This is not a preliminary report yet, but presents interesting technical data, including a description of how the system works and a detailed timeline of what happened pointing towards the detachment of the balancing cable at the anchoring socket of the cabin that crashed.
mixdup•2h ago
It's also incredibly detailed for a report on an event that happened 3 days ago
davelondon•1h ago
Just what I was thinking! Normally these things take months...
evanjrowley•6h ago
A very unfortunate fatal accident for those involved. It is a sad outcome caused in part by the failsafe mechanisms not being designed situations where the cable broke the way it did. I hope these can be re-engineered to overcome such failures.

I only recently learned what a funicular was thanks to the diagnonal elevators in video games series of YouTube videos by sync-on-luna:

Hopefully that's what this investigation will lead to. Nice videos.
robocat•5h ago
Key lines:

> the air brake and the manual brake were quickly applied by the brakeman of cab #1, but that in the current configuration, the brakes do not have sufficient capacity to stop the cabins in motion without their empty masses being mutually balanced by the connecting cable. Therefore, the existing brakes does not constitute a redundant system in case of a failure in the connecting cable.

DetroitThrow•5h ago
So, the brakes would have never worked if connecting cables broke? And this specific failure has just never happened before? Jesus.
vlfig•4h ago
Although it isn't yet clear how much the brakes did actually brake, it is known they would never be enough.

So the cable was a critical component and initial findings suggest it wasn't being verified as rigourously, thoroughly and often as it perhaps should have.

mastazi•2h ago
> it is known they would never be enough.

No that's not what it says. Brakes were not enough "in the current configuration" in other words they were not applied fully. The investigation will focus on why brakes were not applying full breaking force.

In railway jargon "brake configuration" refers to "how much are you braking" but you seem to have interpreted "braking configuration" as "the number and type of brakes that are currently installed in the vehicle"

sho•33m ago
While I personally lean towards your interpretation, the language is ambiguous - perhaps intentionally so - and it is premature to read too much into it in either direction. We’ll just have to wait.
phire•3h ago
The report only states the conclusion that the breaks did not work for the current configuration.

Which is a slightly awkwardly worded way of saying, “well obviously they didn’t work because we know they were applied and look at the result“

This is only an initial report. They still have no idea why the breaks didn’t work, and for how long they haven’t been working. Could have been a recent malfunction, something that happened during redesign, or a an inherent flaw going back to the original design.

mastazi•2h ago
No that's not what it's saying. I've read the whole report. The hydraulic brakes are designed to be applied automatically and stop the car in case of cable failure. By mentioning "current configuration" the report is implying that the brakes were not applied fully, and the reason for this is still being investigated
DetroitThrow•26m ago
>By mentioning "current configuration" the report is implying that the brakes were not applied fully, and the reason for this is still being investigated

Thank you for clarifying since the brakes never being able to stop a high up car is an alarming design. It does make me imagine the reason for this failure will be some horrificly implemented operational process.

Totally unrelated but there’s a Portuguese language Cold War miniseries on Netflix called Gloria that is excellent (set in Gloria city). I just happened to start to watch that this week
weinzierl•4h ago
Watched it front to back in Portuguese a while ago. It is one of the few series available in European Portuguese, most are Brazilian.

I'd say it was time well spent, it is an entertaining and capturing thriller and you learn a bit about a certain era of Portuguese history.

What annoyed me a bit was that it had many small period inconsistencies. Little things like modern buildings, modern cars visible in the background, the Yamaha grand that did not yet exist in 60s and so on. Where it shines are the landscape shots.

rcruzeiro•3h ago
When watching it, the thing that would consistently real the period piece illusion for me were the modern cranes that you could often see in the Lisbon scenes.
