In 1981, production peaked at Roe, with 182 bodies built, the highest total since 1966 (the year when double-decks were finally allowed to be operated without a conductor, the first bus to do so, on the day of the law change, being a Great Yarmouth Roe-bodied Atlantean). The standard body was phased out in 1981, as the Fleetline had been discontinued and the Atlantean could not be sold after 1983 as it fell foul of noise-pollution laws. In 1981 the Park Royal coachworks were closed. The new body to take its place was for the new Leyland Olympian chassis and Roe produced 299 of these prior to closure. Most went to three fleets, West Yorkshire PTE and NBC subsidiaries Bristol Omnibus Company and London Country, with one batch to Strathclyde Passenger Transport Executive and a sole vehicle to the Scottish Arts Council, which was equipped as a travelling art gallery.
