well looks like its was quick recovery - Victoria line reopened fully (i think they must found way to reroute the signals around the damaged area) No you can not reroute the signals, this would take days  |

Pleased to say the restoration of BEA coach MLL738 is as complete as it can be, now restoring MLL721

In the "good old day" station to station or time interval working would be initiated. But as the Vic has always been fully auto, I doubt the working instruction for that line allowed for such contingencies.

Well it will be interesting to learn just how they've restored service so quickly!

According to this it would seem that LU staff / contractors have done an amazing job it getting rid of the concrete, and presumably replacing the submerged relays. twitter.com/...2750080/photo/1twitter.com/...8766336/photo/1Of course as many railway engineer will atest, after any foolding event (even one involving concrete) you never manage to clean absolutely everything / spot ever single bit of damage and I wouldn't be surprised if over the coming weeks we get quite a few signalling issues appearing as a result. Londonstuff's edit: I've had a look to see if I could fix these but it's actually the link - maybe PB have truncated it. Sorry! |

On the old ATO system they did have station to station working on several occasions when there were long term signalling problems.

wow that's amazing - we thought its would be long work to clear them out According to some reports, workers were scouring the area looking for sugar to dump into the concrete which apparently delays or even prevents the setting! |

WOW - that's amazing - sugar did trick and saved the equipment room and even restored train back in speedy maner

Big thanks to the Technical Officers who worked in pairs through the night to get it running again.

So when the foreman shouted "Sugar" he wasn't mincing an oath!

It reminded me of a scene from Some Mothers do Ave Em... After Frank Spencer had been doing some DIY!
The speed of recovery was remarkable.
I imagine there was significant pressures from high up 'the powers that be' to get it sorted... Expensive cock-up I imagine...

Is it the taxpayer who will ultimately foot the bill for this blunder?

I suspect that some of the bill will be footed by contractor, but some amount will no doubt be from TfL. Surely the contractor would have had some drawings showing where the voids are and what the join, so either the contractor didn't look properly, or the drawings weren't sufficient for the works, and I think it will be interesting to see what the actual cause was.
Apart from Delay payout, what other costs would there be? I can only think of:
>Lost Concrete
>Delay to works (probably a week, not much in the scheme of things)
>Sugar
>Replacement Equipment
however, given how soon they had the replacement equipment on site, it seems unlikely that it had to be ordered in, it will probably have been in storage ready for maintenance or similar emergencies

Time will tell what actually went wrong. |

Although pictures do not always tell the whole story, to a layman, I found it incredible that the full Vic service was restored so quickly. I guess they had to do some testing of the electronics as well. Looks like a good example of a positive `can-do` attitude.

It is probably fortunate that it was a modern solid-state (sorry!) installation: imagine trying to find replacements for the inter-war vintage equipment which we are told is still operating at Edgware Road. |

Surely the contractor would have had some drawings showing where the voids are........... There is no doubt that those doing the work will have diligently tried not to pour concrete into the SER. They know it is there and they know how close the new escalator shaft will come to the SER. Therefore they will have put a great deal of effort into establishing what they need to do to manage the risk. It's rather like cooking fried eggs; however hard the chef tries or however experienced he or she is, occasionally some shell might get into the fried egg! Chefs try very hard not to get shell into fried eggs; the customers tend to get a little upset! |

No damage to the electronics, but a lot of relay bases, relays and wire had to be changed. |

Presumably this is a good example of why keeping a large quantity of stock is A Good Thing!
I'm assuming there will be the cost of replacing or repairing the equipment damaged - plus the bill for the staff who worked overtime all night to restore the service in the morning, who I hope received a generous rate (to be charged to the contractor who cocked up).

Yes, it actually demonstrates the need for a central stores that stores things. The last few years it has worked merely as a 'goods inwards' point on a 'Just in Time' basis.
