Arriva have confirmed they will be pulling out of Aylesbury and Wycombe in July. I understand that Carousel is to take over the bulk of the Wycombe network and Oxford Bus is to run the direct Oxford to Aylesbury service once again and renumber it to 280, which it used to be of course. Carousel has put a statement on their website which I've just read. Hemel Hempstead will run the X5, former 500,but that'll be the only Arriva route in the Buckinghamshire county town except for the Milton Keynes service.
