I'm confused about why everyone is obsessed about daytime Ohio trains but no one cares that Salt Lake City is in the graveyard shift. If another Chicago-Denver train is established, it could overnight through the mountains and reach Salt Lake City during the day.
Which Amtrak train's disappearance would cause the least amount of unhappy people? This would be route that has very little support from, well, anyone. I propose the Sunset Limited. Do any of the states along the route actually care about it?
As you know, Ohio should get a daytime train. Cleveland has two trains, but both stop in the middle of the night. The Lake Shore limited should be retimed to give Cleveland a daytime train, as most of the route is served by other trains.
