As i understand things at a fairly high level, and particularly w/r/t the northeast corridor, high speed rail in the US has two interlinked technical facts about it that are hard to get over even if we can wave a magic policy wand and make governmental buy-in work several orders of magnitude better:

- It's not that "American rail construction is just bad. However, this is not because rail is bad; it’s because the United States is bad.". It's that american rail construction in the northeast is OLD, and we're hosed by the first adopter paradox.

- from this, it directly follows that upgrading the rail for high speed use is HARD, because the issue is at least in part down to rail line geometry. AIUI, a fundamental reason you can't go 95mph between Boston and New York is that the railroad tracks have curves in them whose radii have a maximum speed without risk of derailment that's quite low, and to resolve this problem you'd have to eminent domain swathes of, say, New Haven. There are other issues too, like local/freight/... sharing the same lines, but that's kind of saying the same thing twice: construction through densely populated Northeast Corridor cities is so impractical that it's hard to see how it could ever happen or be thought of as a particularly good thing if it did.

I really don't buy this oldness argument. We have to build new alignment you say? That makes it like greenfield elsewhere. Connecticut is dense you say? That's just much parts of Europe.

What that leaves your argument with is that existing rail only makes things harder because of a sunk cost facility. Let's improve our bean counting then.

Maybe America is one big sunk cost fallicy, being an older republic. Time for some creative destruction I guess.

those parts of Europe, let's not forget, were rather thoroughly flattened to a wet paste about 80 years ago, and were rebuilt with nice, straight, quick rail lines by people who knew how fast trains that weren't built in 1840 could go.

For the most part, the cities in France that could fairly be said to have been 'flattened' during WWII were in Normandy. Paris was scarcely touched. Yet they have a high-speed rail network covering the whole country. Spain was untouched by WWII, yet they have a high-speed rail network. The U.S. somehow managed to build an interstate highway system through every major city in the decades after WWII without being bombed flat. The WWII argument seems weak.

The U.S. has essentially stopped building urban interstates since the late 70's, when opposition from residents became too strong to ignore. I don't foresee this changing in the near future.

My understanding is that construction costs in Europe are rising as well due to (among other things) increased use of tunnels in urban area due to opposition from residents.

That is a ludicrous route for high speed rail.

I don't really know this area. Say you wanted to build an entirely new and mostly straight Stamford - Waterbury - Hartford - Providence alignment. Some of that would need to be in tunnel. But how much of that could you do on the surface without needing to demolish too many houses?

Re:Getting High-Speed Rail Wrong by jefftk on Thursday May 13, 2021 @02:19PM (#27145421)
That map is at least a little bit aspirational: it shows the Northeast Corridor extending north of Boston's South Station to North Station via "Central Station". While I would love it if we built https://en.wikipedia.org/wiki/North%E2%80%93South_Rail_Link it does not currently exist.
Re:Getting High-Speed Rail Wrong by tpmx on Thursday May 13, 2021 @02:49PM (#27145792)
The main impression it gave me (be sure to toggle to the satellite view - then you can also verify the existence of tracks) is how tricky it would be to build a reasonably straight railroad there while also connecting the population centers.

The route that the existing track takes is insanely suboptimal and seems so hard to fix considering the existing urban sprawl in the relevant areas.

Re:Getting High-Speed Rail Wrong by rustymonday on Thursday May 13, 2021 @04:52PM (#27147303)
It makes most sense to me for rails to be built in the interstate medians. You see this in Chicago, and could be done elsewhere relatively easily as its already government owned land. As a bonus, car commuters could see how much faster HSR might be than their normal commute.
Re:Getting High-Speed Rail Wrong by bobthepanda on Thursday May 13, 2021 @05:34PM (#27147771)
Interstate highways are designed for a speed limit of <100MPH and have the curves to show for it.

High speed rail goes well beyond that speed and needs much larger curves, at which point you're deviating enough from main roads you may as well just take a different path entirely.

Re:Getting High-Speed Rail Wrong by bluGill on Friday May 14, 2021 @09:21AM (#27153977)
Your not wrong, but not really right either. Interstate highways do allow tighter curves and do have them. However most of the interstate is straight or a gentle curve. Thus you can limit your land takings to near the curves and then rejoin the interstate. There is a good chance that the highway department will be interested in your new right of way to make the curve better too - a lot of interstates have curves that are too tight for highway use without slowing down. Many of the tight curves are also near places where you would want to slow down for a station anyway.

The above isn't a perfect answer to all situations, but it helps a lot.

Re:Getting High-Speed Rail Wrong by bobthepanda on Friday May 14, 2021 @11:26AM (#27155274)
Maybe in very flat areas where the interstate was preceded by nothing, but curves to avoid things in urban areas or for geographical reasons are more common. And HSR curves are gigantic; the Chinese build their HSR lines with curve radii of 4km. Texas uses a maximum of 1.4km curve radii and they have some of the fastest Interstates around.

The rail solution to that would probably be a tunnel. A tunnel is a cheaper affair with just two tracks than if it has to be wide enough for two tracks and six to eight highway lanes.

Re:Getting High-Speed Rail Wrong by bluGill on Friday May 14, 2021 @12:29PM (#27156125)
Urban areas are just a small minority of where the tracks need to go, as such if the train goes half the speed in the urban area we are still okay on overall trip time. In fact I suspect (read I don't know because it hasn't really been tried) that HSR should probably do a bunch of stops in the urban areas anyway so it won't get up to speed.
Re:Getting High-Speed Rail Wrong by bobthepanda on Friday May 14, 2021 @11:42PM (#27162132)
When I say "urban area" I mean the continuous built up urban area into the suburbs. American sprawl means that metropolitan areas are much further spread out than their European or Asian counterparts, to the point where most of Boston-Washington is sprawl and very little of it is farmlands.

In any case when you start building HSR it becomes progressively harder to eke out savings and the highest come from urban area speedups. Going from 50 to 100MPH cuts a lot more time than going from 150MPH to 200MPH. And the former simply doesn't work in the median of a highway.

Re:Getting High-Speed Rail Wrong by tpmx on Thursday May 13, 2021 @05:11PM (#27147520)
The interstate highway along that stretch (I-15) does not seem to have enough space in the middle for that, unfortunately.

How are you ever going to achieve high speed if you are stopping every 10 miles for another station? There appears to be 8 stations in Baltimore alone.
Re:Getting High-Speed Rail Wrong by tpmx on Thursday May 13, 2021 @04:55PM (#27147322)
There are four tracks - that enables the combination of a slow local stop-at-every-station service along with a fast feeder service.

But then the bizarre/historic track geometry ruins the fast service...

Re:Getting High-Speed Rail Wrong by lmm on Thursday May 13, 2021 @10:54PM (#27150163)
So the fast service shouldn't use that alignment. There must already be population centers that are skipped by the fast service - its tracks don't have to go through there either.
Re:Getting High-Speed Rail Wrong by bobthepanda on Friday May 14, 2021 @11:20AM (#27155208)
Today the fast services follow the same alignment.

Rerouting so far has been a headache; in New Haven-Boston where the tracks are so curvy new tracks have to be built, the FRA proposed going through entirely different population centers (the geography of the existing coast line is very challenging). This has resulted in an interesting fight where people want the train in their town, but also do not want the impact of newly constructed tracks through their town.

Re:Getting High-Speed Rail Wrong by cbm-vic-20 on Thursday May 13, 2021 @10:03PM (#27149819)
This map shows all the local stops for each city's commuter rail system. Intercity trains skip over many of these. The Acela leaves Boston, stops a the Route 128 suburban ring station (which has a large parking structure), and then hits 150mph on its way to Providence. Local MBTA service hits all of those intermediate stops.

Re:Getting High-Speed Rail Wrong by bobthepanda on Thursday May 13, 2021 @05:28PM (#27147698)
They accelerate reasonably quickly, but doing so any faster uses more energy and also starts impacting passenger comfort. People would like to have a cup of coffee on the table without hot liquid sloshing out onto their laps.
Re:Getting High-Speed Rail Wrong by machello13 on Thursday May 13, 2021 @05:41PM (#27147846)
They absolutely can. They're obviously limited by passenger comfort as the other commenter said, but the difference between an Acela and a Northeast Regional in acceleration speed is obvious.
Re:Getting High-Speed Rail Wrong by bluGill on Thursday May 13, 2021 @12:12PM (#27143841)
What is hard is nobody is willing to make and follow a long term plan. Amtrak has plans since the 1970s to fix those curves. Most of the places that would need to be bought have gone for sale since then - a bit of vision would mean that very little eminent domain would even be needed (not zero - there is always the one family that has lived in the same house for years). Also with the plan, you don't need to do it all at once - fix something every year.

Amtrak hasn't had the vision to stick with the plan. Instead we get a new plan every 10 years or so. Sure the new plan is arguably better, but the old plan complete would be better yet. The money spent making a new plan would fix one of the bad curves (only one though)

Re:Getting High-Speed Rail Wrong by acdha on Thursday May 13, 2021 @01:19PM (#27144692)
> Amtrak hasn't had the vision to stick with the plan.

I think this would be better stated as “funding” — it's not like nobody at Amtrak has failed to think about the hotspots for them, it's just that they are in the unfortunate position of being expected to service a lot of [now] marginal routes against both very well funded alternatives, but they have limited governmental support for the kind of major infrastructure changes they need to dramatically improve their offerings.

A completely private business could, for example, simply discontinue unprofitable lines or acquire long-term debt to fund a major capital investment but they were created specifically to avoid closing routes and debt is a political hot potato. A government service could point to greater societal benefits to justify funding out of general tax revenue but Amtrak is expected make enough in ticket revenue that they're perennially short of cash. A large part of the problem is simply that railroads have high base costs which can be made up in volume but their service costs more than alternatives because we don't subsidize rail anywhere near as much as highways (for example, DC to NY on train costs more than a bus, but I-95 isn't a toll road funded only by users).

Edit: just to be clear, I'm sure that they're just as flawed as any other group of humans — it's just that whenever you see some obvious problem holding an organization back, it's almost never the case that nobody there has thought about it.

Re:Getting High-Speed Rail Wrong by bluGill on Thursday May 13, 2021 @04:26PM (#27146972)
I'm sure some low level people at Amtrak have thought about it. Upper management has generally not, and thus not allowed the limited funding they could have to be put to good use over the years. A new plan after all is all yours, if you take the old plan your predecessor gets credit (this is also why new CEOs bring in major re-orgs soon after starting - they can't let any credit for success go to their predecessor).
Re:Getting High-Speed Rail Wrong by acdha on Friday May 14, 2021 @09:18AM (#27153932)
What are you basing “upper management has generally not” on — personal experience, media accounts, etc.? From what I've seen in the public discourse, it's looked like fatalistic acceptance of very limited congressional support.

Re:Getting High-Speed Rail Wrong by bobthepanda on Thursday May 13, 2021 @05:24PM (#27147667)
France did but Britain largely did not upgrade the ROW to be straighter.

And it's largely irrelevant anyways because true high speed rail (TGV, HS2, ICE) doesn't start showing up in Europe until the '80s, long after WWII reconstruction wrapped up.

Re:Getting High-Speed Rail Wrong by DrBazza on Thursday May 13, 2021 @11:16PM (#27150292)
The UK has several “mainlines”, all built before WW2. All are fairly straight and have been smoothed and updated continuously since WW2. Anything destroyed in WW2 was repaired as quickly as possible at the time. Britain didn’t really “make use” of bomb damage to change the layout of London as it wasn’t really destroyed.

And then in the 1960s Dr Beeching’s cuts closed almost half the rail network.

The only new high speed railway in the UK opened in the 90s to connect London with the continent, I.e. Eurostar

Re:Getting High-Speed Rail Wrong by willyt on Friday May 14, 2021 @03:51AM (#27151837)

Re:Getting High-Speed Rail Wrong by cletus on Thursday May 13, 2021 @12:11PM (#27143818)
This is exactly right. It's not as simple as just upgrading tracks for high speed. There's only so far you can go around certain turns. There are also likely limits based on how separated the track is from the surroundings. Going 50mph has less of a risk profile than going 200mph. High speed rail is generally elevated and/or fenced off to avoid animals, peoples and objects that would otherwise be deadly.

The UK has this problem with old rail too.

European rail is quite new, probably thanks in part to the "benefit" of Europe being leveled in the last century. China and Japan have new rail too.

Another difference: populations in Europe, China and Japan are more concentrated. Just look at how many airports there are in the US vs Europe. France, a country of 60M+, has a mere handful of airports. So it's easier to serve more people with less line.

Lastly, construction is (now) super expensive in the US.

Sad as it is, I just don't see long-distance rail as being economically viable in the US.

Re:Getting High-Speed Rail Wrong by jcranmer on Thursday May 13, 2021 @12:27PM (#27144040)
> Another difference: populations in Europe, China and Japan are more concentrated.

This is commonly trotted out, and it is false for all practical purposes. The US does have a lot of empty spaces where no one lives--but no one is seriously proposing to hook up empty spaces to HSR. If you instead look at where people in the US do live, it's not all that different from those places. If you mapped out the major cities of the Midwest centered on Chicago and compared it to France, you'll find that the US has larger cities whose distances from the major regional hub are roughly the same as their corresponding cities in France. Since HSR works in France to connect those cities, it should generally work equally well in the US to connect those cities.

Only if people routinely travel to those cities rather than further away cities.

Re:Getting High-Speed Rail Wrong by sjsamson on Thursday May 13, 2021 @04:02PM (#27146672)
CAHSR’s mainline is intended to be SF-LA via the Central Valley, and connect the major cities along the way. Some of those valley have around a 1m+ people or will grow to that over time, making them viable to connect. Think “pearls on a string.”

>Only if people routinely travel to those cities rather than further away cities.

They do. People naturally travel more to places closer to them than further away. There is a strong correlation here. When you’re hungry and want to go out, do you go to a food place 5-10 minutes away? Or a place hours away? Or 3 Michelin starred place on the other side of the planet.

The regions targeted for HSR often have significant auto traffic on the highways connecting them, and short haul flights between their airports. HSR hits a sweet spot for trips that are long drives and short flights. Cost and time competitive, while also being more comfortable.

This is only true in a vacuum without our political and legal environment. If you could make the project immune to CEQA, eminent domain challenges, and union pressure, then you have a much more viable railway. If you could at least brush off two of those three and one of them was the union pressure, then it might actually get built in the manner it was intended to be linking San Francisco, Sacramento, Los Angeles and San Diego. At this point we’ll be lucky to get a line that doesn’t share tracks with freight between SF and LA.

Do you still think that qualifies as "empty spaces"?

Re:Getting High-Speed Rail Wrong by vinay427 on Thursday May 13, 2021 @01:20PM (#27144702)
Fresno (1700/sq. km) also has less than half the population density of Nantes or Nice (4200-4800/sq. km). It's not exactly a fair comparison if the area of the city is far larger unless the last-kilometer transit seamlessly scales to last-2km transit. You can actually walk to a reasonable number of places, or take a bus 1-2 km to many more, from a main station in Nantes, Nice, or any number of similarly-sized cities in many countries.

the only difference between the US and europe that really matters is the degree to which our identification with cars is ingrained, and therefore how that has shaped our development patterns. it's why we have so many large trucks and SUVs even though 75-95% of trips are single-occupancy, why we dedicate so much land to roads and parking, and why we care so little for public transporation, pollution, and transport/energy efficiency. it's not population density, inter-city distance, or patterns of demand, as these are also byproducts of the same phenomenon (cause & effect reversal).
Re:Getting High-Speed Rail Wrong by cletus on Thursday May 13, 2021 @05:39PM (#27147817)
That's not the only difference. People occupy way more space in the US.

sure, and i'd posit that that's also a consequence of our love affair with cars. cars encourage urban sprawl (there's really no such thing as rural sprawl). perhaps a land value tax (with tax deferral until sale for non-wealthy primary home owners) can help us find an efficient optimum, something that would encourage urban density while not discouraging rural expanse.

Re:Getting High-Speed Rail Wrong by clairity on Thursday May 13, 2021 @09:02PM (#27149420)
the car, particularly for americans but also in other countries (mainland china being a prominently rising example), literally embodies individualistic expression, expansive freedom, and bold adventurism, as 50+ years of tv car ads can attest. that's not to pass an overly harsh judgement on any of those things, but rather, to say the balance is out of whack and has been for a while.

in LA, outside of a very few of the oldest core districts, even our supposedly sleepy neighborhood streets are often 40+ feet wide (note that cars are typically 6-7 feet wide), with 15 feet of public easement, and 15+ feet of mandatory setbacks, so urban land use gets out of whack real quicklike that way.

Re:Getting High-Speed Rail Wrong by lmm on Thursday May 13, 2021 @10:56PM (#27150176)

that doesn't matter either. air networks in both the US and europe are plenty extensive.

and to be clear, it's not that high-speed rail is an unmitigated good, but that we love our cars so much that any challenge to their supremacy is a literal (perceived) threat to our own egos.

high-speed rail makes a ton of sense for the coastal cooridors, as well as at least a few interior ones (e.g., the midwest, texas). it's probably not a good use of resources for a cross-continental passenger run of HSR, since air can more efficiently and flexibly link the coastal and interior intercity networks.

It's a virtuous/vicious cycle where in the US we've been building in ways that reduce or eliminate the usefulness of high speed rail while countries that have favored rail have been doing the opposite. The US has always heavily-subsidized roads and automobile travel and as a consequence sprawl. I think it's catching up with us socially, economically, and physically.

In my opinion focusing on cost versus fares is myopic to the point of insanity. As long as we're laser-focused on the economic viability of rail we'll never see any of the other benefits.

We have a responsibility to future generations to not just keep things the same but to make them better, and I think rail does that. If you look around and you dislike your current mode of living, hate your commute, and want to have access to cities, then guess what rail is a solution for all of that. It takes decades to see any real benefit from it though, which is why nobody ever goes for it.

This is the main (and perhaps the most important driving factor) - if you build a rail line from empty land directly into the heart of a major US city, that empty land will develop relatively quickly over the next 10-20 years.

Instead we've done the same but with sprawling highways, which doesn't do much for density (and requires cars, and once you have a car you just use it for commuting).

Re:Getting High-Speed Rail Wrong by bluGill on Thursday May 13, 2021 @12:59PM (#27144469)
Careful there. It is easy to do stupid things and so not get that growth. A HSR from middle of nowhere south Dakota to NYC grand central station will get approximately 0 riders - the distance (all distance in transport is measured in minutes not meters) is too far to commute every day, and there is nothing else to draw people.

I wish this didn't need to be pointed out, but there are a lot of stupid proposals out there. So be on the lookout - don't blinding support HSR: put support where it will be useful.

Re:Getting High-Speed Rail Wrong by PaulDavisThe1st on Thursday May 13, 2021 @02:19PM (#27145416)
There's a common fallacy here: that a line built from "nowhere, SD" to NYC serves only people from either NYC or "nowhere, SD". But that's never true. It would serve people all along the route, people taking shorter, "more regional" journeys. The fact that nobody actually rides the whole line doesn't matter.

Of course, that still may not be enough to justify such a line, but the fact that nobody travels from one end to the other is not an issue.

Re:Getting High-Speed Rail Wrong by bluGill on Thursday May 13, 2021 @04:14PM (#27146808)

Because a big advantage to trains over airplanes is you can stop at places in between for low cost. It is common for airplanes to spend more time getting from the gate to cruising altitude and back down than at cruise.

A train going Chicago to Minneapolis would only lose a few minutes stopping at cities like Milwaukee WI and Madison WI - both fairly large cities. An airplane could stop at each, but the cost of one stop would double the full trip time.

Where a train stops vs go past is a very complex subject full of trade offs. However in general a train that only goes non-stop between two points is a bad idea. I've been in discussions elsewhere in this topic about that - read them for more info. (including those who disagree - they have valuable insight)

Re:Getting High-Speed Rail Wrong by PaulDavisThe1st on Thursday May 13, 2021 @06:01PM (#27148027)
I guess I don't understand, you seem to be explaining why the non-stop aspect is a genuine benefit for trains.
Re:Getting High-Speed Rail Wrong by moshmosh on Thursday May 13, 2021 @07:08PM (#27148627)
They're explaining that cost-per-stop is much lower for a train than an airplane. A stop might cost an airplane an hour or more added to the duration of the full multi-stop route (slowing down, losing altitude, landing, taxiing, boarding, taxiing, take-off, gaining speed and climbing) even if we allow for some pretty serious optimization of processes. It might cost a train anywhere from 1-15 minutes. A train can make four stops between two points and, despite traveling at a much lower top speed, finish the whole route much faster than an airplane would, doing the same thing. That is, it's friendlier to multiple stops over medium-distance routes than an airplane. If you're going point-to-point and it's a very long distance, you may as well just take a plane. If you have a 250 mile route and want a stop every 50 miles, then a train's (way) better than an airplane. Multi-stop (not to be confused with excessive stops) routes are exactly where trains shine.
Re:Getting High-Speed Rail Wrong by bluGill on Friday May 14, 2021 @08:52AM (#27153683)
A HSR train stop and go - without opening the door is about 1.5 minutes added to the total trip time (depending on how fast the train goes of course). It is possible to get the time the doors remain open down to under a minute (this is done for airport trains), but I think 1.5 minutes is a more reasonable floor just because people need some time to get their bags on the train and around other people.

This puts the time loss to stopping a train at 3-17 minutes.

Re:Getting High-Speed Rail Wrong by moshmosh on Friday May 14, 2021 @10:13AM (#27154553)
Sure, HSR is gonna have it worse than a minute, I was thinking of, say, subways and light commuter rail, with the 1 minute lower bound. Some of those don't spend more than about a minute not at full speed for some stations, including door-open time and de-/ac-cellerating. No train where people aren't traveling very light and prepared to get off fast is going to get quite that low a stop time, though, true.

We have plenty of proof to the opposite near where I live. Passenger rail was installed in several locations with the promise of growth that never materialized. One of the lines is from downtown to an airport, through a few miles of neglected neighborhoods that never got the rush of development and gentrification rail was supposed to bring. Another goes from the city through several suburbs and has had negligible impact because ridership is so low.

People prefer not being constrained to the train tracks if they can drive, they prefer to not live near the constant blaring of horns and squealing of wheels on the tracks, and in these days prefer not to be stuck in a cabin full of potentially sick strangers for 2-3 hours a day round trip.

Re:Getting High-Speed Rail Wrong by pchristensen on Thursday May 13, 2021 @01:45PM (#27144989)
"the promise of growth that never materialized."

Was it legal and politically palatable to build there, or in the neglected neighborhoods around it? In the USA, unless you're talking about actual greenfield land, rail-supporting development is usually illegal to build.

Re:Getting High-Speed Rail Wrong by zdragnar on Thursday May 13, 2021 @07:39PM (#27148885)
Rail was sold by the city as a way to promote growth there- aside from hooking up the airport, it was the only reason to run rail at all.
Re:Getting High-Speed Rail Wrong by jschwartzi on Tuesday May 18, 2021 @07:26PM (#27202635)
The central question is how was the land abutting each station zoned? Did they change the zoning to allow for more development? Or did it remain mostly residential-zoned and just change from single-family to multi-family?

The reason rail works beautifully in other countries is that you can get off the train and walk to useful destinations, even if where you disembarked isn't where you live. Shinkansen in Japan have tons of shopping, nice restaurants, and hotels all within a block or two of the station. So there's a reason for non-residents to stop as well as residents. And because everything surrounds the station there's no point for residents to go anywhere else.

>One of the lines is from downtown to an airport

You don’t provide enough specifics about your local situation, but it’s been long noted that airport rail lines underperform. The author Alon Levy’s blog and others in the transit space have covered this. TLDR: They fail serve the local riders well, in an attempt to serve less frequent airport riders who are more likely to pay for a taxi/rideshare, rent a car, get picked up/dropped off, etc. There are often poor airport connections, like people movers or airport connectors, getting to the right terminals, etc which creates more friction and confusion.

>neglected neighborhoods that never got the rush of development and gentrification rail was supposed to bring

Rail and transportation infrastructure generally is an enabler for re/development and land use, but not a guarantee of it. Necessary but not sufficient by itself.

That would be ridiculous, if it would up to 1 hour round trip it maybe would be more effective.

Re:Getting High-Speed Rail Wrong by zdragnar on Thursday May 13, 2021 @07:48PM (#27148941)
It is a 40 mile total run, making a number of stops along the way. The more people it has to serve, the less convenient it becomes.

The other line (running from downtown to the airport) was also a total of 1 hour 30ish minutes including bus from my house to the terminal, then rail down to the airport. It otherwise was a 30ish minute drive, tops, and driving is what almost everyone chose to do if they had the car to do so.

Re:Getting High-Speed Rail Wrong by rsj_hn on Thursday May 13, 2021 @06:15PM (#27148168)
I'm not going to disagree with the arguments you are making as they are valid in their own right, but I will point some to some important tradeoffs your post skips over.

First, there is a fundamental tradeoff between location and transportation. Land is not a produced good, it is owned by landlords and its value comes from location.

Transportation makes prime land less valuable and outlying land more valuable, thus it redistributes value outward, allowing people to escape from the thumbs of landlords and buy their own land. Eisenhower's freeway building project and cheap gas is responsible for the American middle class, much moreso than anything FDR did, as people could move out of apartment buildings in inner cities and buy land of their own, due to the improvements in transportation technology.

For those improvements to work, you have to fan out. A rail line isn't going to get it done, but what a rail line can do is transport people to a remote place and then they fan out with roads. That is a good idea for redistributing people if an area is already densely populated and the land is bought in a large circle around the city. Then you hop on a train to take you to nowhere and there you can buy cheap land. But if the built up area is relatively small, you are better off with a network of cheap roads to carry you to where land is cheaper.

Thus the U.S., which has always had smaller cities surrounded by more open space than Europe, got more bang from its buck with roads. But the same network of roads did not have the transformative effect in Europe as it did in the U.S.

What is interesting is the shift to remote work. The internet has made communication another strong rival to location, providing another threat to land values in inner cities. So it could be that in the future, we will not need so many subsidies for transportation but for things like broadband, to help nurture the middle class and allow people to buy land in remote areas.

People - especially landlords -- are very much aware of these dynamics, which is why historically there was great opposition to roads from moneyed interests, as documented by Adam Smith. And why roads are deserving of subsidies, due to all the positive externalities. In the same way, internet infrastructure is deserving of subsidies today. Whether or not rail is deserving of subsidies in the US depends on how large the disk is of expensive land surrounding cities. In the northeast, it is large, and that's why you see rail in the northeast. In most of the U.S., it's not large at all and you can buy affordable land without traveling too far away from work. In Europe, it tends to be large as well.

With the internet, that is only getting better and both road and rail are becoming less relevant as an agent for the promotion of the middle class land ownership. They are still relevant, but I believe the window has closed on dreams of high speed rail connecting cities in the U.S. High speed internet will get the job done faster and easier, if coupled from a large shift to working from home.

Re:Getting High-Speed Rail Wrong by TYPE_FASTER on Thursday May 13, 2021 @01:01PM (#27144496)
If we wait until areas have high population density, it's harder and more expensive to build through it, and people don't want to fund the project.

If we don't wait and want to build now, people don't want to fund the project due to lack of immediate ridership.

Funny how we keep building roads, and expanding highways, while saying building rail infrastructure doesn't make sense because there aren't enough people to use it.

Re:Getting High-Speed Rail Wrong by Analemma_ on Thursday May 13, 2021 @01:09PM (#27144574)
Why is there this asymmetrical demand that only high-speed rail needs to be “economically viable“? Roads don’t get this demand: tolls and gas taxes don’t even come close to paying for their upkeep, and nobody cares because a transportation network is a public good where accurately billing for upkeep is worth a lot less than the societal benefits.
Re:Getting High-Speed Rail Wrong by willyt on Friday May 14, 2021 @04:01AM (#27151886)
The UK has quite high speeds (125-140mph) on its conventional rail lines all on lines that were first built between 1850-1900 but have been gradually realigned to be faster. Most war damage was to the junctions not the route alignment out in open country so there were improvements in throughput at junctions made by rationalisation of the layout but routes between cities weren’t realigned because of war damage.
Re:Getting High-Speed Rail Wrong by bobthepanda on Thursday May 13, 2021 @05:30PM (#27147726)
The true high speed lines (TGV, Eurostar, ICE) start showing up in the '80s, when WWII reconstruction has been over for several decades.

They upgraded their old regional lines too but that's not really relevant to the experience of new, 300+ km/h rail.

Re:Getting High-Speed Rail Wrong by cletus on Thursday May 13, 2021 @05:36PM (#27147787)
The Northeast corridor in the US was opened in 1834.

My point was that the rail infrastructure in Europe just isn't that old and even in the 1980s you had a huge advantage in building for speed over the 1830s.

Re:Getting High-Speed Rail Wrong by willyt on Friday May 14, 2021 @01:03PM (#27156634)
I don't think that is true. Small bits of the Northeast corridor were opened in 1834 but the whole thing wasn't complete until 1880 or something like that. I think a lot of Europe's infrastructure is as old or older. Especially in the UK where trains were invented and first commercially operated at scale. If you compare to a route of similar length in the UK, on average the ~400miles of line between London and Edinburgh/Glasgow is probably about 20-30 years older. Trains were racing to Scotland from London up the West and East coasts from the 1860's onwards and there was a lot of competition between the two routes to be the fastest. The time over the 400 mile route was down to about 8hrs by 1880 and about 7hrs in the 1930's. These days trains operate on the two main routes at up to 140mph now and it's possible to get a train that does it in about 4h30m with a few intermediate stops. This is not so hot compared to TGV Paris-Bordeaux at 2h10 on a dedicated HSR route but it does compare favourably to Acela's 6h30 over a similar distance also on a legacy route. This is because the alignment has been worked on continuously over the years to improve speed, it's not the same alignment as it was in the 1850's when it was first completed and both East and West routes pass through quite a few cities and towns on the way.
Re:Getting High-Speed Rail Wrong by bobthepanda on Thursday May 13, 2021 @05:38PM (#27147806)
The state of the 1834 track has very little bearing on building new track in 2020, which is how every other country on the planet has built high speed rail.

Re:Getting High-Speed Rail Wrong by jeffbee on Thursday May 13, 2021 @01:11PM (#27144598)
Not only is it "not far off" it's locally higher. Ohio is more densely populated than Spain. They even both have a city called Toledo. The difference is the smaller city in Spain has a high-speed rail link to the capital with 6 trains per day, while the larger city in Ohio has only two conventional trains per day, neither of which serve the nearest city, Detroit, only 60 miles away.

In any sensible universe, the major cities of Ohio would be connected to each other, Detroit, Chicago, and Pittsburgh by high-speed rail.

It’s not that sad. We have lots and lots of other low hanging fruit to pick.

Let’s even further improve fright distribution by rail. Let’s get mass transit within our cities and their suburbs to be less terrible. Let’s have more than a handful of cities in the entire country where people can reasonably live without cars.

Re:Getting High-Speed Rail Wrong by bluGill on Thursday May 13, 2021 @04:47PM (#27147238)
The US does pretty good about freight by rail, and I think they should be left to improve themselves for now. There are a lot of things they should do better, but they are doing okay.

Most cities have terrible mass transit. Good transit is one where people don't have to arrange their life around it. Meaning it comes often, and is reasonably fast.

Re:Getting High-Speed Rail Wrong by jcranmer on Thursday May 13, 2021 @12:22PM (#27143972)
About your second point:

This is kind of partly true. The track in Connecticut in particular is bad enough that you really need new right-of-way as opposed to fixing individual curves here and there (which is the situation for the rest of the NEC). Alon has favored a new right-of-way that's basically right next to I-95 for as much as possible, which minimizes the takings you need between New Rochelle and New Haven. East of New Haven, there's far less density, and it's pretty easy to make a new right-of-way wherever you want to.

The other issue in Connecticut is that, even on the existing right-of-way, Amtrak isn't able to utilize the available speed capacity of the current right-of-way. This is due to Metro North intentionally slowing Amtrak trains down for its commuter rail schedule instead.

Re:Getting High-Speed Rail Wrong by bradleyjg on Thursday May 13, 2021 @01:39PM (#27144933)
I’d bet metro north saves more co2 than you’d save even by eliminating every plane flight between NYC and Boston. Probably by at least an order of magnitude.

It is harder than you think. In 1950 it wasn't a problem, but these days people are aware that a freeway too close to their house is a negative. They will support the next neighborhood - close enough to be easy to get to, far enough away that they don't get the noise and traffic.

Re:Getting High-Speed Rail Wrong by giantrobot on Thursday May 13, 2021 @01:50PM (#27145038)
Your second point is missing some facts that actually make the situation more difficult.

1. Geography and geology is tricky. Rail lines don't curve because the builders just love curves. There's geographic and geologic reasons for a lot of rail line positioning. That's in addition to people living/working/shopping in a place where it would be useful to lay track.

2. Freight lines own most of the track in the US. Amtrak gets to use those lines but freight has right-of-way. Amtrak must side track when a freight train is coming. Amtrak only has a few sections of the NEC as dedicated passenger track. Without dedicated passenger track Amtrak's schedules are all over the place. Freight trains have trouble all the time and passenger trains need to sit and wait while they fix/move the freight train.

Re:Getting High-Speed Rail Wrong by froh on Thursday May 13, 2021 @02:06PM (#27145250)
1. old rail line positioning was also influenced by land ownership and existing human structures. and our know how how to deal with previously difficult geography has evolved. you may want to study "Stuttgart 21" or "gotthard rail tunnel" or Eurostar channel tunnel or Berlin Munich high speed track to get an intuition for what's possible if there is a political determination.

2. France and Japan have dedicated tracks. Germany has reliable high speed freight lines. again more than anything it's a matter of political will.

> you'd have to eminent domain swathes of, say, New Haven

Just to pick apart that specific example, you could instead build a bridge from West Haven to East Haven with much less eminent domain, but much more complaints about the bridge being built.

When a suspension bridge was proposed for where I-95 crosses the Potomac, the residents of Alexandria complained that it would be an eyesore and were able to get a drawbridge built instead of a suspension bridge.
