I haven't looked at timetables, so no idea if it will work.
M2
Current 30min frequency between Heworth and Ayton.
M3
Current 30min frequency between Heworth and Birtley - operating into Birtley as M2 route (Vigo, Portmeads) and out via M3 (Durham Rd, Vigo Lane) route. It doesn't operate via Rickleton.
8
Current 30min frequency - diverted via Birtley, Fell Bank, Portmeads and then current route from Rickleton.
The current clockwise/anticlockwise route from Birtley to.Washington is maintained, along with the 15 min frequency to/from Birtley town centre.
