We've heard from witnesses who have suggested that there is shrink wrap technology available right now for braking systems on trains. It's off-the-shelf technology. It's a question of retrofitting existing rolling stock. This would go a huge distance in, for example, minimizing noise.
I know you're not suggesting that this kind of move to best available technology ought to be delayed, that we should have dispute resolution first and then delay the retrofitting of that stock to later. As I understand it, you're not suggesting that, right?
