On another note, I've done some messing around on MS Excel working how the evening 308 & 309 could be better coordinated throughout as currently, there's a 45 minute gap and with the exception of the two last journeys of the night, no even (or relatively even) headway at each side of the hour.

The following would do exactly that whilst keeping both Arriva's & GNE's working patterns pretty much the same and no PVR increases.

Arriva:
- Evening 306 & 308 journeys re-timed to operate 5 minutes later.

- Evening & Sunday X10 & X11 journeys re-timed to operate 5 minutes later (note that evening X10/X11 now interworks with 306)


Go North East:
- With the exception of a small number of late evening 307 journeys, no changes to departures ex Blyth or North Shields.

- Evening 307 & 309 journeys re-timed to operate 10 minutes later ex Newcastle.

- Last 309 journey ex Newcastle operates 5 minutes later departing at 2350.

- Last 307 journeys depart North Shields at 2140 (re-timed by two minutes between North Shields & Hadrian Park), 2255 and 2355.


So departures would work as follows:
308 & 309 ex Blyth - xx:19 & xx:50
308 & 309 arr Newcastle - xx:15 & xx:55
308 & 309 ex Newcastle - xx:20 & xx:40
308 & 309 arr Blyth - xx:14 & xx:42

All services ex Haymarket:
307 - xx:10
308 - xx:20
309 - xx:40
306 - xx:50
