Following the end of the Second World War a new livery was introduced, starting with the company's six austerity Sunbeam trolleybuses. The red/brown livery which had been carried since the early days was replaced by a brighter green and cream livery. It was well received and the rest of the fleet followed. The first new vehicles to carry the livery were delivered in 1947. Route changes were proposed and first was an application to extend from the Adwick Road terminus in Mexborough to the newly built Windhill estate. It never happened and Windhill was not directly served until the coming of the motor bus route, itself short-lived (December 1948 to June 1953) as the route was unprofitable. The second application was to ease the traffic problems in the narrow streets of Conisbrough and in this respect a new link along Station Road to allow one-way working was proposed, which was in use by March 1948.
