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.
This was the first American locomotive built for actual use on the first railroad on which steam was used as a motive power from the com-pletion of the road. The West Point was the second locomotive built in the United States for service on this same railroad, and its trial trip was on March 5, 1831.his was the first American locomotive built for actual use on the first railroad on which steam was used as a motive power from the com-pletion of the road.
