Utah, with a total area of some 84,899 sq. miles, is nearly 2x larger when compared to Ohio at 44,825 sq. mi.
Ohio has a population of about 11.6 million (7th nationally) to Utah's 3.1 million (13th nationally).
I'm not talking about the state, I am just talking about Salt Lake City.
You said:
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.
KmH's point was that the entire state of Utah has a quarter the population of Ohio. So it helps a hell of a lot more people to add a daytime Ohio train than to add a daytime SLC train.
Another thing to note is that Salt Lake City has a significantly smaller population than that of Toledo, Cleveland, or Cincinnati:
- SLC – 193,744
- Toledo – 278,508
- Cleveland – 385,809
- Cincinatti – 298,800
So if you compare the population of Utah to that of Ohio, Ohio wins. If you compare the population of SLC to that of the major Ohio cities, Ohio wins.
