Not necessarily.
Vehicles of different lengths have different a different shell life span, and the business plan which went with the investment of that batch of vehicles would have covered the costs over that amount of time.
It is obviously quite possible that these vehicles won't even last that length of time in the fleet also! It does seem that Go North East are wanting to reduce their average fleet age.
Ultimately depends how much money the services make which they have been allocated to, and how much money the services make when the vehicles eventually cascade down to other services.
