Looks good & UnCluttered (compared to previous branding and many GNE brands) Could be a nice template for future brands to develop a semi-corporate style, which Go North East lacks. For Example: Keep the rear swoop on a limited number of base colours (although I would prefer one corporate) but only change name "Centurion" "Diamond" etc... with corresponding symbol replacing the torch seen on Centurion. I would have dropped the "The" and simply branded "Centurion"
Who knows! It could even be adopted for Nexus (or whatever brand they want to use when QCS comes into operation)
