Stagecoach have published their route consultation on-line.
https://www.stagecoachbus.com/promos-and-offers/south-west/route-consultation

Although entitled ‘Exeter Edition,’ the routes mentioned go beyond the City, particularly into East Devon, parts of Mid Devon, Teignbridge and West Devon.

Details of how to respond are on Page 7 of the document.

Changes to the timetable for Route 2 and 39 between Exeter and Newton Abbot are suggested to improve reliability.

The proposals  include a New Route 7/7A operating hourly between Exeter, Kingsteignton and Newton Abbot extending to Totnes (7) hourly and Torquay (7A) in the peak periods. This proposal would replace Route 46 between Exeter and Torquay and Route X64 between Exeter and Totnes

This is a review of Stagecoach’s commercial commitments. Any impact on County Council-supported services will be discussed with the Council and no changes to County-supported services may go forward without the Council’s agreement.
