(2 hours ago)Adrian wrote Anything every 10 minutes or more frequent, I don't think it matters. Anything beyond that, then I think having a clock face timetable is important. 

I don't want to plan my journey every time I leave the house, I'd prefer the convenience of knowing my bus is due X, Y and Z past the hour, and that connects with A, B or C C onwards to Newcastle.

Yeah no arguments on the 30 minutes and above, agreed a 25 minute service would be silly. 

But surely a 40/45 minute service which isn't clockwork is more important than an hourly service? 

Imo the extra service one it's this infrequent starts to counteract the clockface issues. The 56 in Durham for example to just pick one out which is kinda in the middle zone probably where 30 minutes is too much but hourly is really too little.
