Given that Classic's Solo is a M850 and Arriva North East currently have two of those vehicles (based at Darlington - 2504 and 2505), it made sense to allocate it a fleet number close to those.
As for the identity of 7458 and others, it's not known at present.
Wonder if the Volvo B9TL/East Lancs Olympus will join?
