The Michael Crick article seems to say the "fault" is that the barriers stay down too long i.e preventing road vehicles from moving forward. If so then this is if anything a "fail safe".
What absolute tosh. For an AHBC▸ the road closure time is a minimum of 29 seconds and worse case (for two trains with the first striking out just as the second strikes in is 29+10+29=68 seconds). It may be slightly longer if the trains are not running at linespeed but the normal calculations are based upon 80% of trains arriving within the 29 seconds. I don't think that the train passing time is likely to add much to that (depends on train length) so say worse case is crossing closed for 90 seconds. Edit to add some extra comments: My professional experience shows that most AHBC level crossings are only closed to road traffic for around 45 seconds at the most at any one time (accepted that the number of closures may follow each other quite closely, a minimum of 10 seconds apart). As we have debated many times before on this forum, level crossings are safe if used properly (would you cross a red light at a road junction??). Despite what I have said here my sympathy still goes out to the family who lost a dear loved one (and to the train driver to whom it must have been quite a shock). |

Indeed, and much quicker than at CCTV▸ or locally controlled full barrier crossings where several minutes is often the norm. |

Not really sure this is a technical problem appears to be inappropriate equipment.
Or inappropriate use of appropriate equipment. We will only know when the report into the accident is published. |

Indeed: thanks for your restrained comments, everyone, in such sad circumstances. I've moved and merged a couple of topics here, as the discussion was a duplication - purely in the interests of continuity and completeness, as always. Hope this clarifies, CfN.  |

William Huskisson MP▸ was the first person to be killed by a train while crossing the tracks, in 1830. Many more have died in the same way since then. Don't take a chance: stop, look, listen.

Michael Crick (Channel 4 news) has just put this on twitter
Michael Crick @MichaelLCrick
Rail source tells me "technical problems for years" at Yarnton, Oxon level-crossing where man killed this pm. "I knew this would happen."
Network Rail & RAIB▸ will investigate but I really hope it is not true.
The Michael Crick article seems to say the "fault" is that the barriers stay down too long i.e preventing road vehicles from moving forward. If so then this is if anything a "fail safe". Yes, the implication of the blog seemed to be that the 'fault' means traffic is being delayed unnecessarily, thereby presumably encouraging people to take risks to avoid delay. Which is a rather strange interpretation of the 'cause' of an accident... |

(would you cross a red light at a road junction??).
Whilst it might not be the right thread to raise these comments as they may seem insenstive, for which I apologise in advance. But it sometimes that very point comes down to person driving the vehicle. In some cases a pedestrian crossing the road/railway. (appreciated we don't know the full circumstances) In some cases even both and a prime example of that happened to me yesterday, When half way across a Pedestrian Crossing showing a Green Man. (It definitely was as there were several witnesses who confirmed that) Admittedly I had committed the awful sin of walking and cellphone talking. Whilst I was certainly aware of my surroundings, I was distracted by the phone call. The traffic to the right of me had stopped and I was half way across when a Young Female Driver (I'd say late teens and no derogatory comments r.e. female drivers implied) approaching from the left side was chatting to her friend in the passenger seat. I immediately became aware of this and so did she. Sadly, it was after she'd run the red light which resulted in me becoming a temporary Honda Hood Ornament  Fortunately she was doing no more than 15 mph. On the relation to that subject I was talking to a BTP▸ Officer about Level Crossings after his colleague didn't believe the story about the Bus Driver getting stuck on the crossing. He said to me one of the worst things you can say is: "I didn't see the lights, as that's driving without due care and attention" Whilst I am certainly not implying or speculating that lack of attention was the case here. I was trying to sum up a general point of those lights and barriers are there for a reason. Also don't cross the road or railway whilst on a cellphone! |

I agree with your sentiment - this is why I posted my original in "Frequent Posters" but understand the decision to move it elsewhere |

Thanks, BerkshireBugsy. It is a very difficult decision, working out where best on this forum to place any discussion about an incident in which someone has died. However, on balance, and provided our members post appropriately, I do think it's better to conduct any discussion in the public area of this forum - where our hopefully constructive comments and suggestions can reach a wider audience. Chris. |

Chris. No problem CfN - I certainly understand. I guess maybe I am over sensitive because I live fairly near ufton nervett and go past it every day on the train. |

I know the crossing pretty well and I've always regarded it as safe provided drivers observe the signals. As one of the site's members says, level crossings are safe unless used in an unsafe manner.
If the car driver attempted to weave round the barriers then that's asking for trouble. I suppose the answer is always to install full width barriers
