Trains generally only work in very limited markets . . . as a practical alternative to airline travel in highly-congested “mega-regions” where cities are close enough together that their overlapping exurban areas (Boston-NYC-Washington, for example) make auto travel difficult and time-consuming.

The higher the density, to say nothing of natural contours (ie river valleys), the better the location for rail. After spending two years in Seattle, I can honestly say that rail would work there, as the metro area lies in a narrow valley with natural barriers that prevent further sprawl (the Sound, the Cascades, and the Olympics).

I don't see rail working in Houston, let alone Oklahoma City.

I looked at taking a train from Jackson Michigan to Toronto.

I could catch the train in Jackson, then ride it 200 miles west to Chicago, then 550 miles east to buffalo NY where I would get off the train, cross the border and get on another train for the ride to Toronto.

I drove by way of Windsor.
