High Peak reduce their 65 Buxton Sheffield to two round trips per day from next weekend - 22July. Stagecoach (with Derbyshire CC support) introduce new 65 Meadowhell Sheffield Buxton with buses around two hourly. See DCC bus timetable library for t/t’s.
Looks like Derbyshire CC have tendered for the times the reduced High Peak service doesn't run and Stagecoach have added in 2 commercial return workings at times which are close to the High Peak timings (but not directly duplicating High Peak services.) Any ENCTS holders in Tideswell will find the first High Peak service towards Sheffield is too early for free travel but they can board the slightly later Stagecoach service and get free travel.
