I can see that the 306, 308 and 311 have been coordinated to give a 20 minute frequency between Coast Road /Station Road and Haymarket.
Only change I'd suggest for Boxing Day schedules would be to change the last 311 to be a 306 (terminating at Billy Mill) but additionally serving Hadrian Park.
Yeah I know, it was instead of running duplicates on the 43/X10 corridor have both services running rather than not having the X21 running. They're pretty much different routes through out and it would be the next busiest service other than the X7.
