9/9A is going and being replaced by the hourly 150 which should give a much better service, both in terms of frequency and hours of operation, and also punctuality as we know the current solution has been problematic.
The F70/F77 diverting past the OU once a day in each direction will stay for the moment but will likely end in October as part of wider changes to those services at the Luton/Dunstable end of the route; the link from campus to Leighton Buzzard will continue to be provided by the 150.
Below is the new timetable and a link to the online timetable.
