Select Committee on Crossrail Bill Minutes of Evidence


Examination of Witnesses (Questions 8360 - 8379)

  8360. It may be said to you that that is not the matter before this Committee, because options 2 and 3 only run from Paddington and not from Maidenhead. Does that make a difference to the point?
  (Mr Hardie) It might make a slight difference but I do not think, in the large scale of things, that changes to the west of Paddington will greatly influence what is happening in the south-east of London and North Kent. That could only be confirmed by more modelling, and we did not have that modelling at our disposal.

  8361. So if we turn on to page 33 (again an extract from the Montague Report) and Option 2, whole life net costs, what benefit to cost ratio does that come out with?[34]

  (Mr Hardie) This comes out with a ratio of 1.41:1.

  8362. Option 3, on the next page, 34?[35]

  (Mr Hardie) This is the extension beyond Abbey Wood to Ebbsfleet and it shows that the benefit cost ratio for the project as a whole rises from 1.41 to 1.46:1.

  8363. So an improvement as a result of the extension from Abbey Wood to Ebbsfleet?
  (Mr Hardie) That is right, yes.

  8364. Then, on page 35, I think there is a correction to the bottom of your note. Is that right?[36]

  (Mr Hardie) The bundle does have the correction in it. To be clear, the double-starred note at the bottom should say: "Slide 38 shows that £268 million included only £83 million of initial capital cost". The emphasis is it should be £268 million.

  8365. Let us go back to the substantive point in paragraph 275. What are the points that you are drawing attention to in paragraph 275 of the Montague Report?
  (Mr Hardie) First of all, is the comment from the Montague Report itself which described £268 million as a "modest incremental cost". The second thing is that for that modest incremental cost one had an incremental benefit cost ratio of 3.21:1. The other point I would like to make out of it is that the £268 million of net incremental costs referred to in the Montague Report does, of course, include a host of future operating and maintenance costs and other tax losses etc, which were bundled up into the present value. I thought what was quite significant within that figure was that in terms of an actual increase in project cost the figure was only £83 million of initial capital cost.

  8366. Montague notes (if I can just ask you about the third sentence): "Extension to Ebbsfleet would also support the regeneration of the Thames Gateway." Is that a separate point which is dealt with by the next witness?
  (Mr Hardie) Yes. I have not referred to it myself for that reason.

  8367. Page 36, paragraph 31 of the Montague Report.[37] What is it that you wish to draw to the Committee's attention from this extract?

  (Mr Hardie) I felt we could not ignore the traction notices around the rolling stock and that in terms of assessing our own view of the project we should take that into account. What the Montague Report did not do was identify what additional costs there would be in terms of creating from the start a class of rolling stock which had dual voltage. He did point out that the case should perhaps be reviewed in that light. I think we believe it is an important issue because if Crossrail is to go to Ebbsfleet in the long term, and for any part of that route, were the third rail to be continued, then stock must be capable of operating over it, in which case the stock should be designed right from the beginning for that purpose. Otherwise, retrospective adjustment to the stock would be very much more expensive.

  8368. You say on page 37 that the extra cost of dual voltage trains is not great if specified from the outset.[38] You say it is not unusual and it is not cutting edge technology.

  (Mr Hardie) That is right. Certainly dual voltage stock exists at the moment and while I cannot put a price on the marginal cost of including it at the beginning, certainly if it is specified at the beginning and the designers know that from the start, then the stock can be designed in such a way that the equipment is either on board right from the beginning or perhaps some sort of passive provision is made to allow the inclusion of the DC equipment at a later date.

  8369. An example of a line where dual voltage stock is used would be?
  (Mr Hardie) Thameslink. It is quite a normal operation to change power supply in the course of operation.

  8370. Mr Cameron: One of the points made by Mr Elvin in opening was that an advantage of going to Abbey Wood and stopping there was that Crossrail could be served by overhead lines and not by the third rail.

  8371. Mr Elvin: I think I can cut this short and say to the Committee that I am told I can give an undertaking that the rolling stock will make passive provision for dual voltage so that there will not be any prejudice caused.

  8372. Sir Peter Soulsby: That is very helpful.

  8373. Mr Cameron: I am grateful for that. So we can go to the third point on page 37. What is that third point that you are seeking to make?
  (Mr Hardie) If the trains go beyond Abbey Wood towards Ebbsfleet then they have to pass Slade Green depot, and it could be a very convenient place in which to stable certainly some of the trains that serve that branch, and it would also perhaps then allow some of the trains that might otherwise have been stabled at Romford to be stabled at Slade Green and, in this way, some of the concerns about the operation of Romford depot might also be relieved. I have not worked out a complete service plan for that.

  8374. We can go to your page 38.[39] There I think you explain how the Montague Report arrives at the benefit to cost ratio of 3.21:1 for the extension to Ebbsfleet.

  (Mr Hardie) Yes, what I have pointed out is that I have got three columns of figures there The first column, which I have called "Abbey Wood (Option 2)" is actually presented in the Montague Report, as is the middle column "Ebbsfleet (Option 3)". However, in the third column I have had to deduce those figures and come back to recreate the benefit cost ratio of 3.21:1 that the Montague Report quoted. It is a straightforward matter of addition and subtraction.

  8375. For example—I am not going to go through them all—row one, "capital costs" you get the £83 million by deducting the figure for Option 2 from the figure for Option 3.
  (Mr Hardie) Yes, that is right.

  8376. And the 3.21:1, of course, is not your figure; it is the Montague figure that we looked at on page 35.
  (Mr Hardie) That is right.

  8377. You then take it further by considering costs not accounted for in Montague. Can you take us through your next few slides to explain the exercise that you carried out?
  (Mr Hardie) Certainly. There were two sources of information which set out where the costs assumed in the Montague Report were insufficient. First is in the CLRL's letter to Bexley Council of 26 January this year, where it says that a design study carried out in 2002 suggested that a proposal to widen the railway would cost £67 million, and that this figure could rise to £90 million when risks are incorporated. It pointed out that this figure made no allowance for railway systems and land purchases. The second point comes from the Montague Report itself where it pointed out that on the provision of a station of Ebbsfleet, it had been assumed the costs would be borne by developers.[40] So, to take those two sources to the next slide, which is slide 40, I have taken the most pessimistic figure of £90 million for providing the four-tracking.[41] I have started with the £83 million which comes from the Montague Report, I have then added in the £90 million which is the CLRL figure—the most pessimistic one—for putting in the four-tracking; I have then assumed a further £10 million costs for land purchases and the railway systems and then a further £10 million for the provision of a station at Ebbsfleet. Collectively, instead of the £83 million that was in Montague I have now come up with a figure of £193 million.



  8378. On page 41 you put the £193 million figure in and it comes out with a benefit to cost ratio of 2.27:1.
  (Mr Hardie) That is right.

  8379. Can you just remind us of the Department for Transport's guidance on appraisal of schemes? Benefit cost ratios of two or more indicate what?
  (Mr Hardie) A high return.
