Mr. Barry Kenny:

The business case will assess all costs. Ultimately, in all circumstances we are speaking about a new track bed and new track, whether it is on the ground, as it is now, or it is with a greenway. As I said earlier, if, ultimately, there is an ambition for both and it is something that local authorities want to pursue we will be very happy to engage with the local authorities on it. The delivery of a greenway alongside a railway would be a project for the local authorities to progress. We would definitely work with them in this context to facilitate it. Dual delivery for a project would be more efficient.
