London Buses - Arriva in North London - Hybrid Double Deckers

Features Arriva London's HA, HV and LT classes of hybrid double deck bus. Newest is the HA - a London variant of Alexander Dennis' Enviro 400H MMC. The very pleasant driver I spoke to (who very kindly let me have a look around one) had nothing but praise for them. I have the feeling that, in a few years, these are going to be a very common sight in London.
