The service would be disrupted, and it would be an incredible waste of resources. If I may use these crude terms, we would need either English officers to stay on trains from Carlisle to Glasgow or from Berwick to Edinburgh, or—vice versa—Scottish officers to stay on trains going south. There will have to be some kind of agreement. None of that has been taken into account. That is why we welcome the pause in the integration and the fact that all these issues will have to be looked at.
