Select Committee on Crossrail Bill Minutes of Evidence


Examination of Witnesses (Questions 13500 - 13519)

  13500. Ms Lieven: Yes. That is fine. Could I then deal with Sir Peter's question about gate numbers to use up the bit of time before lunch. Mr Anderson, I think you are in a position to explain the different gate numbers for the different options and how they relate to the modelling.
  (Mr Anderson) Yes. I will give you the numbers we have assumed in the modelling we are about to see. For option 3 it is 21: 11 gates into the ticket hall and 10 gates out. For option 4 and the two option 5s it is similar. We have 24 gates: 11 in and 13 outbound. A combination of option 3 and option 7 together would give you 33 gates: 18 outbound and 15 inbound.

  13501. Chairman: We will adjourn now and resume at 12.30.

  After the short adjournment

  The Legion model CD was shown

  13502. Ms Lieven: Mr Anderson, that has dealt with how the various options performed. Can you tell us what you perceive the benefits of the various options to be in passenger terms.
  (Mr Anderson) There were two types of benefit: firstly relief in congestion that could occur around the gateline in ticket hall B—and I think all the options do that to a degree. Our calculations, which I think we put in an exhibit, suggest the relief there was broadly similar throughout the options. There is then a second category of option which is for those options to provide a direct access to street level. There is a journey time saving in addition to the saving of queuing at the gateline. That is option 5A and option 7, which give a more direct route to street. We have, indicatively, taking those time savings and using rather more economic parameters, converted them into pound notes. Exhibit 4 shows that.[40] The congestion relief benefits tend to be similar: the more gates you put in, the more relief you get. Option 4 will perform better than option 3 and the figures indicate that. We get of the order of £30 million of benefits throughout each of the options for congestion relief. With 5A we see a quite significant increase and with option 7 a significant increase. Those increases are down to the more direct route that people can take to street level with those options, because they have, in the case of 5A, new escalators directly from the old ticket hall, and in the case of option 7 from the new ticket hall up to Liverpool Street itself. Those will broadly be the benefits for the various options. It seems that we get good congestion relief benefits from option 3. We get a little bit more with option 4 and probably a bit more with option 7. The big difference comes with option 5A and option 7 in terms of journey time savings.


  13503. Finally, can you conclude on your view, primarily, of option 3 in passenger terms.
  (Mr Anderson) Option 3 provides significant relief to the gateline in ticket hall B and the benefits are the indicative benefits that are shown there. It does that quite satisfactorily in 2016 and for the period into the future. I think we saw on the animation that we get some queues at the very busiest times in the 2076 case but overall we have an acceptable solution there in terms of relieving the gateline.

  13504. Ms Lieven: Thank you very much. I have no further questions of Mr Anderson.

  Cross-examined by Mr Laurence

  13505. Mr Laurence: Good afternoon, Mr Anderson. Was there a reason why you did not show option 4C.
  (Mr Anderson) There is no reason at all, other than time and illustration.

  13506. Ms Lieven: Sir, I am sorry, I should have made clear. We do not argue that option 4C does not perform plus 35 per cent, so we did not see any need to show it. We were not asked in advance to show it, but we can do so if anybody wants us to.
  (Mr Anderson) It is available if the Committee would like to see it.

  13507. Chairman: If we are provided with a CD, then it may be put together with that so that we can view it.

  13508. Ms Lieven: Certainly, sir.

  13509. Mr Laurence: I do not think we knew until this morning that it was going to be shown at all.

  13510. Chairman: Until this morning, we did not realise we were going to have two packs or that the letter had not arrived. It happens.

  13511. Mr Laurence: Mr Anderson, I would like to check one or two things with you and then go into one or two things in a little more detail. Do you accept, with Mr Berryman, that if there is to be amendment to the Bill—and I appreciate that you contend there need not be an amendment to the Bill—now is the time to make that amendment? In other words, before the summer recess is when you will want to know what the Committee's decision is.
  (Mr Anderson) Yes.

  13512. If 3B is rejected by the Committee, we are necessarily into considering either 3B with 7 at some later stage—which of course is suggested—or some other alternative altogether.
  (Mr Anderson) Yes. I think Mr Berryman gave the answers to those questions.

  13513. If 3B plus 7 later is rejected by the Committee, the contest, as you see it, is between 4C and 7A. Is that right?
  (Mr Anderson) I am not sure I have looked at it in those terms.

  13514. Would you mind doing so now, to assist the Committee.
  (Mr Anderson) I can only really advise on the passenger modelling of benefits associated with those various options and that is the information we have on the chart there. It would suggest in passenger terms that some of the other options are better than 4C.

  13515. Although the decision will be taken by somebody other than yourself, your present inclination would be to say that in the scenario that I have just put to you it is 7 that there will be promoted now rather than 4C. 7A rather than 4C.
  (Mr Anderson) If there is a choice between those two, obviously in passenger benefit terms that has to be my preference.

  13516. Are you giving that evidence on the footing, as I think you confirmed, that 3B would be done in any event or that 7A would be done independently of 3B?
  (Mr Anderson) My view is that option 3 is worth doing first and should be done first, and indeed that is our position. If you did option 7 alone, in passenger modelling terms, by the time you get to 2,076 and you add 35 per cent, you would probably have to do something in the existing ticket hall anyway, so my preference would be 3 first.

  13517. You did not quite follow what I was putting to you. If we are into a scenario where the Committee is, in effect, being asked to decide between 4C and 7A—make that assumption in our favour—are you saying to the Committee that if you were driven to that position you would want to do 3B at the same time as doing 7A or whether under those circumstances you would do just 7A at the beginning and something like 3B later?
  (Mr Anderson) It would be the other way around. We would not necessarily do them at the same time. I would obviously defer to Mr Berryman in relation to phasing works of that sort. My preference would be for 3 because of the benefits that brings with relatively little disruption.

  13518. I know that is your preference, but, if the Committee take the view that is a solution that is ruled out, 3B now with something like 7 later, and want something definitely more radical, such as 4C and 8A—which is what we are asking for—and it may be that you have not thought about this, and I am not meaning to be unfair to you—in that event, the additional provision you would be promoting would be 7A on the evidence you have been giving. Would you be doing 3B as well at that time or not? I think you modelled it on the footing that it would be 7A and 3B together.
  (Mr Anderson) Yes, I am saying that you would not necessarily need to do them at the same time.

  13519. If you were compelled to do 7A at the beginning, would you do 3B at the beginning as well or not?
  (Mr Anderson) I am not sure I could make a decision on that right now. I think that would be a matter for discussion with London Underground and others.
