Again the 33 in Newcastle is a Nexus contract so not a service number determined by GNE.

The update also states the 40A will be replaced by a 41, but the timetable shows a 41D.

I had thought these D suffixes for the Durham Cathedral bus were internal only, so not entirely sure why the timetable section of the website is showing them. It's a bit confusing though!

I reckon it will operate as the 42, like you say the cathedral buses don't run with a D-suffix on the destination, although it is shown on the timetable. Same with the Nexus 33 which shows as 33N. Agreed doesn't help confusion when the extra letters are shown on the timetable.
