Well, I spoke with a driver yesterday (who may have been wrong) but I got told that the 310 / 311 will be every 20 minutes each with the 310 route remaining the same and the 311 just running between Hadrian Park and Newcastle presumably via High Farm. The 309 will remain unchanged. So if the driver was right, here is what it could look like......

PVR: 9x
North Shields (310): 00:00
Newcastle (310): 00:47
Newcastle (311): 00:56
Hadrian Park (311): 01:22
Hadrian Park (311): 01:25
Newcastle (311): 01:57
Newcastle (310): 02:06
North Shields (310): 02:49

So working it out, Battle Hill currently has 11x GNE services per hour to Newcastle but if the above is correct, it will have 10x GNE services per hour to Newcastle with a PVR reduction of 1x. The only other thing I could think off is GNE re-routing the 309 back via the Silverlink and Willington Square / St Peter's to target more customers from the 22 and 308 but would be unlikely as that would leave Battle Hill without a service to the main part of Cobalt Business Park.
