Let's just be clear that devolution of responsibility for and funding for core Valleys lines is taking place, and we remain absolutely committed to upgrading the core Valleys lines as part of the metro vision, so that people can have more regular journeys. Four journeys an hour, we believe, is appropriate within a metro area, as a minimum. We've been clear in stating that. We've been clear in stating that, right across Wales, there will be improvements in terms of capacity, in terms of journey times and reliability. Outside of the core Valleys lines area, responsibility for infrastructure remains with the UK Government, but we would wish to see that devolved as well, as soon as possible. I think events of the past few weeks, with the damage to flanges on railway wheelsets, demonstrate why we need to make sure that there is a greater degree of investment right across the network in Wales. And, for that reason, we believe it should be devolved—responsibility should be devolved. But in terms of the metro, I can promise Members, I can assure Members, that the bids through from two world-class operators make for compelling arguments that there will be change to the rail services within the metro area, and across the country.
