The beginning of the end of the trolleybus system started in 1953 when an order was placed for ten Leyland Tiger Cub motor buses with Weymann 44-seat bodywork and front entrances, which arrived the following year. Three other changes took place around that time. To house miners who were moving into the area, particularly from Scotland, the National Coal Board built a new estate, known as "The Concrete Canyon" at Sandhill, Rawmarsh, and, to serve this, a new route between Parkgate and Kilnhurst was developed. This was then extended to the Woodman Inn, Swinton and subsequently to the Cresswell Arms, Swinton. Secondly, a new route was introduced running from Rotherham to the newly built Monkwood estate in Rawmarsh, which joined the main road at the top of Blythe Avenue.
