Catch Me Who Can Catch Me Who Can Catch Me Who Can was the fourth and last steam railway locomotive created by the inventor and mining engineer Richard Trevithick. It was an evolution of three earlier locomotives which had been built for Coalbrookdale, Penydarren ironworks and Wylam colliery. Demonstration runs began in July 1808, and "Catch Me Who Can" was the first locomotive in the world to haul fare-paying passengers. "Catch Me Who Can" was constructed during 1808 by the engineers John Urpeth Rastrick and John Hazledine at their foundry in Bridgnorth, England. It was demonstrated to the public at Trevithick's "Steam Circus", a

However, it was not possible to regulate the force of the blows. It seems probable that the Scottish Engineer James Nasmyth (1808–1890) and his French counterpart François Bourdon (1797–1865) reinvented the steam hammer independently in 1839, both trying to solve the same problem of forging shafts and cranks for the increasingly large steam engines used in locomotives and paddle boats. In Nasmyth's 1883 "autobiography", written by Samuel Smiles, he described how the
