Also then you need to plan drivers schedules to account for every service to have a driver on a 6-12hr shift.

And all the interworkings on morning services like the Q3's going onto the Orbit (well used too), or the 35A from easington Lane to Sunderland interworking with the 24. To the absolute nightmare scheduling of Deptfords Sunday timetables.

Like on a sunday the a 20 will do two early 24s etc.
