Select Committee on Crossrail Bill Minutes of Evidence


Examination of Witnesses (Questions 16660 - 16679)

  16660. Chairman: You have mentioned there that no matter how much use is made of floating slab track, it is not going to make a difference, yet item 3 of the Petition is asking specifically for the use of floating slab.

   (Mr Winbourne) I think, with respect, sir, in this case what I am saying is that floating slab track should be a given anyway, unless you are going under roads and parks where there is no one to bother and if they can vary it and save money, okay, but under offices, houses, shops, wherever people happen to be, I think there should be floating slab track as a given, number one. Number two, I have direct experience of building in Southwark which the Committee can visit and see the cracks and feel the vibrations. That building is still standing and I referred to it in my previous evidence. What happened there was that compensation grouting quite obviously connected vibrations not from the Jubilee Line in that case, but it was after the shockwave of the Jubilee Line went through and so on and the grouting started that they connected the main line to the building when the vibrations started right away from the main line long before the Jubilee Line was finished. If you get physical connection, this is what happens and that building shuddered and shook and as a result became useless for its purpose as a recording studio. We are dealing with Mr Payne, but I have seen evidence previously about recording studios and it has all been fudged. You are probably going to hear some more, I am informed, later from people in Soho, so it is possible I might be back.

  16661. I am not quite sure if that is a yes or a no.

   (Mr Winbourne) Yes, the answer is by all means it should be there if you are going under residential areas anyway, but I very much doubt whether it will be enough for Mr Payne's building for all the reasons I have given.

  16662. Mr Payne: Just because of the size of this tunnel and the concrete that surrounds it.

  16663. Chairman: I just found it unusual that you should be petitioning for floating slabs and then criticising their use in your Petition.

   (Mr Winbourne) Sir, can I answer that straightaway. Mr Payne wrote his Petition long before he came to me.

  16664. Mr Payne: I have very little left now, sir. Have we finished, Mr Winbourne?

   (Mr Winbourne) Yes, as far as I am concerned, unless there are any questions anyone wants to ask.

  The witness withdrew

  16665. Mr Payne: There has been very little consultation on alternative alignments. Mr Norman Winbourne's Cavendish Square option should be properly considered. The evidence suggests that there are problems concerning noise and vibration from other recent schemes, such as the Channel Tunnel Rail Link and the Jubilee Line Extension. I am used to some noise from the much smaller Central Line and, therefore, I seek an undertaking that the Promoters utilise the most modern form of floating slab track. Reliant on avoiding the social costs this puts on Westminster City Council and local amenity groups, my experience has found them lacking and, therefore, my faith is not entirely with them. Crossrail is to be a 24/7 rail link. Currently the only sound which may possibly wake my slumbers is the sound of the nightingales in the gardens that surround. This puts a heavy responsibility on the Select Committee to make the right recommendations. Thank you for listening to my humble Petition and this concludes my submissions.

  16666. Mr Mould: Sir, insofar as noise and vibration are concerned, in contrast to the Central Line which is a rigidly fastened track system, as you have heard from Mr Thornely-Taylor, the proposed construction techniques in relation to the Crossrail railway beneath the surface are to up-to-date, modern standards and the expectation is that deploying those standards, including where necessary floating slab track, will achieve a noise environment within residential and other properties at the surface over the railway which we predict to be acceptable. We are not, I should say, proposing at this stage that it would be necessary to install floating slab track at this location because our predictions do not justify deploying that technique, but, as we have made clear in evidence to the Committee, in any location where the standard system that we propose is predicted during the detailed design causing levels of groundborne noise exceeding the relevant assessment criteria of 40dB(A)LAmax,S, an enhanced track support system will be installed, so that is the approach that we are taking, of which the Committee is well aware from the evidence of Mr Thornely-Taylor. We have explained that we have assessed the propensity for disturbance due to vibration due to the operation of the underground railway and Mr Thornely-Taylor has given evidence in relation to that. Suffice to say that our assessment has shown that that is not predicted to give rise to disturbance or substantial impact to those residing at the surface over the running tunnels.

  16667. Turning briefly to settlement, if I can cut through what you have heard about that, you have been shown at page 7, I think it is, of the Petitioner's exhibits an extract from the Listed buildings assessment carried out by our consulting engineers in relation to the Petitioner's properties.[32] That is in accordance with the settlement policy and process, of which you have heard a great deal of evidence during the course of these hearings, and you see from that that the prediction from that assessment is that the building in question will not suffer any appreciable damage. Cutting through the point, the Petitioner's company is entitled to call for a settlement deed under our policy and, as part of that process, it will be open to the Petitioner through his advisers, if he chooses to do so and wishes to do so, to make representations to us in relation to the assessments which have been carried out and, with that point having been made, I do not propose to take the Committee's time correcting some of the factual areas which have been put forward in relation to the assessment carried out thus far. It seems to me that is better dealt with through that process rather than troubling the Committee with that at this stage. Those, I think, are the points which have been raised in relation to the Petitioner's property itself.


  16668. In relation to the other matters, suffice to say that the Committee has heard evidence from Mr Berryman in response to the Residents' Association of Mayfair Petition on Day 24 in relation to the consideration of alternative alignments. Mr Berryman dealt with, amongst other things, Cavendish Square at paragraphs 6787 to 6794 and, in summing up our position, Ms Lieven dealt with the matter at paragraph 6853 and it may just be helpful to remind the Committee that what we said was, "So far as our consideration of alternatives is concerned, we have over the past years considered alternatives in very considerable detail and at the end of the day it comes down to a professional appraisal that the alternative schemes do not provide sufficient additional benefits, and in most cases provide no additional benefit and, indeed, additional disbenefit. In particular, they do not relieve the overcrowding on the Central Line, they produced other problems on other lines . . . " and so on. I will not bore the Committee any further by repeating matters, but those are the points I wish to make in relation to that.

  16669. Kelvin Hopkins: I have a question or two on the floating slab track. I can well believe that Crossrail will be far less noisy than the Tube lines, particularly the old, cut-and-cover, rattling Circle Line and so on, but nevertheless it is going relatively close to particularly a basement or lower ground-floor flat. Would it not be reasonable to err on the side of generosity to residents by putting in a floating slab track whenever it goes clearly close to where people are living rather than trying to trim, because I know that there is a cost to incur, but to trim the cost which, compared with the overall cost of the project, is fairly small, but putting in floating slab track erring, as I say, on the generous side to residents in this particular case rather than having to fit retrospectively following complaints or whatever which might be much more difficult? It may be a technical question which is better addressed to Mr Berryman rather than to yourself.

  16670. Mr Mould: Well, Mr Berryman, as is his wont, has been whispering in our ear and it may be sensible if I do ask him to deal with that. Yes, he has said what I thought he might. The point is that we do not judge there to be any material benefit from taking the line that you have suggested and I think Mr Thornely-Taylor has explained to the Committee that the approach we take is that we have a design criterion which is what it will be designed and maintained to which is, as you know, 40dB(A)LAmax. Achieving that, and in the case of this Petitioner predicting to achieve well below that, by an appropriate form of track design will actually produce an environment that is, on experience, acceptable. That being the case, and as we expect to be able to achieve that without the need to resort to the cost and increased maintenance liabilities associated with the installation of floating slab track, it simply is not, we say, justified. Using the more conventional methods that we are proposing will achieve an environment that is, objectively viewed, acceptable for this and other residents in the vicinity, so it is just not a valuable additional design step for us to take. That is our answer to that point.

  16671. Chairman: Thank you very much. Mr Payne, the last word?

  16672. Mr Payne: I just think that I and my expert witness have shown that there are some doubts as to the tunnel which is about four times as big as a small tunnel and even though the Central Line is very old and it is built on old, wooden foundations and that Crossrail will have a smooth track and all the rest of it, it is just the size and looking at the physical size of it and the evidence, I just feel that Crossrail feel that maybe they will recalculate later and fine-tune. At the end of the day, for the residents trying to sleep at night, trying maybe to run a business from home or whatever, really there are going to be some very big social costs. I just have no faith in the current specification they have provided. Thank you.

  16673. Chairman: That concludes the hearing on that Petition. We now move to Petition Number 91 of the Open Spaces Society and the Ramblers Association.



The Petition of the Open Spaces Society and the Ramblers Association.

Mr Eugene Suggett appeared as Agent.

  16674. Chairman: First of all, I have got the wrong representative on my list.

  16675. Mr Suggett: Thank you, sir. Yes, I was going to say something about Mr Selwyn's absence in a moment.

  16676. Chairman: Ms Lieven?

  16677. Ms Lieven: Sir, I think it might be helpful to the Committee if I made a quick opening because this is a totally different issue on a different bit of the route. The Open Spaces Society and the Ramblers, as I understand it, appear effectively on one issue. They may have a few more general points to make, but there is one substantive issue before the Committee which concerns what is called Dog Kennel Bridge which is a bridge on the western section of the route. Perhaps Mr Fry could put up on the scanner a map.[33] It is an area of the route the Committee, I think, has not spent much time on. Dog Kennel Bridge is a bridge which is not a road bridge and it lies between, it is difficult to see on this map, Iver Station and Taplow Station and the motorway is the M25, just so the Committee has some kind of sense of the geography of this. In respect of Dog Kennel Bridge, the Bill scheme is to demolish the bridge and not reprovide a bridge. In all other cases where a bridge is to be demolished, it is reprovided. There have been two issues about Dog Kennel Bridge.


  16678. Firstly, it is one of a number of bridges which were originally designed by Isambard Kingdom Brunel which have been known generically through the project as the `Brunel bridges', four of which the Committee may have realised were Listed by English Heritage in April 2006. Dog Kennel is one of the Listed bridges. That is one aspect.

  16679. The other aspect is that of pedestrian access. So far as the Listed building issue is concerned, there have been very extensive discussions, which the Committee happily has not had to be involved in at all, between ourselves and English Heritage as to how to approach these bridges because, as Mr Berryman will explain, the reason that Dog Kennel Bridge has to be demolished is to provide the overhead electrification on the Great Western Line with sufficient clearances. There has been, as I said, very considerable discussion and engineering input with English Heritage and an agreement has been reached with English Heritage by which two of the four Listed buildings can be saved and two of the four still have to be demolished. There are two non-Listed Brunel bridges which can also be saved. English Heritage are happy with that decision and have indicated so quite clearly in writing and, I have to say, it has been a position that has been reached after many meetings and much discussion. This is not something that English Heritage has come to lightly. Buckinghamshire County Council also raised the issue of keeping Dog Kennel Bridge and decided not to appear before the Committee after English Heritage agreed the position with the Promoter. Sir, so far as heritage issues are concerned, they have effectively been agreed with those bodies which are primarily concerned with them.
