The first steam locomotive was built by Richard Trevithick; it first ran on 21 February 1804, although it was some years before steam locomotive design became economically practical. The first commercial use of a steam locomotive was Salamanca on the narrow gauge Middleton Railway in Leeds in 1812.
Britain was a major force in the development of the steam engine and steam locomotives. Although prototypes had previously been created, the first full scale steam locomotive was built in Britain by British engineer Richard Trevithick in 1804. Unfortunately his steam locomotive was not well received.In 1814, the first successful steam engine locomotive was built by the British Engineer George Stephenson called Bluecher, blÃ¼cher which could haul up to 30 tons of coal at 4mph going. uphillhe steam powered engine is the heart of the steam locomotive. In order to understand how the locomotive works, it is important to first understand how the steam engine operates. This involves water and fire, which is used to create heat.
