I'd say the B7TLs are more urgent to replace than 7501-09.

I'm not sure how much the X20 would justify brand new vehicles. Also, the '6 or 7' new vehicles has me stumped, as the only routes Ashington have that fit that perfectly are the X18 or the 35. The 35 has 3 vehicles that are only 2 years old, so would only need another 3, and I'm not sure they need to replace 7529-33 on the X18 for a good few years yet.

7529-33 to the X20 could be a possibility, if the X18 receives another 6 brand new vehicles. Or, 4 new E400's for the X15, with 7511-4 going onto the X20.
