, California Zephyr, and Empire Builder as the services they would keep as is as tourist trains) - a network setup I think most of us would have opposed pretty strongly.
Anderson was fool enough to spill his cookies and blather that he wished to have a network of only 5 - 10 long distance trains, so probably a Silver train and the Lake Shore Ltd to hold it together on top of the 3 western trains. He did lease a bunch of Superliners to California, so sure the Chief would come off.
He was a very confused, ignorant, and unteachable little man, how he thought he could emulate VIA Rail's Canadian, Ocean, and Skeena while coach passengers are restricted to filling station food in the cafe car (which most still are) and flexible dining slop served in plastic in the so-called diner.
