However, conservative railway owners are skeptical about the ability of steam locomotives. They suggested that tractors fixed beside the railway should use towing cables to pull trains. In order to make people fully believe in the performance of the train, Stephenson made a "rocket" locomotive with good performance. The excellent performance of this locomotive finally changed the attitude of skeptics, and the Liverpool-Manchester railway became the first railway line in the world that was completely transported by steam engines. It is recognized by the bicycle industry that 1839, an Englishman Macmillan invented the pedal bicycle.
