Can I check how many opportunities there are per hour on the 1/1A Hemel Hempstead to High Wycombe. bustimes.org would have me believe there are 2 buses per hour between 1/1A Hemel Hempstead and High Wycombe (the entire route). One 1A service and one 1 service per hour both operated by Carousel Buses. Interestingly both leaving within a short space of each other. However, when I download the timetable from carouselbuses.co.uk I am led to believe there is only one journey opportunity per hour consisting of the number 1 and that 1A services turn back short of Hemel Hempstead. (The 1A being operated by Arriva.) Which is correct?
