Nexus tender opportunities from September 2016 reveal some of Go North East's planned service changes, which have been rumoured for the past few weeks.
Service 17 is withdrawn and replaced by new services 11 and 42, and revised services 40/41.
New service 11 replaces the link between Wallsend and Whitley Bay, revised services 40/41 replace the link to Holy Cross, and new service 42 (replaces service 80) replaces the link between Wallsend, Benton ASDA and Cramlington.
I'm sure there'll be more changes, but information on the public domain only confirms the above so far. More information here.
