I would create a simplified service with a new ticket
The new ticket would be called the X lines Plus ticket...
It works similar to a transfare ticket however create an X line service say Stops Stanley Sunniside Tanfield Lea Metrocentre Newcastle
only stopping at certain stops. make it express /direct/ quick
There is another service that is longer and stops at every stop and goes off into villages etc... but with the ticket it means that passengers can get off and get on the express bus and vice verser.
It would be ambitious and useful if feeder buses stopped at the stop until the express service arrived and "swapped passengers"
Next stop announcement and tracking could be tweaked to say the next slower service is 3 Minutes behind this bus and this bus will arrive at Stanley 11mins quicker than service X
