To take the X12s out, you'd then end up with buses having long layovers between trips as there used to be when the 9 and 27/27a ran on their own. The 17 can't be done in an hour while running to Ingleby. 28Bs can't fit into an hour and it's not worth running it half hourly. The way it works is the most effective way.

Including the two X66/X67 branded examples, there are six MAX specification VDL Pulsars in the fleet at Stockton.

Would it not make more sense to allocate these six vehicles as first point of call, followed by the Sapphire specification VDL Pulsar, assuming it is not required for the 5/5A? That way, the premium features advertised on the X12 service would still be available, while other services it interworks with are upgraded?

It really puts Arriva at risk of customers claiming 'no quibble' money back guarantees, on the basis that they haven't had the premium features advertised on their journey.
