They could all be retimed especially the X20. And the 8/78 leaving Stanley is about 5 mins apart. 
Aswell the X1 is so badly timed with the X10/X9 to Newcaslte, if you switch the times that they go to Peterlee & dalton park that will solve that.

The 35 and X20 are both half hourly services so how is the 20 left with the section on its own for 40 mins? the 20 runs every 15 mins so even if the X20 is retimed 5 mins later there is still a chance the 20 and X20 will run behind each other from park lane to the board inn and vice versa, the 35 serves sunderland royal hospital so offers different connections to the 20 so passengers will wait for the 35 if that is where they need to be, then you have all the stagecoach services running up ad down durham road too, there is plenty of choice for users to use up durham road so retiming a couple will make no difference at all to this busy corridor
