I thank all noble Lords who contributed to this brief debate. I expected to be vilified and attacked, and that all happened in due order. I have no comments to make on that—it goes with the burden of trying to stand up for things that you believe in. At least my noble friend withdrew the idea that I might be hysterical, which was only marginally worse than getting a low 2.2 for drafting when we introduced the discussions on the higher education Bill a few weeks ago.
I had a good response from the Minister on the particular questions I raised, and I thank him for that. On whether the statutory duties required under the CROW Act had been dealt with, he said he thought that they had been published. I would be grateful if we could perhaps have a further discussion on that when I have seen the letter that he will write. My impression was that they were not spelled out in the detail that I
am looking for. I am sure that we will get to that point, so I am not worried. I look forward to corresponding with him on that.
The second point is on the cost of tunnelling, a question that came up several times from noble Lords. I understand the point that has been made but, as was said, I think, by the noble Baroness, Lady Pidding, to know the cost of building the whole railway is important, but it is not the only factor that we need to know. What savings have been built into the overall cost by not doing other things that would have cost more money or, indeed, less? It is that argument that we are lacking information about. If it is true that the tunnelling is providing environmental benefits, those benefits need to be taken into account in the total value for money—a point that was made. It is that issue that we do not get.
For instance, my noble friend Lord Young raised the issue of the Colne Valley, which was not part of the amendments I put down, although it could have been. He said, as has been said elsewhere, that this was independently assessed and so is okay. But when you learn that the independent assessor was a non-executive director of the Department for Transport, which authorised the review, you wonder whether that is truly independent. Again, the point is: what does that show us? If the figures provided by the promoter are correct, that is one aspect, and it is very useful. But it does not tell you what would have been the cost had it been done a different way, such as by tunnelling. If you do not cost in the environmental benefits, that is an issue.
The Minister mentioned a range of costs for different tunnels. The figure that we most often hear, and therefore the one we are using, is about £485 million—I do not want to go into this in any detail—for the extension of the tunnel from where it comes out in the AONB in the Chilterns to Wendover. It is that figure that I want to measure against the savings that would occur from the environmental benefits preserved—the lack of building of viaducts and the requirement not to build bunds and sound-proofing. That is the figure we never hear.
Lots of people who have been engaged in the process say that they have read the reports and seen the figures. They always say that it is okay, but they never tell us what the figures are. Do noble Lords not find that just a little odd? That is why I say that the public interest needs to be satisfied and why I put down these amendments. However, I am satisfied that we have had the debate that I wanted to have at this stage. I look forward to the letters from the Minister and, with that, I beg leave to withdraw the amendment.
