If you’re interested in this kind of thing, look up plainly difficult on youtube. He has more videos on train crashes than I’ve seen, and I’m embarrassed how many I’ve seen. Here’s one to get you started: https://youtu.be/VV2rIHEp5AM?si=sSBT9s49PqbLTGbt
There are a lot of safety lessons embedded in these videos, which is why I like them. I also did a double take when I heard "semaphore"; its history goes back far longer than the ~century of software engineering. https://en.wikipedia.org/wiki/Semaphore
Oh you silly duck! Semafor is a common word in a handful of other languages for things like traffic lights and such. I had to do a double take when I first saw it in a programming class.
Also hope you’re doing well it’s been a minute since our paths crossed on gdnet.
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.
AnsaldoBreda did also manufacture the Fyra trains for the short-lived high-speed trains here in The Netherlands. After three trains lost parts in the first month, it was banned from operations. https://en.wikipedia.org/wiki/Fyra
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.
I know a lot more engineering goes into these trains due to the higher stakes. Japan’s high speed rail hasn’t had a fatal accident in 60 years. I’m wondering what the cause of this will turn out to be.
Actually the defect was detected by the operators, who installed it that night. They disabled the switch, but apparently this didn't reach the day shift.
Train crashes like this are _so_ rare. It's not as safe as flying but AFAICT in rich countries it's the same rough order of magnitude in terms of danger level.
I don't have data but 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.
I don't think it's a good use of mental energy to plan for a crash like this. You're better off using your brain cycles on hygiene or not losing your luggage.
Brain cycles aren’t a limited supply. Besides, you’ll get to feel a nice jolt of serotonin when you remember to sit backwards.

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.
I feel like airplanes should be designed this way. Outside of takeoff and landing it would be pretty hard to even notice the difference, once you're seated.
At least BEA airliners used to have quite a few backward facing seats, up to half the plane.
However, there were a number of problems - people didn't like sitting in them, people didn't like hearing that their seat wasn't as safe as the others, you can't get as many rows in unless you turn them all backwards, and the structure needs to be designed differently so then you need more spares.
Huh. I'd never thought of this. If that is actually meaningfully beneficial, I wonder if they'd design self driving cars with the seats facing backwards, given there's no longer a necessity to look at the road.
(edit: I guess it's more of no-brainer on a train/bus where you don't have a seat belt)
Not the author, but I think there was some research and it's indeed better for you if you have head support, to be facing back towards the front. If prevents a whole range of injuries, from your neck, to becoming a projectile yourself.
But it's really theoretical, and does not account for the passenger in front of you headed head-first into your throat.
PS: I laughed hard that xlbuttplug2 is answering to deadbabe. The internet lives!
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.
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.

No cause is known yet, but based on the videos, what’s the most likely reason for crashes? Bad tracks? Some human error resulting in collision?
The train in question is a Frecciarossa 1000 https://en.wikipedia.org/wiki/Frecciarossa_1000

Always try to sit in seats where your back is toward the direction of motion.

Interesting. I didnt know this, i always get motiom sickness if i sit facing the opposite direction.
Not sure what kind of cars you drive but in mine all the seats face the same direction. Why would they change that when making it safer?

Disclaimer I work for Zoox, but here is us crash testing https://youtu.be/597C9OwV0o4
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?
