I’ll answer this one for myself. I hadn’t done that, but now I know it exists then I might just do that. XC just seems to be first in line for comments as there is so much that needs commenting on!
Reality is, all we've got is an initial concept livery design, it will almost certainly be altered before any paint is ordered and trains need painting now as part of routine overhaul and maintenance, putting them into a base livery may have some merit, but that is assuming any future livery is set in stone.
This refurb has probably been planned with supplies ordered before the GBR branding was conceived.
XC Have more than their fare share of faults, but the last few posts go to show how much people jump on the bandwagon when it comes to criticizing XC while ignoring other TOC's that are doing exactly the same.
