So GNE are well on their way to a CAZ-compliant fleet for their services that will enter the CAZ.

I think I saw a post in the Stagecoach area of the forum saying only a single-digit number of vehicles are not compliant but they’ll probably be sent off soon and replaced with Euro6 vehicles. I think that’s been said about Walkergates Depot.
Is that pretty much the case for Slatyford depot too?

And once Arriva North East take delivery of their new E400MMCs and cascade vehicles around is that them CAZ-compliant for all their CAZ routes too?

Suppose put simply my question is, are the ‘big 3’ operators pretty much ready now/will be soon?
