Further to my earlier post, I was in Tynemouth this morning, waiting for a 306 to take me into North Shields. At Queen Victoria's monument the yellow sign at what was the Newcastle-bound stop had been removed and put onto the stop opposite, but it was irrelevant there, as it only applied to the Newcastle stop. Another passenger was also waiting for the 306, so we both kept looking in both directions, to see if a bus turned up.
The 306 did turn up on time, having come along Percy Park Road, i.e. along the original route. This stop isn't shown on the map to which I referred above.
A complete shambles by both bus companies and Nexus!
