Central tried various types, of rear engined double deckers, but found that none were to their satisfaction, and double deckers declined as a proportion of the fleet. The Atlanteans were sold in 1969, and a prototype Bristol VRX, operated from 1966, was returned to the manufacturer when a batch of 20 Bristol VRTs arrived, also in 1969. The VRT was not popular in Scottish Bus Group fleets, and all were sold to the National Bus Company in exchange for late-model Lodekkas in the early 1970s. A batch of 35 Daimler Fleetlines was delivered in 1971, but these were exchanged for single deck Leyland Leopards from other SBG companies in 1975. However, Volvo Ailsa B55s (30 purchased in 1978-79) and Dennis Dominators (51 in 1978-83) eventually found favour. When Central inherited Scottish Omnibuses' Airdrie operations in 1985, the Fleetlines and Leyland Olympians based there were not wanted by Central and were retained by Eastern Scottish. However, the last double deckers purchased by Central were in fact 10 Leyland Olympians, delivered in 1986.
