What we know so far:

1. The last 3 cars from the Iryo train (Frecciarossa 1000) derailed for unknown reasons. It's a straight line, so this is extremely rare.

2. The Renfe train (Alvia) didn't have time to break and hit the derailed trains from Iryo, the two first cars derail as a consequence of the impact.

3. The Iryo train(Frecciarossa 1000), that caused the accident, was manufactured in 2022 and it passed a technical inspection just 4 days ago.

4. The renovation of this specific part of the infrastructure finished on May 2025, so it's practically new.

Spanish high speed trains are one of the best in the world and it had plenty investment from governments of different sign over the years. This has nothing to do with the regional network (Cercanias) and the local struggles in certain regions.

IMHO, this is a horribly timed accidental technical issue.

The current government has been found to be cutting corners in maintaining the Cercanías commuter railway network[1]. Indeed last year some machinists had to derail a train to stop it from crashing other[2].

The former Transport Minister is jailed because of corruption in public contracts, and hiring prostitutes[3][4].

The government is doing a poor job maintaining the current railway network.

Every government in Spain for the last decade or more has been cutting corners in maintaining the rail networks: high speed (where this accident happened), the conventional network and commuter rail. You failed to mention the fact our budget has been extended since 2023, that the actual track where this happened was given maintenance under a year ago (per the minister, [^1]) and the train that first derailed (Iryo's ETR1000) was last checked 4 days ago.

Regarding the former Minister (Ábalos), he's awaiting trial and not yet convicted (even though, IMHO he is probably guilty), and he hasn't been in the ministry since 2021[^2] so it makes no sense to bring it up when he has been out for nearly 4.5 years now.

I think you are just stirring the pot and cherry picking news.

"Cercanias" is a different rail network to the one where the accident happened (high-speed). Also the political issue that you are mentioning happened 5 years ago on a single individual not directly affiliated to the organization that manages the rail network. Please let's be serious and bring constructive things to the conversation

What does the "Cercanías" conmuter network in Madrid have to do with the high-speed AVE network where the accident took place? They are two different networks, and even if the first one isn't well maintained as you claim, it doesn't mean the other one has to be in the same situation.

Also, it's been four and a half years since the former Transport Minister who is in jail left the office (july 2021).

Where do the articles mention that the current government has been cutting corners? In fact, they have increased the current investment plan on the Cercanías commuter railway network to more than 7,000 million euro, from 5.000 million that the previous government planned[1].

Now, this isn't to that the current political landscape is fine because ( as portrayed by the last articles ) is totally unacceptable, and of course that affects the rail network negatively.

In this particular article they were fact-checking a wrong claim made by the socialist party, to me that shows that besides their alignment, they care about fact checking information. They also mention that the last three development plans were developed by PP ( People's party ) -- if they're aligned with the socialist party, why are they mentioning this and leave the socialist party "in a bad light"?

In regard to the state of the railway network, I totally agree with what you mentioned. Thought corruption will inevitably occur and doesn't mean that the persons above are aware of it nor that the socialist party is intentionally cutting funds. Nonetheless, totally unacceptable.

However, sources consulted by this newspaper assert that the train, out of control, easily approached speeds of 90 to 100 kilometers per hour, ultimately resulting in the derailment.

For many years the Spanish state-owned company RENFE had a monopoly on Spain's huge high speed rail network. However their high prices, inconvenient schedules and poor customer service were often criticized, and so when, to the annoyance of RENFE and many spanish politicians, additional foreign operators entered the market on the key Madrid - Barcelona route, ridership doubled whilst ticket prices halved.

So I would standby for this tragedy to be used for political purposes to try and get foreign operators banned from Spanish tracks, regardless of the facts of the matter.

This is an ignorant opinion. For multiple reasons.

Derailing under these circumstances is a track issue, which means ADIF, the state's infrastructure maintainer, is under suspicion. Not operators, the state's infrastructure maintainer.

Liberalization of the railway sector is an EU-wide mandate. It's not some whimsical slip of a single country's leadership.

Years ago there was an AVE derailment in Santiago de Compostela. No one banned RENFE from the lines.

The machinists complained for years about the curve of Angrois[1][2], and indeed no security assessment was done on the curve[3]. The government during that time (of the same party than this one) did nothing.

It looks like you're quite interested in pointing out that the culprit of this 2013 accident was the same party which is now in office, but even if we take a look at your sources, it says something different:

"Las víctimas creen que hubo cuatro decisiones críticas. Primero, el cambio de proyecto original realizado por Blanco, que suprimió el sistema de seguridad ERTMS en la vía justo antes de Angrois. Segundo, la decisión del ministerio de Ana Pastor de desconectar el sistema embarcado en el Alvia, desactivando una medida técnica que habría ayudado a mitigar el riesgo de un error humano como el que tuvo el maquinista. La tercera decisión fue ignorar un aviso por escrito de un jefe de maquinistas advirtiendo del riesgo en la curva de Angrois. La cuarta, que Adif y Renfe permitieron poner en servicio la línea sin haber realizado el análisis y evaluación de riesgos que exigía la normativa."

There we can read that not only the former minister Blanco (socialist) was to blame according to the demonstrators, but also Ana Pastor (conservative) whose party was in charge when the accident happened.

"Semaphore" is (old) Greek and means "sign (sema) bearer (phore)", and actually the meaning in railways and computing is more or less the same: in computing, a semaphore signals if a resource is in use; in railways, the resource is a segment of a railway line, and the user is a train.

Looks like a Frecciarossa 1000 derailed in 2020 but it was due to a manufacturer defect in a track switch replaced the night before.

The defect was not caught by the manufacturer or the system operator. It was due to two crossed wires in an assembly.

In fact the story is even more tragic when you know that the day before, they also were too fast in the same turn and in the records you hear something like « few, that was close, better take care next time ».

However, for sure this crash should have never happened but it only happened because they were testing the limits of both the train and the track.

It’s literally like a test pilot crashing an airplane while testing all the limits : it should never happen but they are still there for it not to happen in commercial flights.

No. It happened because they were under-prepared and disorganized, and thereby didn't respect the speed restrictions for the segment of track they were on.

They crashed entering a 175 km/h segment at 265 km/h, which is well above the 10% overspeed they were theoretically testing that day.

In the EU it's safer than flying, with 0.5 deaths per 100 billion km/ passenger vs 3 deaths per 100 billion kms/ passenger. However, since an airplane flies at, let's say, six times the average speed of a train, the actual probability of dying during a 1-hour trip is almost 40 times more on a plane than on a train.

> I would imagine crashes on these high speed lines (which always seem to be run at a higher level of professionalism than the general networks) are rarest of all

If this crash is anything like the other ones, you might be surprised. Safety complacency tends to cause maintenance failures. Plus the low speed lines are less deadly since the total energy is proportional to velocity squared, and v is low.

In other words, it might be more helpful to look at it as "if they’re run at a higher level of standards, it’s because they have to be".

Statistically you’re probably right, but considering how many brain cycles we waste on non-essentials, it’s just as fun to waste them on this. That way you can start a nerdy conversation with your travel companions, and they can learn to travel without you next time.

crote 2 hours ago
> Plus the low speed lines are less deadly since the total energy is proportional to velocity squared, and v is low.

You're forgetting about the probability of a crash.

The vast majority of train crashes is due to an impact with a vehicle on a railway crossing.

However, high-speed rail is grade separated, so it doesn't have railway crossings, which means the main cause of crashes is fundamentally impossible.

In other words: Regular rail has a high rate of crashes (with a small number of fatalities each) due to car/truck drivers screwing up. High-speed rail has a low rate of crashes (with a large-ish number of fatalities each) due to catastrophic failure of track & train equipment.

Consider the "booth seats" in trains and busses. So people can chat etc facing each other. If you've got a waymo with your friends why wouldn't you want the seats facing each other so you can be social, excluding this safety factor.

Sitting backwards is beneficial if looking at accidents.

But sitting backwards is very very uncomfortable if there is any kind of uneven acceleration, bumps, swaying, rolling, curvy tracks or whatever. Humans need to look forward at the horizon to get their visual stimuli aligned with their motion/balance sense in the inner ear. If that alignment isn't there, you will get seasick. Backwards makes this even worse.

Babies don't suffer from this, because closing your eyes helps, and infants don't have as strong a reaction to motions anyways, due to them usually being carried by their parents until walking age. So reverse baby seats only work for babies.

I enjoyed watching that - though it wasn't really related to the seating direction, specifically.

Are you one of the safety engineers? Have you discovered anything which isn't included in normal safety tests which should be?

Infant car seats face backwards, they recommend backwards facing for a long as possible (until the kid is too big to fit comfortably in a backwards facing position).

It's incredibly beneficial. However many people dislike it and want to be facing the direction they are moving in, so best case is probably a train-style 4-seater. Which 2 seats facing forward and 2 backwards.

From a derailed train on a straight stretch of track... no. Very likely maintenance related somehow.

New isn't always better. Lots of these types of accidents are because there was a repair or update that caused the failure.

Please don't post like this on HN. This kind of comment is a generic tangent (and a rather ghoulish one), that can be made about any tragedy; yes, no matter how bad something is, there's always something worse. It's the fact that this is an unusual occurrence that makes it noteworthy. The guidelines ask us to converse curiously and avoid generic tangents and shallow dismissals. https://news.ycombinator.com/newsguidelines.html

FWIW: a single car crash killing 21 people would still be newsworthy in America. And I think if you math it out with something per capita equivalent, this would actually be an exceptionally bad day/incident for the US.

But of course you're not wrong, trains are vastly safer than private cars. If anyone uses this as evidence against having a proper rail system, they're ignorant.

But - until someone does that, there's no reason to make this about the US or cars vs. trains. It's borderline offensive to reflexively politicize this before anyone else had; it almost feels like you're intentionally trying to sow conflict, here.

~107 people die per day from car accidents in the USA [0].

0. Per 2024 stats from the NHTSA (https://www.nhtsa.gov/press-releases/nhtsa-estimates-39345-t...)

Right, so, mathing it out, the US has a population of around 340 million but Spain has a population of around 49 million. 340/49 is roughly 7, so the per capita equivalent in the US would be a single incident killing 21*7=147 people. So that'd be one incident killing 1.5x the average number of people usually killed across the rest of the country combined.

Like I said, a pretty bad day.

deaux 6 hours ago
A completely unremarkable day, more like it. Given stochasticity there's bound to be at least a dozen days per year with 50% more than the average, especially since car deaths depend a lot on weekday, holidays, weather and so on - much moreso than train deaths. No one would look up from it, wouldn't make the news.
wk_end 6 hours ago
You're assuming it was the only incident in America that day, rather than an exceptional outlier stacked on top of the usual day in America.

Yes, a single car crash killing 150 people would make the news. It would be among the worst, if not the single worst, car accident of all time [0].

This is now how I interpreted "bad day", think it would be clearer to remove "day" if that's what you meant. Of course you're right in that it would be awful as a car accident, they simply don't happen that many as a time. Which is why our monkey brain's lack of emotional response to "many small cuts" vs "one big cut" incorrectly causes the belief that cars and e.g. coal/gas are much safer than they are.

> how do you mess up a straight line?

One thing I learned working on a system that did train positioning for the 7 Line subway in NYC is that train systems are a lot more complicated than just straight lines. They are complicated networks with custom signaling and the trains don't necessarily travel on the usual side in the usual direction at all times.

That said, in this particular case it basically was just two straight lines side by side and one of the trains derailed and travelled into the path of the other track.

Trains don't often derail on straight sections, likely either someone fucked up really bad on rail maintenance or someone sabotaged the rail.

See the graph titled "Rail accidents by type of accident". There were 63 derailments in 2024; most of the accidents were non-fatal accidents of this type: https://ec.europa.eu/eurostat/statistics-explained/index.php...

The bulk of those are accidents involving railway crossings. There is a program to get rid of all level crossings in NL but it will take a lot of time and cost a ton of money. But there really is no way in which you can make a level crossing safe in combination with normal train speeds.

American trains are largely freight travelling long rural distances. You didn't mention it, so I presume because you didn't take it into account, so your statistics sound to me like they don't mean anything comparable.
toomuchtodo 5 hours ago
Derailments are common is what the stats show. US derailments are largely property damage as they are freight centric, while in Europe, passenger deaths are higher due to more heavy passenger utilization. Derailment is hard to defend against.
Symbiote 5 hours ago
No, they are not common. The numbers you've been given are completely wrong.

The GGP has quoted the derailments figure from the USA page, but the total accidents (including trespassers and level crossing accidents) for the EU.

The EU page they cite says there were 63 derailments in 2024.

A derailment in Europe tends to make the news even when there are no injuries.

This single accident has killed more train passengers in Spain than were killed in the whole EU in 2024 (16).

a high-speed train travelling from Malaga to Madrid derailed and crossed over onto another track

Dylan16807 3 hours ago
Yes we know it derailed, that's not the answer to *how* it failed on a straight line.

How in the cause and effect sense, not which direction it went.
