I cant see that corridor warrants a 15 minute service. no need for a service X21 as its not busy on a sunday, and having a service 21 is better as it would stop at each stop to pick up potential passengers with out it being an express service, Monday to Saturday daytime express is more for getting passengers from one destination to another destination alot quicker.
Having the 21 on a sunday and not a X21 means the company are picking up passengers along the route and not leaving the passenger to use another bus company.
