Presiding Officer, I think that the First Minister did answer some of these questions during his exchange with the leader of Plaid Cymru this afternoon. But, just to repeat, the stock to which Leanne Wood refers will be phased out early in the new year. They're being kept on the lines at the moment to maintain capacity. And, of course, there are rolling stock across the whole of the UK; this isn't an issue which is particularly confined to Wales. And the First Minister also set out the future proposals in terms of the reduction of fares across Wales as well.
