Some lines will be electrified first. The business case for others will be looked at in the future. We can't electrify them all at once. We're looking at the lines and developing electrification as time goes on.

But the point that Plaid Cymru are trying to make is this: that somehow—I know they're not listening—there has been a move away from providing people in the south Wales metro area with a better train service. That's not the case. The trains will be better, more frequent. In the first phases, some will be electrified, and there will be a rolling programme for doing that. People will be able to catch buses that connect with train services. They will be part of an integrated network in a way that's never been possible before. The metro will happen. It will move forward along the lines we've suggested, along the plans that we've suggested, and the people in the south Wales metro area will get a better service.
