Spain derailed with Gareth Dennis
S
0:40speaker_1HOST
So not an easy introduction, but when I came across your work, I was impressed by how dispassionately you were able to look at the incident without anger in the moment and give a clearer breakdown of the situation where here in Spain, there was a lot of heat, but maybe not a lot of light.
S
1:01speaker_1HOST
So if you just like to briefly introduce yourself, and then if you could, to layman like me who don't know, there's a lot of talk about the LZB system, this kind of more antique system that Spain's using.
S
1:17speaker_1HOST
What role did that play in this tragedy, essentially?
G
1:21Gareth DennisGUEST
Yeah, so hello, everyone.
G
2:01Gareth DennisGUEST
And that's not... apolitical, the politics is absolutely part of that story, but it's also understanding the systematic failures and obviously the engineering failures underneath those and fitting those together.
G
2:14Gareth DennisGUEST
This incident is horrific and You know, I was prominent in the discussions around Adamuth at the start of the year and was, I think, probably the first person, one of the first people to lay out exactly how it happened well in advance of the formal investigation and possibly helped steer some of the media to make sure the pressure was on to ensure there wasn't, you know, distractions around the cause or suggestions around human error again as some sort of easy to dismiss cause.
G
2:48Gareth DennisGUEST
So, LZB.
G
2:49Gareth DennisGUEST
We'll come back to human error.

If Puente went, and I suspect if he hadn't, that would have guaranteed a failure at the snap election for PSOE, for the Socialist Party.
G
6:10Gareth DennisHOST
So there is Puente oversaw either an inadvertent or I suspect deliberate effort in Spain to focus attention on an individual rather than on management or ministerial failures, such as, for example, the failure to complete LZB replacement on this line.
G
6:24Gareth DennisHOST
More on LZB in a minute.
G
6:25Gareth DennisHOST
Human error is always a symptom, never a cause.
G
6:28Gareth DennisHOST
That targeting of blame, well, we're going to cut to that momentarily.
G
6:32Gareth DennisHOST
We'll come back to Puente.
G
6:34Gareth DennisHOST
We have to talk about obsolescence, safety, and safe systems.
G
6:37Gareth DennisHOST
Within this section, I've been asked a lot of questions around having analyzed the sequence of events, what's my view on failings in the safety systems that led to the tragedy? How does LZB system, that signaling system, work in practice? What are the procedures if that system fails? How does that system differ from modern ETCS, European Train Control System? What are the main technical differences in speed monitoring, braking supervision, operational safety? How does LZB compare with other train protections in signaling systems used across Europe? And how do I view the fact that the LZB system has crashed 170 times this year? These are some of the questions I've been thrown, and then I'm gonna pick off a few elements of that.

And they are in the midst of three days of mourning here in Spain as the prime minister vows to uncover every detail of this tragedy.
D
12:11Damien WilleyHOST
LZB is the train protection system in question here.
D
12:15Damien WilleyHOST
In the event of a malfunction, the fallback measures are forced to compensate for the loss of normal protection.
D
12:20Damien WilleyHOST
It's not advisable to leave the railways in the hands of the frontline staff, hoping that they will fill the gaps at emergency levels by miracle.

El accidente se produjo en Urda, una localidad de la provincia de Toledo, donde se encontraba parado un tren de Iryo, una compañía privada con ciento cuarenta y siete pasajeros a bordo.
J
1:58Jorge EspinosaHOST
El tren debió detenerse porque el sistema de seguridad LZB alemán había presentado una falla a las ocho y media.

2:06Juan Carlos IragorriHOST
Varios kilómetros atrás, otro tren, en este caso un AVE de la estatal Renfe con trescientos noventa y siete pasajeros, tuvo que parar por el mismo problema, pero siguió la ruta cuando así se lo indicó el controlador de la estación de Atocha en Madrid, que le ordenó retomar la marcha normal.

Espagne, tragique collision de trains : 68 morts près de Tolède

0:38Rachel CostaHOST
Les premières enquêtes menées par le ministère espagnol des Transports dessinent un tableau composé de défaillances technologiques et de décisions humaines extrêmement discutables.
R
0:47Rachel CostaHOST
Au cœur du drame se trouve le dysfonctionnement du système LZB, un dispositif de contrôle automatisé qui gère la vitesse et la distance de sécurité entre les convois.
R
0:56Rachel CostaHOST
Ce système, essentiel pour la sécurité des voyageurs, a subi un blocage total qui a affecté six trains en transit dans la zone, dont un train à grande vitesse de la compagnie nationale Renfe et un de l'opérateur privé Iryo.
R
1:08Rachel CostaHOST
La panne qui a paralysé le réseau, le problème a commencé vers 8 h 30, mercredi matin.
R
1:13Rachel CostaHOST
Une défaillance de communication a frappé trois ordinateurs du réseau, déconnectant complètement le système LZB.
R
1:20Rachel CostaHOST
Ce black-out technologique a contraint les six trains présents dans le secteur à s'arrêter brusquement pour des raisons de sécurité.
R
1:26Rachel CostaHOST
En l'absence de contrôle automatisé, la gestion du trafic a été transférée en mode manuel au centre de contrôle d'ATOCA à Madrid.
R
2:13Rachel CostaHOST
L'impact a été si puissant qu'il a entraîné au moins deux voitures en bas d'une pente, causant leur destruction.

So it was quite surprising what occurred.
S
57:01ScafiHOST
So what happened was Spain has a system called LZB.
S
57:05ScafiHOST
It's an automatic train protection and signaling system.
S
57:10ScafiHOST
So basically what it does, it tracks trains in real times And it automatically applies brakes to trains if they see that they're going to either collide or they're going faster than they should.
S
57:55ScafiHOST
I actually had a friend of mine earning his PhD trying to develop a software that could try to do some of that.
J
58:01JulesPANELIST
Amazing.
S
58:03ScafiHOST
So what happens is that they have this system called LZB, and this system is a train protection system, but that system went down for a stretch of 68 kilometers.
S
58:12ScafiHOST
Now, they knew that, and the system issued a red flag and said, hey, we cannot locate trains.

COLISIÓN de TRENES en TOLEDO: MANIFESTACIÓN en DIRECTO y TODOS los DATOS para COMPRENDER lo SUCEDIDO
E
8:24EnriqueHOST
¿Qué ocurrió para que los trenes de alta velocidad coincidieran en el mismo tramo de la vía, según las primeras investigaciones recopiladas por ADIF y el Ministerio de Transportes? Y os cuento porque luego vamos a ver las declaraciones que vais a ver lo del problema informático.
E
8:38EnriqueHOST
Y dicen: hacia las ocho y media de la mañana se produjo una caída en la señalización del sistema de seguridad LZB, un fallo informático que obligó al tren Iryo a detenerse por precaución.
E
8:52EnriqueHOST
Aunque el convoy de Iryo había reanudado levemente la marcha bajo el sistema secundario ASFA, continuaba prácticamente parado.
E
9:01EnriqueHOST
Las primeras explicaciones apuntan a una concatenación de fallos y a un posible error humano o de coordinación desde el centro de control de Atocha al autorizar que el tren AVE entrara en la misma si-sección sin percatarse de que la vía no estaba libre.
