 The company's first attempt at rail-less operation was in 1910 when a Thornycroft charabanc, hired from the Musselburgh Tramways Company, was tried for a short period, operating between the Old Toll Bar at Mexborough and Denaby Main Colliery Village, and also from Mexborough to Wath via Manvers Main Colliery.Objections from Mexborough Council caused the withdrawal of the service.In 1912, the company turned its attention to "rail-less traction" and set a bill before Parliament to authorise five trolleybus routes.
