Might sound a stupid question but the article on the web page quoted above says towards the end of the article that Spain's airport authority are investigating......why are the airport authority involved? Geoff Log in to reply |

From the pictures I have seen it looks like a Talgo train (Articulated short coaches and each coach has 1 axle with 2 small wheels) Not nice news to hear, and condolences to everybody involved. Calv Log in to reply |

Report in the Grauniad that it entered a 80kmh curve at 180kmh. Picture showing one carriage flung over the retaining wall (seemingly landed upright), that wall must be at least 10m high so there was certainly a lot of energy involved (tends to support the idea the train was travelling very fast). So the question now is why? Which takes us into realms of speculation I don't want to enter (I don't even have any private ideas).

Is there no equivalent of TPWS overspeed in Spain?

It appears that there is no European Rail Traffic Management System at that point where High Speed trains (AVE, Alvia, etc) use track originally engineered in the Franco era as there was no room to build new tracks. See details in El Pais here if your Spanish is up to it.

Some thoughts beginning to emerge as I hear various snippets. If I understand it correctly, this line has ERTMS. But Barry's link shows there are lineside signals so I imagine it's Level 1. Regardless, that should provide speed supervision. So I have questions in my mind about the working of ERTMS: the balises should have triggered an intervention to reduce the speed of the train to a safe level; why didn't they? Was there some deficiency in the data? Or did the on-train equipment not respond properly to the data it received? Driver disorientation seems unlikely; the approach, with that tunnel, seems quite distinctive. But driver reliance on a speed reduction warning from the ERTMS is certainly plausible, especially if he's trying to regain time by running to the limit and braking only at the last minute. Lot of questions. But I'm beginning to think there might be at least a little more to it than driver error. Log in to reply |

" said:
This section of track does not have ERTMS. It uses the older Spanish system ASFA. This provides a warning when the first beacon (or Baliza) is passed and then a further warning if a second is passed at excess speed. It appears that the effect of applying emergency braking to just the tractor car, rather than across the whole train may have had something to do with the derailment. Further details here (in Spanish). You can hear the beacons being passed on the video link provided by Barry M (above). This link quotes the driver, saying "I f***ed up!"

Spanish Railways do have ERMTS but it finishes before it gets to the Curve. There is an older safety system at the crash site but I have no idea what it is. There is one thing that does bother me. First we must accept the the train entered the curve at a speed well in excess of the speed limit. The CCTV footage and the resulting carnage prove that beyond a doubt. The official word is that there were two drivers on the train but only one was being investigated. First, was the 2nd driver in the Cab? I assume he was. 2nd, what was the 2nd driver actually doing at the time e.g. sleeping, reading a newspaper or observing the first driver? If he was observing the first driver did he warn him that he was approaching the curve at two high a speed? I suspect that somebody, either an individual or a Company will be facing criminal charges due to the high death toll. Log in to reply |

Looking at the video of the crash you can see immediately that the curve is not banked for a speed anywhere near 100 mph. Its hard to see any banking on that curve at all so its not surprising that the train could not hold the track on the curve.

I wouldn't expect the driver to be in a good mental state now, or particularly right after the accident so would still hold off on condemning him (and any other staff) based on a confession when in a state of shock before all the evidence is in.

Why was that camera there? It's been mentioned as a "security" camera, but to secure what? It seems to be the only camera in the vicinity, and it's pointing directly along the tracks, not at the bridge or the walls with the graffiti.

The driver of the train has been arrested as he said on Facebook how cool it would be if he went over the speed limit and get caught doing it by the police.

My interpretation of his statement on Facebook was that it would be a blast to set off the police car's radar as he would be breaking the road speed limit.

I sincerely hope this does not turn into a Lynch Mob mentality. This will hamper the efforts of the Enquiry to conduct a thorough investigation. I feel the Enquiry needs to address two important issues. Firstly the role of the 2nd Driver, both at present and in future, if the Enquiry feels a change is necessary. If it is the case that the 2nd Driver does not have to be in the Cab then surely the rules should be changed as this would most likely have prevented this Disaster. The 2nd Issue is more likely to be both a Railway and a Political one. This is ERMTS. Had it been in place it would have almost certainly prevented this accident. What plans are in place to extend it and how much of the rail Network will it cover if any? ERMTS must surely be considered an important safety investment. Log in to reply |

It's interesting to speculate upon the mentality of the driver of the train. Perhaps he was under the allusion that he could go at any speed on a curved section of track. If this is the case then it is very worrying. Most people are aware of the laws of physics through mishaps in childhood. e.g. falling off a bike at speed on a bend. These experiences teach us respect for speed in a moving vehicle. Do children learn these things nowadays in this computer age ?

Regarding the ETCS, supposedly the train was on track equipped with such, but that ended shortly before the curve (and the cab ride video posted earlier appears to back that up). That got me wondering - talking generally here as there must be other locations with similar issues - whether the system is programmed for events outside the control area, or whether it just "sees" the end of the line at 200k/h (or whatever) and anything beyond is not known. In other words, is there a ramping down of speed towards the end of ETCS sections in anticipation of upcoming speed limits outside the ETCS control area?
