Whippet are revising the timetables on all their routes from Monday 3rd March.
In all cases there are minor changes to (try to) improve punctuality. But there are also some more significant changes, as noted below.
18A, 66, X3. Additional buses will operate on Saturdays, thanks to funding from the Combined Authority.
X3. Peak time services starting or ending at Papworth Everard will also serve Hilton and Fenstanton.
More details, and links to the new timetables, are available from the Whippet website.
