The Steam Horse was an early railway steam locomotive constructed by the Butterley Company in Derbyshire in 1813 by William Brunton (1777–1851). Also known as the Mechanical Traveller, it had a pair of mechanical legs, with feet that gripped the ground behind the engine to push it forwards along the rails at about three miles an hour.
