So, unless Go North East can offer anything better than leather seats, WiFi, Plug Sockets and the money back guarantee if a vehicle not to Sapphire standard is used on the service, then I think they might want to keep well away from Durham-Darlington.
Without trying to sound silly, what is Sapphire is it a brand or is vehicle?
