There is a need for increased geographical coverage in the right corridors. Many corridors with high population density are just not covered.

As bad as the passenger rail situation is in the US, I can totally understand how it got this way compared to other countries from a pure geographic point of view.

The US landscape is ideal for freight trains and not quite as ideal for passenger trains.

If you look at countries like Japan, the geography makes a perfect condition for passenger trains to be most ideal. Railroad as a shipping method for goods doesn't make a lot of sense, you can just put goods on ships that travel along the coasts and for shorter journeys trucks make more sense.

Or look at China: massively higher population, and their population is much more concentrated in the East of the country than the US with its split up coastal populations. Maybe we could say that a high speed train between Indianapolis and Cleveland would be nice, but there isn't even a single direct commercial direct flight between those destinations, so how will anyone fill up a train? China's huge population makes it an extremely ideal high speed rail use case.

But in the US, putting goods on a train from Chicago to LA makes way more sense than any sort of truck or ship situation. And even a high speed train on that route wouldn't make a whole lot of sense compared to a flight.

But there's definitely room to improve geographical coverage in specific corridors where that expansion would have great positive impact.

How does the geographic context explain how the US was (apparently) an excellent fit for passenger rail until the 1920s-1930s, but not anymore?

I don't think geography is the explanation. US geography is great for passenger rail. Japanese geography is terrible for it (too many mountains). In my opinion Japan's passenger rail situation today would be no different than the US if American rail companies had managed Japanese rail lines throughout the 20th century.

It's nice to imagine that geography is the reason, and so everything is as it should be, this was the fated result. But that's simply not the case.

Of course, rail is not a good fit for a weekend getaway from LA to New York. Even in Japan, where you can ride the bullet train all the way from Kyushu to Hokkaido, almost anyone would book a flight for that unless they really hated flying. But that doesn't mean that rail isn't well suited to American geography.

    > How does the geographic context explain how the US was (apparently) an excellent fit for passenger rail until the 1920s-1930s, but not anymore?
Simple answer: Cars and aeroplanes and gov't money for both, and lack of gov't money for passenger trains.

    > Even in Japan, where you can ride the bullet train all the way from Kyushu to Hokkaido, almost anyone would book a flight for that unless they really hated flying.
To be clear, the purpose of a bullet train between Kyushu and Hokkaido isn't to serve end to end. Rather, it is to serve region to region: Kyushu to Osaka/Kyoto, then Osaka/Kyoto to Nagoya, then Nagoya to Tokyo, and Tokyo to... Sendai(?). Honestly, I don't know why Japan is wasting money to build the bullet train to Sapporo, Hokkaido. It will never get enough passengers to make economic sense. After 800-900km of distance, it hardly makes sense to ride a bullet train. Get on a short flight instead. (Tangent: We really need electric aeroplanes to service these 90 minute routes in most countries.)

     > Simple answer: Cars and aeroplanes and gov't money for both, and lack of gov't money for passenger trains.

That has nothing to do with geography and everything to do with politics.

    > How does the geographic context explain
Let me summarise further: It does not. That was the point of my answer.

Exactly! That's exactly my point. That is why the geography and the size of the contentinent are mostly irrelevant, and trains don't have to be competitive with flights for trips between terminus stations, because most travel takes place between stations a shorter distance along the lines.

Planes did not exists.

Most of the railway trips people were taking would be fairly short distance trips you'd now hop in a car for, not a plane. Inter-urban transit, not trans-continental. You can look at old railway connectivity maps of the US to see the kind of station density available along the lines. This is why the size of the US continent is not a really good explanation. It's like saying "Europe is too big for trains, which is why nobody rides trains in the Netherlands". You don't take a plane from Amsterdam to Rotterdam, and you wouldn't have taken a plane to get from Boston to Providence either. Trains also can serve small towns that airplanes don't, because you don't stop a plane at every town along the way between city centers. In fact, many towns just sprang up around train stations.

> In fact, many towns just sprang up around train stations.

And this is how the Japanese system works so well. The trains don't make money, but the massive improvements to land value near stations does and the train companies own that land.

They get to make money, society gets the personal and economic benefits of a functional public transit system.

Passenger trains on their own fundamentally do not make money for the operators in most cases, except perhaps specialty routes like airports: the value is distributed into society, but doesn't all come back as ticket prices. So any system where a train company is just a train company will either need heavy subsidy or will slowly wither away under "efficiency" drives.

What they do have is a huge pile of capital intensive resources that are juicy targets for vampiric extraction and captive markets that are slow to extract themselves when exploited (and slow to come back).

Long distance (200-800km) passenger rail operators do make money, as long as the infrastructure is at least partially publicly financed.

Which is also true for anything happening on roads.

Well, quite. A fully ticket-funded passenger rail system is a rare, rare thing. There are simply better ways to make money than going solo on building and running a railway and not either diversifying or getting state support.

Yes, it's true for roads, but no-one expects roads to all turn a profit in the way that rail lines have to. Even for place with road use fees for motorways, most people can access the road system for rather less than the cost to construct and maintain it.

Unprofitable roads don't get closed very often.

    > The trains don't make money
This is untrue. From here: https://en.wikipedia.org/wiki/Farebox_recovery_ratio ... look at all the entries in Japan where ratio >= 100%. It is a lot. This one is bonkers to me (JR Central Rail: 245.95%), but easily explained by owning and operating one of the busiest bullet train routes in the world between Tokyo and Osaka.

And, this does not include all of the (profitable) real estate projects these companies use to further increase ridership!

Well, I stand corrected!

However, it may not include the real estate income, but it does include the income from extra ridership created by the real estate being near the station.

It's true, the bullet train prints money for JR. But there are also many train companies that are only profitable because of their real estate holdings around the lines, especially smaller private companies like Tokyu.

    > the bullet train prints money for JR
The bullet train in Japan only "prints money" for one JR company: JR Central, thanks to the busiest(?) bullet train route in the world: Tokyo to Osaka. Most other bullet train lines in Japan are break-even or loss making, but supported by the central gov't (for social policy).

    > only profitable because of their real estate holdings around the lines
Again about Tokyu: This is untrue. I could only find stats from 2005, but all train lines in the Tokyo metropolitan area (including Yokohama) have improved farebox recovery ratios in the last 20 years.

Here: https://www.lincolninst.edu/app/uploads/2024/04/2198_1524_LP...

Page 296: Farebox recovery (%), 2005 125.3 (Tokyu Corporation’s entire network)

After the opening of the last Tokyo Metro line (Fukutoshin) -- with direct connection to Tokyu Toyoko line (Shibuya to Yokohama), the farebox recovery is surely much higher. I guess over 150%, but probably closer to 175%. The trains are jammed 8+ hours per day. This means that, excluding real estate development, the Tokyu train lines are profitable by themselves.

    > especially smaller private companies like Tokyu.
About Tokyu: "[S]maller"? Absolutely not. It is surely one of the top 5 largest private rail companies in Japan by revenue/profits. They are huge in the Tokyo area.
