I came to the same conclusion about the A1 & M1 now interworking. Shame about the reduction in journeys on service M1 though as it did sometimes pick up a few passengers on the way to Thropton, although not many, no clue on the other runs.
Nexus must have got those timetables done quick, VOSA only received the registration changes on November 2nd. Old timetables still on PCL's website and still no A1 timetable.
