Will it do the X21 any harm to stop at Harlow Green bridge and the Canon, might add 2 mins overall.Even headways on sections of route common to more than one service isn't something that Go North East seems to both about any longer - e.g. northbound 21 & X21 within a few minutes from Plawsworth (Black Horse in CLS gets 4 buses per hour, but only 2 mins between 21 & X21); 25 & 50 run at the same time between CLS and Waldridge Park (and the 34 is the same time once an hour, as is the 701).
On the chester to Durham section, have the 50 and X21 run at 15 mins each and additional X21s for the peak times probably would be enough. But who knows what the future will bring.
