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 techni…

Assuming no foul play, it's going to be a Points Failure, isn't it? Like Potters Bar (2002) where most of the train makes it through, but rattles/breaks some weak point that was just holding on, and the last carriages change tracks. But at 250mph. Shocking stuff.

The train in question is a Frecciarossa 1000 https://en.wikipedia.org/wiki/Frecciarossa_1000 The Italians designed it but won't run it at more than 300km/h in Italy citing local infrastructure concerns. I guess that leaves other countries to find the edge cases. I'll be interested to find out how fast it was going during the crash.

Yeah but for this accident both trains were well below 300 km/h at the incident site. Around 210 km/h I think.

As an American with no good rails, I've always been curious: what stops a crazy person from throwing a boulder onto the high speed tracks, or a raccoon getting on it, or other such derailment attempts? Is there high security electric fencing all around the track the whole route or something like that?

> Is showing that the government is underfunding railways being misleading? When the accident happened in a different rail network than the one you're highlighting as being underfunded, yes, of course. In what world wouldn't this be misleading? Not even our shit TV networks does stuff like that, and they're generally very quick at being partisan and misleading.

In a world where there is underfunding in all railway networks, both Cercanías and high speed railway (other thing is that you don’t want to see it).

Animals become a fine red mist when presented with these sorts of forces. The train feels a bump, but will not crash. I'm unsure at what size a rock will cause issues, but I would expect in most cases they would be kicked away by the train without issue, if a person can move them.

Doesn't need to be underfunding, may 2025 was last summer and this was the first winter, defects in laying the tracks didn't have a chance to show up until now. The biggest part then might be that they should have listened to the operators warnings and scheduled a proper re-inspection of the route once they started warning of issues.

> defects in laying the tracks didn't have a chance to show up until now. Defects in laying the tracks have a chance to show up on an inspection, either the final one when building or one done at the regular intervals. If it doesn't shows up, your inspection is bad. If you can't inspect what you build, you can't build it.

all in-laws experts in recession or vulcanology or bitcoin has turned to civil engineering experts.

Not having fail-safes is the issue itself.

So smart, do you not understand the question? Don't answer if you can't, instead of trying to weasel. You're acting like the Spanish politicians now.

You are answering all my comments with dismissing my points. Are you angry at them? Feel that your party threatened by them?

You are acting like a good politician servant. I am bringing facts to the conversation while you try to derail it.

There is data from the aviation industry for example that engine incidents on an engine that is certified for some thousands of hours of operation between inspection happen disproportionally in the first 100 hours (and then again at the end o…

I didn’t know this concept had a name, so thanks for that. Now I have a fancy sounding term to tell my manager why I won’t touch that ugly EnterpriseJavaBeans codebase and that we need to rewrite it from scratch.

Is information war telling that the railway transport authority was aware of issues in the accident location for years?[1] [1]: https://www.elespanol.com/reportajes/20260119/adif-notifico-...

large parts of your post have been debunked.

Nothing has been debunked.

We do have good rails, but they're regional. the NE Corridor is pretty solid overall and METRA and Amtrak in the Chicago area works quite well.
