A 21 may do this for example; Chester - Newcastle -Durham - Newcastle - Chester (driver changeover) Chester - Newcastle - Chester - Newcastle. It's strange, but if you do the maths at 15 minutes at 2 hours from Newcastle to Durham and back it comes to a PVR of 8, but as I say the shorts do a run then do a full turn going to Durham the next time, and the remainder of the branded vehicles as well as a few extras do those to make up a frequency of every 7/8 minutes.
Having reviewed the timetables when they were first revealed - the short 21s work stand-alone as do the Durham ones. The combined PVR is 17, split PVR 10 for Durham and PVR 7 for the Chester shorts.
