All of 2023 isn't necessarily going to be this. Amtrak's hiring, and that's taking time. They'll be able to repair more cars and bring them back into service, restore traditional dining, etc. when they've got more workers. NARP/RPA seems to be keeping on top of whether, once Amtrak is able, it's making improvements or not.
Everyone's short of workers nowadays and showing it in their operating hours or levels of service, but nobody thinks Starbucks or McDonald's is trying to drive away customers. Not that you (Railspike) said that, but the idea that Amtrak is trying to drive away passengers keeps popping up here, and it's a bit wearying.
Amtrak's clearly pushing for restoration of Gulf Coast service to Mobile and was willing to take on the host railroad and call out its BS to do it. While it's corridor service and not long-distance, Amtrak itself came up with the idea for the Amtrak Connects corridor development program -- they asked Congress to fund the program, not waiting for Congress to tell them what to do -- and seems to be taking it seriously. While it's state-driven, the second train Chicago-St. Paul may well be coming in 2023.
And while it's also state-driven, the Venture cars coming online in the Midwest and California will
(1) bring a nicer and more modern travel experience to some busy corridors with millions of passengers annually, and
(2) free up Horizon and Amfleet cars to lengthen and add trains elsewhere in the system, so that they don't need to wait for the Airos (also a nicer and more modern travel experience) to come into service in a couple of years.
All that sounds like grounds for cautious optimism on the non-NEC corridor front even if things look less than favorable right now.
As to the long-distance trains, Amtrak did restore traditional dining to most Western trains, which some skeptics here insisted they'd never do. (Also, not everyone thinks the misnamed flexible dining is "garbage" just because some loudly and repeatedly insist it is. One man's vote, but I ate it on an LSL round-trip in April and thought it OK, not great but also not bad.) And while Amtrak may not be too far along in their plan to acquire new long-distance cars, Amtrak has a plan to do so, which tends to contradict the skeptics who insist Amtrak is trying to get rid of the long-distance trains.
