Well, the first thing to emphasise is that the metro it not a greater Cardiff transport system. The fact that Transport for Wales will be based in Pontypridd is a sign of the commitment that we make to Valleys communities, but cross-valley links will be important. We understand that. They will be provided in the main, certainly in initial stages, by buses. We know there are many people who do look to commute across the Heads of the Valleys, and commute from one valley to the other. The railway lines that once connected those areas are long gone. That means, of course, that we need to look at how we can upgrade bus services in order to provide the connections that people need.
