Just reading complaints about the 21 on the Quality Contracts page and I've left this comment on it, so I'm post it on here to.
The problem with the 21 is A.) The 7/8 Minutes Frequency and B.) The 21 which terminates at Chester le Street if that is running late then obviously there is going to be 2/3 coming together and also the swap over can cause even more lateness would also lead to 2/3 buses coming together.
So here is my suggestion.
21 Durham - Chester le Street - Gateshead - Newcastle - Every 10 Minutes
Then Re-Route the one as far Chester le Street and Re-Number it 21A, The route would then be.
21A Chester le Street - Birtley - Eighton Banks - Wrekenton - QE Hospital - Gateshead - Newcastle Pilgrim Street - Every 15 Minutes
Perhaps a possible extension to Langley Park would then displace the X25 also the 28 between Chester le Street and Newcastle. Which then lead to the 28 following the 28A route and also increasing the frequency to every 15 minutes along the current 28A route.
This would also free up some buses on the PVR for the X25
