Effectively if the 310 was made standalone with no PVR increase (11x  309/311 and 5x 310), the 308 & 309 could be timed with a common frequency on common sections of route.

As for evenings, cutting the long layover from the Tynemouth end of the 306 and adding more running time with an interworking pattern would also be a better option for Arriva. Sundays not looked at as the 308 & 309 are fairly even on Sundays.
