Just to clarify the Enviro400 situation, it seems the Arriva North West Facebook page were mistaken and actually referring to Streetlites not Enviro400s when confirming Birkenhead's order of six new buses. These are for the 487, a route which can't accommodate double deckers anyway. So, to confirm, it is 47 new Enviro400s for the North West which are starting delivery now, 35 for Green Lane (routes 12/13 and 15) and 12 for Speke (route 75). Birkenhead is thus due 6 of the 11.5 m Streetlites (route 487). Sorry for the earlier confusion over this - the Facebook post was really ambiguous.

The remaining Enviro400s are 6 to Sapphire spec for Southern Counties' Maidstone depot (route 101). This accounts for the full order of 165: 100 for the North West, 34 for Yorkshire, 9 for The Shires, 9 for Wales, 7 for the North East and as mentioned the 6 for Southern Counties.
