Have you found a map for the revised route 25 please? This appears to follow a different route through the Cambridge Biomedical Campus, and no longer goes through the Trumpington Clay Farm development.Stagecoach all seems to be updated, as one would expect.
Another feature of the revised route 25 is that it is now operated by busway vehicles from Fenstanton.
I can't remember the source, but I think that I've read that Whippet will be working their way upwards to what the Cambridge and Peterborough Combined Authority are saying, but need time to get the resources in place.Whippet Coaches all seems to be on their website and on BusTimes and all tracking. The timetables, as noted above, fall somewhat short of what Cambridgeshire said they would be.
