Thank you for that. Yes, I appreciate that work is going on and I also would like to put on record that your own office has actually been very helpful in facilitating getting the two sides together. However, I think that this is a wider problem than just Earls Court. It has come to my attention that even a station where you very helpfully weighed in about two years ago, where the volume of announcements was actually breaking your own noise pollution strategy and your stepping in did the trick then - and we are talking now about Putney Bridge station - subsequently there has been a refurbishment of that station and they are suffering all over again the same problems, which we thought we had dealt with. They are very similar to the problems at Earls Court, and I understand from my colleague Elizabeth Howlett (AM) that there are problems with Wimbledon Park. It seems that these stations that are sitting overground are now making life intolerable for residents with this new equipment. I think it is a fundamental problem which they discovered in Earls Court, but it actually goes right to the heart of the system they installed, and it turns out that London Underground did not have a clue about the fundamental problems there. So would you take it on board that this appears to be now quite a widespread problem across London?
