Apologies typo regarding the 34/34A.
Before 53reg examples on the WSS went into Metrolink Livery before WSS they were previously based at Chester le Street for the 34/34A, previously route numbered at the time 734.
I've been to CLS quite alot in recent weeks and I don't the 34/34A require current size bus they use. But as you said Kuyoyo more than likely it will end up with renowns along with the Waggonway 28/28A.
GNE could do what I said Temporarily until further changes later in the year. Other than been withdrawn I can't think of any other way that they could be utilised.
