The new timetables are now on Traveline North East. It seems one X30 or X31 an hour continue to Consett and continues until after 10 pm from Newcastle to Stanley. Late X30 seem to link in with 78A to continue journey (at least last one does). I suspect this is more about transporting drivers between Consett and Stanley.
6A reduced to hourly on an evening and last bus is at 23.10, not 23.15. M6 is now Lanchester to Metrocentre, with seemingly no 30 or 30A. M8 is retimed but not too different. Pattern of M6 / M6 / M8 towards Stanley. M7 is truncated to East Stanley Circular.
X70 now operates two hours later into the evening.
Most 45s / 46s become X45s / X46s except for 45E journeys, now just 45s. Last bus leaves Newcastle at 23.23, two minutes earlier.
From something I saw a while back, 15 becomes X15 and 15A becomes X5. I'm not sure of effect on timings.
I'll leave it to others to work out rest.
