To be honest, if Nexus/GNE/Arriva got services streamlined & cleaned up, the 51 (at least Wiltshire Drive) and 41/41A extension could at least be hoovered up by "big buses" leading into stable and profitable common corridors. But that's another debate.

As for the 51, I can see something like:

- 310 via Wiltshire Drive (309 also changed to serve High Farm) - part of rumoured Coast Road clean up with all 30x's runing every 20 mins each.

- 22 split 1x every 20 mins to Hadrian Park / 1x every 20 mins to Cobalt. This would replace the 311 and aleviate the need for the 310 to serve Hadrian Park.

- 1x 55 per hour extended to Whitley Bay via 51 route after Palmersville & Holystone.
