The first picture shows one of Konectbus brand new ADL Enviro200s working the 5B to Eaton. YX69KPF appears to be working a 'new' Eaton Park and Ride route - something I wasn't aware of !!
Dan's final photo, under the cover of (almost) darkness, shows a Charcoal Line bus operating a Blue Line service. Former First Great Yarmouth Volvo B9TL 36181 BF12KXU is on the 26 to Norwich Railway Station.
My thanks to Dan for the photos
