I'm sure it means they will be half hourly combined but I don't know the area so you'll be able to tell me better.
Currently its this (using times as an example):
43: 00 and 30 mins past
44: 15 mins past
44A: 45 mins past
As you can see, two 43s per hour, 1 44 per hour and 1 44A per hour (with the 44A being a 44 before the service was introduced).
All services combine to give a total frequency of 15 minutes along the corridors that all 3 services serve. If you then remove the 43 from the list, the 44 and 44A then combine to give a 30 minute frequency (hourly for both services separately). The 43 would then be replaced with the X43 which is increased to every 30 minutes so the timings should be like this (again, just an example):
X43: 00 and 30 mins past
44: 15 mins past
44A: 45 mins past
Eventhough the X43 does not follow the 44/44A at all (on a section where it stops anyway), the 15 minute combined frequency from Stanley to Metrocentre is still there and Tanfield Lea will still have their 30 minute service to Metrocentre as the X43 does not currently stop at Tanfield Lea at present, it is just scheduled to run through. Of course, this depends on whether the 43 is being withdrawn...
I know what i am trying to say, i just don't know whether i am putting it into words which you all understand. Apologies if i'm not.
