Otherwise either Stockton or Darlington would have had to lose out on 3 Pulsars as an additional 3 would have to have been refurbished in addition to 1479/1524-33 and the timetable and running boards reworked to move the effected school work (865 is certainly one of them, one of our Arriva insiders will be able to answer what routes) which of course may have saw Durham's PVR increase anyway to cover the additional separate school boards.
My bad I didn't know about the School Runs, But even though it would give the brand a worse look, The B7s would cope more with the 6 than the X20 if refurbished to Sapphire spec like Leicester's B7s that could fill a gap for the E400s?
