These are issues that are being considered as part of the process. It’s right to say that, certainly in the future, we will be looking at light rail in terms of providing new services. It’s easy to do that than through heavy rail. And, of course, we’re examining very carefully what the most effective way of providing rail services will be in the future. I do emphasise that whatever model is chosen for any particular line, the terms and conditions of those working in the railway service will, of course, be protected.
