So, if I follow the First Minister, what I think he's saying is that the reason for the extension of the use of the Pacer trains—it's not just a legacy of the last franchise, it's a consequence of some of the procurement decisions and the problems with that made under this one. Now, can you confirm that Arriva ordered four to five-car Flex trains, as I think they're called, and that Transport for Wales extended that order to nine trains? Can you confirm whether or not these electric trains with a diesel engine that are on order actually work or not? And, if they don't, has Transport for Wales built in any penalty clauses to the deal with the supplier, Porterbrook trains, and is there a cancellation point that gives Transport for Wales the option of pulling the plug on that deal? And have Transport for Wales and the Government made any analysis of the cost implications of having to keep these older Pacer trains in service in relation to the maintenance costs?
