The third change, which took place on 27 September 1954, was the replacement of the trolleybuses from Rotherham to Kilnhurst via the Green Lane loop by motorbuses. Bus services expanded rapidly to serve new communities which were developing, and in 1960 the Company obtained the powers to cease running trolleybuses and to run motor bus services instead. The Manvers to Conisbrough High route was the first to go, on 1 January 1961, but the rest did not last much longer, and the final trolleybus service ran on 26 March 1961 on the Conisbrough Low to Rotherham route. The following day, four trolleybuses ran in procession to mark the passing of an era. The leading vehicle, No.29, had part of its roof removed to allow a brass band, the Rawmarsh Prize Band, to provide music for the occasion. The Leyland Atlantean buses ordered as replacements were the first double-deck vehicles in the fleet, and the economics of the move can be seen in that they had 72 seats, as opposed to the single deck trolleybuses with 32 seats. The Company had been the first private company to operate trolleybuses in Britain, and were also the last to do so.
