See I would spin this service on the head.

I would re-introduce the service 311 and create it as an express service

Newcastle - Corner House -CHILLINGHAM Road Roundabout then express to chicken Road ramp area but direct then every stop through battlehill then a bizarre loop along to the B&Q roundabout where the Police station and Wallsend pub is loop round the roundabout then head up to hadrian Park and do the loop

This random loop is key ( it's about 1min added journey at present it's worth it)

We have then created an express route and dealt with Hadrian Park

307 doesn't go round the the loop at haridan Park and becomes an express except at night
Every bus 306 307 308 309 (311 example service) serves the link to serve police station B&Q Wallsend pub

We then create a mini hub/bus station to interlink with services

It also means using the 311 service it can create an express service but act as a feeder service to reuglate a later running service eg...

A 311 service could have the driver say anyone want the 308 service is to board this bus we will meet the bus at battlehill for your onward journey (the 308 could even terminate at Chillingham Road and meet the service

The purpose of the 311 is to create an express service but also a service to regulate a late service
