7501-4 were all branded for the X93 for a couple of years, having previously been on the 308 at Blyth and a brief spell at Ashington. They were then refurbished into Sapphire with 7505-9. 

7507/8 were branded for the Alnwick/Berwick routes, however all of 7505-9 frequently saw use on those routes in their time at Ashington.
