New buses should be spread out fairly to each different operator, Sunderland & Teesside have had old fleets for a long time until recently. And with DDA deadline coming for single deckers, along with the darts nearly passing their use by date, Stagecoach will care more for those problems then replacing buses that are coping well enough (mid life enviros). I can see Newcastle getting new deckers next year, so the 07 reg ones can move on to depots like Teesside for schoolars and saturday service.
