A Sunday service will be operating except on routes 18, 33 and 36. The 18 and 33 won’t change from their current two-hour frequency and the 36 will be on a Saturday timetable.

David Squire, managing director, said: “These changes apply just to the four day Easter weekend and we will be introducing a revised timetable beginning on 14 April.

“The routes for the key workers remain over the weekend but with so few passengers we have scaled back accordingly.”
