A large number of major changes are taking place in North Derbyshire at the end of the month:

As already mentioned, the 65 (Buxton-Sheffield) - presently jointly operated by TM Travel and High Peak - will pass to High Peak, resulting in the withdrawal of the present late departure from Buxton (1900) but the addition of a later weekday departure from Sheffield (1915, presently last departure is 1730)
Hulleys will take over operation of the 66 from G&J Holmes. The service is reduced to operate between Baslow and Tidewell or Buxton (only two journeys a day operate to Buxton and 3 departures from Buxton). The 66A varation is also revised - the weekday journeys from Baslow at 1435 continues from Tidewell to Castleton while the weekday morning journey in the opposite direction starts from Castleton at 0845.
These two journeys replaces the once-a-day service 68 which sees the end of a Castleton to Buxton through bus.
