> Guess what there is something in between the Nevada desert and the North East corridor.

Is there though? Here are the cities with at least 500,000 population on the line between Chicago and Sacramento: Denver. That's it. Omaha has just under 500,000 people. It's over 2000 miles of farmland and desert.

> And Amtrak operates in several places where there is very little other options for people, so operating at a loss at time is perfectly reasonable for a public service.

The people who live in western states have cars. Amtrak is useless because it goes to Chicago but not to the grocery store, which is why they have cars, but their cars can go to Chicago too. Or to the airport, because Chicago is a thousand miles from them.

> And the point about Metro North, guess what if the freight railroad owned all those tracks then that would be possible either.

Sure it would, because you could build entirely parallel tracks there exclusively for passenger rail and it would still be profitable because it's a high population density area where passenger rail actually makes sense.

I was speaking as 'in between in terms of population density' not literally in between geographically.

> The people who live in western states have cars.

They have cars because they have to have cars because there is no alternative. That's the whole point, you need public transit so people don't need to own cars.

And guess what, the poor don't actually have to have cars. And guess what, cars still require lots of government infrastructure that's really costly.

A city to city transit system needs to be integrated with a regional and a local transit system.

I live in a city with 70k people and there is regular service to many villages and cities with 30k people or less.

I recommend you read the blog pedestrianobservations.com, he has a lot of knowledge about transport systems and cost. You can read about his recommendations for US travel including high speed rail there:

Passenger rail even in population dense regions is hard to make profitable, specially if you want to have high frequency and allow service from early morning to late night. If you had to build new infrastructure form the ground up its hard to justify.

Thinking about profitability first is just a generally bad idea when talking about infrastructure.

But that's the problem really. Once you get away from the coasts the population density really does fall off a cliff.

Nobody is building public transit in a farm town. The people there don't even live in the town, they live on their farms and go into the town in their trucks to buy groceries and supplies.

> And guess what, the poor don't actually have to have cars.

If they live in farm country they do.

> And guess what, cars still require lots of government infrastructure that's really costly.

Roads in rural areas are a sunk cost. You need the roads for trucks and there is no incremental cost to using them for cars because there isn't going to be enough traffic to cause congestion regardless.

> A city to city transit system needs to be integrated with a regional and a local transit system.

A city to city transit system is going to have one or two train stops in each city. The city government knows where they are.

> I live in a city with 70k people and there is regular service to many villages and cities with 30k people or less.

How close together are these cities? 30 miles or 300?

> You can read about his recommendations for US travel including high speed rail there:

That map is kind of silly. If you're going to build high speed rail in the eastern US you build it parallel to I-95 from Boston to Miami and I-80 from New York to Chicago, and then they intersect in New York, the largest metro area in the US. Why does he have a separate line going through Springfield and Buffalo? And he has lines intersect in Albany?

Then he's trying to connect a bunch of mid-sized cities in the midwest with non-functional mass transit systems because they're too spread out, where you would get off the train and have nowhere to go.

It's trying to be clever and make it complicated. Two lines parallel to the two highways and you get 90% of the benefit for 30% of the cost.

(It's also adorable that he wants to put high speed rail through Detroit. Come on, guys, think about local culture for a second when you're evaluating prospective adoption.)

And this is kind of my point. You have some sensible kernel of an idea, like hey let's do high speed rail between the biggest cities on the East Coast, and then it turns into this over-complicated boondoggle.

> Passenger rail even in population dense regions is hard to make profitable, specially if you want to have high frequency and allow service from early morning to late night. If you had to build new infrastructure form the ground up its hard to justify.

Offering more frequent service for longer hours makes it easier to build new infrastructure because you have more trains to amortize it over.

You can make something arbitrarily unprofitable by adding unprofitable lines until they consume all of the money from the profitable ones. That's not the same thing as being hard to make profitable.

> Thinking about profitability first is just a generally bad idea when talking about infrastructure.

It's not so much profitability as cost effectiveness. Spending money to build or operate a rail line to the middle of nowhere that nobody is going to use is wasteful and unnecessary. But Amtrak does this.

There are literally many multi million and multi-100k cities away from the coast.

And trains don't need to be connected, its totally reasonable to have train network that mostly covers one area.

> If they live in farm country they do.

But most people don't actually live in 'farm country'. So its completely irrelevant.

I'm gone go with the guy who is a professional transit expert over your opinion.

They're not near each other.

If you draw a 100 mile radius around New York City, inside it you find Yonkers, Stamford, Bridgeport, New Haven, Waterbury, Newark, Jersey City, Paterson, Elizabeth, Edison, Woodbridge, Lakewood, Allentown and Philadelphia. Each of which is a city of at least 100k people. Philadelphia is 1.5M.

If you draw a 100 mile radius around St. Louis, which he's got on his map, you've got... Springfield, IL just at the far edge of the radius with just over 100k people, and that's it.

There is one midwestern US city with a population in the multi-millions, it's Chicago, it's the one I suggested as the terminus of the rail line, and it's still on the coast... of the Great Lakes.

> And trains don't need to be connected, its totally reasonable to have train network that mostly covers one area.

Oh sure, high speed rail along the California coast could make sense even if it's only in California. Though then it's only in California and doesn't require any federal involvement.

High speed rail in Indianapolis though?

> But most people don't actually live in 'farm country'. So its completely irrelevant.

Most of the central United States by area is farm country. It's the thing you have to traverse, laying hundreds or thousands of miles of tracks through, if you want to try to connect a handful of medium-sized midwestern cities.

The fact that not a lot of people live there (i.e. it has a low population density) is a big part of the problem.

> I'm gone go with the guy who is a professional transit expert over your opinion.

Your transit expert is a mathematician with a Wordpress site. Math is neat, but it's also the thing that leads to hubris when the equations are missing a variable you were ignoring because it's the same in coastal cities all over but not in midwestern states where the cities are both smaller and farther apart and the largest employers are the automakers whose employees see your transit solution as a threat to their livelihood and are not going to use it.

It's a classic central planning fallacy. You have some numbers in a spreadsheet but haven't gone to the place you're drawing lines over on a map.
