Getting the long distance trains to twice a day should be a goal along with getting funding for state and interstate corridor services. OTP is pretty much a given. Pretty much any route with a 24+ hour run time is going to spend half it's run while it's dark. And it's not like every where that currently has service at dark o'clock is a small town. As was pointed out, Salt Lake City suffers from poor timing, so does the Bay Area with the Starlight, Charlotte NC would also have a half way decent overnight connection to New York if it's Silver had a second run 12 hours later.
I'd love to see 2 scheduled trains on each Amtrak route, but to me not holding my breath that'll occur as soon as it should IMO. It should occur, if you ask me. Ditto with regional Amtrak routes with only 1 scheduled train in each direction(and 2 overall) a day. I.e. Pere Marquette to Grand Rapids, Blue Water to Port Huron, MI, Heartland Flyer between OKC-Fort Worth, and of course any lines through New Hampshire and Vermont that only have one scheduled train in each direction(2 overall) a day.
Of course at the same time, I'd like to see eliminated Amtrak long distance routes have service once again. I.e. Pioneer through places like Boise, Desert Wind through Las Vegas and etc(not sure why at the bare minimum there isn't a Vegas-LA corridor train already), have some sort of train run once again through southern Wyoming(whether that's a new Pioneer train covering southern Wyoming along I-80, or another train), a restored North Coast Hiawatha(through Missoula, Bozeman, Billings, Bismarck, etc), a restored Floridan(through Louisville, Nashville, Birmingham, Dothan, Jacksonville, etc), a restored National Limited(through KC, StL, Indy, Dayton, Columbus, Wheeling, Pittsburgh, and east to NYC like the original one), to name examples. I do wonder if the tracks remain for each of those former long distance routes for such train service to resume, along with of course that negotiations would have to occur with freight railroads for service to begin again.
You're right about the Bay Area and Sacramento with having late at night times(at least going northbound, and Sacramento's southbound time is kinda early at 6:35am too, don't get me started on the places north of there like Chico, Redding, etc), with Coast Starlight. I weirdly forgot to mention the Coast Starlight late times, but correct about those!
