One major difference is infrastructure. Shinkansen lines are completely separate from conventional rail: no level crossings, no shared tracks, no freight, and no interaction with slower services. There are no cars, pedestrians, or animals anywhere near the line. In much of Europe, including Spain, high-speed lines are very good, but they still tend to interact more with legacy rail networks and inherit more constraints.
Another key factor is how strictly operations are controlled. Speed limits are enforced automatically rather than relying on driver compliance alone. If a train exceeds its permitted speed for any reason, the system intervenes immediately. The design assumption is that human error will happen, so the system is built to prevent a mistake from turning into an accident.
Maintenance is also handled with extreme conservatism. Track geometry, overhead lines, and rolling stock are continuously monitored, with very tight tolerances. Components are replaced earlier than strictly necessary because preventing failures is considered far cheaper than dealing with the consequences of one.
Japan has also invested heavily in detecting external hazards. Earthquake early-warning systems automatically cut power and apply brakes before shaking reaches the tracks, and the same mindset applies to weather, landslides, and other environmental risks.
Finally, there’s a strong institutional safety culture behind all of this. Procedures, training, and reporting of near-misses are taken very seriously, and lessons are applied incrementally over decades. The objective isn’t just to meet safety standards but to systematically remove edge cases.
It’s not a single piece of technology that explains the record. It’s the combination of dedicated infrastructure, automation, conservative engineering, obsessive maintenance, and a culture with very little tolerance for shortcuts.
Regarding the second point, 2013 accident was caused by higher than allowed speed and drivers had been complaining about the line not having the security system that automatically enforces speed limits. In this year's accident, the line has a much stricter securty system.
The main issue with spanish rails, high speed and specially traditional rail is the lack of maintenance.
For example, people typically pay for house/apartment insurance. But insurance companies never send a person to check for things like leaking pipes or whatever. Rather they simply wait until an accident happens and dispatch an emergency crew and cover a lot of damage that could be easily prevented. Then people tolerate non-trivial damage to homes/apartments like leaky roof not reporting it to insurance companies for weeks.
Then with cars people often do not follow the maintenance schedule and insurance companies do not ask for that. Typically people drive until damage happens due to a minor accident or maintenance are forced by state required technical inspection once in few years. The car companies even offer free maintenance checks as a part of guarantee but people skip even that.
Yet when someone spends efforts to complain, thinks do gets done. For example there a city service to remove graffiti on public areas. If one files a complain, they react and remove the graffiti. However sometimes one needs to send a complain twice.
Never I had the pipes in my home inspected, even now that I live in areas where it freezes regularly.
Never has anyone (not even my insurance) forced me to follow any particular maintenance schedule (albeit I'm quite sure somewhere in the fine print it will read that if the accident is because of poor maintenance they'll just ignore the claim).
Here the city service to remove Graffiti is almost overnight, and works better than many other public services...
Does the system automatically slow down the train, or does it notify the engineer? I would imagine that there are some scenarios where going over the speed limit is the correct choice.
https://en.wikipedia.org/wiki/The_Bullet_Train
https://en.wikipedia.org/wiki/Bullet_Train_Explosion
In the movies terrorists place a bomb on board and the train crew has to maintain a minimum speed or the bomb explodes (this is where that american movie with a bus got the idea). And they have to manipulate the ATC or else it will stop the train when they enter sections of the track with lower minimum speed, or else ATC stops the train and the bomb explodes.
That might be because Japan did have a huge railway accident in 2005 due to excessive speed.
https://en.wikipedia.org/wiki/Amagasaki_derailment
> Of the roughly 700 passengers, 106 passengers and the driver were killed, and 562 others were injured
The Santiago de Compostela derailment (first link on the parent comment) happened in 2013 for the same reason.
All that said, I would not be surprised if the culprit for this particular case is lack of maintenance. However I would wait until the official investigation is over before drawing conclusions.
I’m not sure these are comparable, high-speed rail needs much tighter tolerances as the risk is orders of magnitude higher. As the parent comment stated there have been zero major crashes on the japanese shinkansen lines.
There is also no reason to treat speed limits on high speed and normal trains differently. There are plenty of speed related crashes on low speed lines. If anything the stakes are even higher on commuter trains because they tend to carry more people, many of which will be standing, and are more likely to crash into another structure as was the case in the Japanese incident mentioned.
No, Japan more or less invented ATC in the 1960s for the purpose of running the Shinkansen safely.

Not true.

Spanish high speed trains mostly run on their own tracks because of gauge differences. France and Germany are the ones who actually runs high speed trains on old tracks, a lot.
It is surprising how many upvotes you can get on the internet just by glazing the Japanese.
This is called Mini-Shinkansen: https://en.wikipedia.org/wiki/Mini-Shinkansen
This comes with limitations, as the maximum track speed on these converted lines is apparently around 130 km/h.
None of the actual Shinkansen stadard lines have level crossings.
But would it have generated almost the same comment 4 hours ago, when the comment was posted here?
A few months ago I posted a comment in a thread about some new law that would not have been needed if a law from many years early had not seemingly arbitrarily limited itself to some particular cases. I speculated on some reasons why the original law might have been written that way.
A couple hours later I asked an LLM about it (Perplexity) and it gave the same reasons I had guessed. I checked the links it provided to get a suitable reference if the topic ever came up again...and it turned out my comment was its source!
At least in France, high speed trains on older tracks won't go as fast as on the dedicated high speed tracks
Is exactly what a text bot would say. Eloquent, but when you think about it, is just nonsense. Which operator treats HSR as "fast trains on tracks" and which does not treat it is a "tightly controlled system"?
That's why something like a fractured high speed rail track would never go undetected in Japan.

Then the crashed train passed at 19:45.
I don't see why an overnight inspection must have caught this, it could have happened just before the 17:21 train, or even have been caused by it.
We will need to wait for the investigation to continue, and I hope Japan's rail people will not be so arrogant as to assume they can't learn something from it.
Reminds me of when Malaysian airlines crashed two planes in a short period of time. It was a good time to get cheap flights from Europe to south east Asia as long as you can withstand relatives thinking you are literally going to die in their third crash.
And up to that point Russia wasn't known to supply the separatists with an anti air system and the crew to run it.
It absolutely did not. The RCS of an F-14 v/s an Airbus A300 is an order of magnitude different (probably 2 or 3 orders).
> There really was an F-14, just on the ground at an Iranian airbase
There was, but that’s a red herring for the root cause. Each ship’s radar independently and correctly identified and tracked the Airbus separate from the Mode 2 targets, but when communicating the track information between ships, the tracks were mixed up.

> There was a combat camera team aboard the Vincennes, and the footage depicts considerable confusion and even ill-discipline amongst the crew (cheering, shouting, football game atmosphere) that contributed to one of the most tragic events in U.S. Navy history
I'm outside the US so that's probably the cause. Is such information available elsewhere?
But this also works: https://archive.md/XsxT8
And also this: https://web.archive.org/web/20251208110440/https://www.histo...
I put the primary blame on Iran because they cleared a civilian plane to overfly combat they initiated. They set the situation up, a mistake happened.
Fog of war isn't like in a video game where it's just whether you can see something--in the real world by far the biggest factor is identifying what you see rather than simply seeing it.

It absolutely matters.
Flying over a war zone with known anti aircraft missiles is quite different to flying over a low level conflict that is using small arms only.
What was in the news at the time, and the news are still linked from https://en.wikipedia.org/wiki/War_in_Donbas#Escalation_in_Ma...
2 June 2014: "Luhansk airstrike"
14 June 2014: "A Ukrainian Air Force Ilyushin Il-76MD was shot down"
20 June 2014: "The insurgents [...] shot down a Su-25 bomber."
14 July 2014: "Ukrainian Air Force launched air strikes targeting insurgent positions across Donetsk and Luhansk oblasts. The Ukrainian government said that 500 insurgents were killed"
17 July 2014: "DPR forces shot down a civilian passenger jet, Malaysia Airlines Flight 17"
Don’t fly a commercial passenger jet over an active known war zone. Then you don’t even really have to think about whether the separatists below you know whether your signature looks like a fighter jet or not lol.
Never leave your safety to the vagaries of Russian incompetence or malice, surely.
I'm not sure why Girkin would want to shot down an airliner?
as long as you can withstand relatives thinking you are literally going to die in their second crash,
and then you die in their second crash.

> [The] stretch of track that was renovated last May and inspected on January 7.
The track had been inspected very recently. Maybe the inspection standards are inadequate?
The linked article also shows figures that are quite meaningless without context.
> [The] vast majority [of Spain's high-speed rail budget] went to new infrastructure with only some 16% earmarked for maintenance, renewal and upgrades. That compares with between 34% to 39% spent by France, Germany and Italy,
They simply can't compare those numbers as-is. Of course Spain will be spending less in maintenance as a percentage of the total budget if it's still mainly building new tracks. It's not a useful figure.
Spanish officials are very good at deflecting blame and playing politics. Nobody wants to be held accountable for a catastrophe. Also see the 2024 floods in Valencia; a partially preventable tragedy, followed by a whole lot of mud slinging, but zero accountability.
So while inspection standards might be inadequate, I would take anything a senior official says with a pound of salt.
sigh
Of course you're right
English has a third term like that as well called 'brazing', then there is silver solder (a high temperature version of soldering), in dutch we'd call that 'hardsolderen', whereas what the English call brazing we call oxy-acetyleen lassen (which is more of a process name by virtue of naming the ingredients).
Soldadura autogeno and Soldadura en el arco (sp?) are what I think the modifiers used in Spanish to indicate brazing and (arc) welding.
In Germany it would be schweißen.
So, also different with different etymology in a language from a different group (although these things were probably influenced by German)
* the first one makes it clear a something (a different material) is used to join things together
* the second one implies you melt/boil the things to join them together
Conflating the maintenance budget with the money invested in new infrastructure in this way is not very useful. How much money was spent per km of (high-speed and overall) railway track would be much more informative...
The first was purely a matter of not upgrading the signaling in a very low speed section: The crash could have happened with regional trains too. Every engineer knew that it was unsafe and one distraction was enough to get someone killed, but Spain is still well in the middle of track expansion, so it's all the horrors of politicking. Unless you have a crash, not upgrading those signals costs nothing, but, say, the very expensive connection to Asturias was worth a lot, so iffy tradeoffs were made.
Hopefully better engineering-driven tradeoffs are made regarding track maintenance, but hey, this is Spain, not a place where we are good at efficient, reliable safety processes: See the failures in Valencia for the DANA, where the chain between the meteorologists seeing a risk that led to recommending evacuation, and the actual order of evacuation was so slow, so we ended up with 229 deaths.
They run at full speed between regular train operations.
I saw one of them running on my last trip, which is said to be good luck.
Which is the secret of preventing 99%+ of sudden mechanical failures of pretty much any type of infrastructure.
Then you mention fsb and get downvoted.
HN is full of russian shills.
You won't be the first or last asking why Russia does the thing it does. Russia is world's Dog in the Manger, why wouldn't we give it a bit of credit, though?
I wonder if Dang has any tools to deal with that.
But yeah dude, we’re all Russian shills.
It sounds unreasonable sure, but tbh I am not convinced that the Russian government is reasonable.
You can call out the Russians for being pieces of shit without making them the boogeyman for literally everything. Doing the latter just makes you seem like a conspiracy theorist.
This is roughly on par with every celebrity death over the last 4-5 years being followed by idiots commenting "vaxxed?!"
Russia is already doing enough damage and causing enough fear as it is. Let's not help them by baselessly give them credit for every single thing that ever happens.
Hey that infrastructure looks perfectly fine and new, ahhh ok... they were going 180kmh where the speed limit was 80kmh..
Now - Japanese mentality is strange to me, but the quality standards and thought process, are convincing.
Seriously, Cryptonomicon is a bizarre thing to put on this list. I like the it a lot, but none of that book takes place in Japan and the closest intersection is Japanese soldiers during World War II, with a brief participation of a single fictional Japanese company in the modern section of the book.
While this protocol is not oriented toward maintaining equipment like tracks and wheels -- it does seem to be a good indicator that the Japanese deal with these systems and the safety concerns around them differently.
And their track record (pun intended) shows the result of this focus.
https://en.wikipedia.org/wiki/Pointing_and_calling
> Railways in Japan use a safety system called “pointing and calling.” This method of physically pointing toward an item to be checked while vocalizing its name was invented in Japan about 100 years ago. The combination of looking, acting, speaking and hearing reduces errors by as much as about 85%.
I love Cryptonomicon but it engaged in that distinctly American brand of orientalism when it got into Japanese soldiers killing themselves and whatnot.
My tentative conclusion is that there is something really unique about Japanese culture and there is certainly nothing wrong with that.
These are actually points making the Japanese system easier to maintain. Because of smaller surface area it’s much denser.
Japan having to build to earthquake standards, so being more robust overall? Or to specific failure modes, at least.
BART recently got a full-speed inspection car.[1] They needed a specially built one because BART has a non-standard track gauge.
The Federal Railroad Administration has track inspection cars, but only six of them for the whole country. One was seen on CALTRAIN track.[2]
Accountability.
This means that Shinkansen tracks are designed and build to much higher standard.
Also, Far East right now is also massively cash poor yet labor rich relative to the rest of the world. Everything is crazy undervalued and there are clear gaps between amounts of money changing hands vs work being done. Skilled-labor-intensive tasks are going to be much easier when cheap skilled labor is just perpetually available.
High public competency and government capacity allows a lot to get done.
1) Can you expand on your first sentence? When you say user owned what does that mean exactly?
2) If skilled labor is undervalued does that mean those with those positions live kind of meager lives? Or what is that like?
2) I mean, like, it's the place where the English loanword for "death by overwork" came from. Also, undervalued means things costing less than they are worth. Trash costing little isn't undervalued, that's more adequately valued.
Answer 1 is still not clear to me. Can you contrast it with how Spanish track is managed?
I admit that I was a bit uninformed about specifics of Spanish train system in that, the rails were in fact laid by then-Spanish national rail and the operator was then-national company, but still, they don't seem like built and maintained like the BART or the NYC subway that happens to go 200mph in straight sections. That Shinkansen architecture is unique, and that is also guaranteed to be more labor intensive than how everything in most HSRs are.
These events happening 4 times in 3 days are statistically nonexistent. Even less existent is them starting to happen right on the day before a major politician in Spain visits Israel to talk about buying Israeli security and monitoring systems.
What do they do differently?
