And where has it been stated that 4664 will be branded for the X16!? All that has been stated is 4664 is being refurbished to MAX standard rather than pigeon-holing it into Cross Pennie Livery when it is to be the spare! By having it MAX means if not needed on the 685, it can be used elsewhere without people complaining that it is off-route. And if needed, it can cover on the X16 yes but it won't be branded for the X16.
