Yes, of course. An extendability framework is now being established for the south Wales metro. I'm looking at corridors that can be enhanced in the future. Of course, I don't really need to rehearse the figures—11 per cent of track, 11 per cent of stations, 20 per cent of level crossings in Wales on the Wales route, and yet we've only received about 2 per cent of investment from the UK Government. Clearly, if we are to improve speeds and reduce journey times, and improve the regularity of services across not just the south Wales lines and services, but also elsewhere in Wales, then we need to see further investment. 

I have met very recently with the leader of Bridgend council to discuss Pencoed. I was accompanied by the local Member, and we have asked the council to bring forward proposals that we will be able to, in turn, promote to UK Government for investment. I think it's worth saying that the commitment that TfW has to increasing capacity is one part of the jigsaw. In order to increase and improve capacity we also need to see investment in rail lines, the track and the signalling, which then can enable increased capacity on the network at any given time.
