Arriva Midlands has acquired newer Alexander Dennis Enviro400 MMC doubledeckers from Arriva Southern Counties and 16 older Volvo B9TL/East Lancs Olympus double-deckers from Yorkshire with upgraded exhausts. In a three-way swap, older Wright Gemini-bodied Volvo B7TLs and B9TLs have headed south from Leicester, with 2008-built Enviro400s moved from Kent to Yorkshire.
