Merthyr Tramroad from Penydarren to Abercynon in 1804, but proved unsatisfactory, partly because the engine was too heavy for the rails. It was only after the development of stronger rails made of rolled wrought iron in the 1820s that steam engine-hauled long-distance railways became feasible. Like the early wagonways, these were (indeed are) edge railways, where the wheels of the engine and wagons (or carriages) are flanged. Thus followed the Stockton and Darlington Railway, the Liverpool and Manchester Railway and many more. People were able to use railways to get to factory work and jobs much more effectively than previous options. - In 1829 George Stephenson and Robin Stephenson built a locomotive called “the rocket” See also George Stephenson Robert Stephenson Stockton and Darlington Railway Isambard Kingdom Brunel Stephenson's Rocket Charlotte Dundas James Watt George Washington References The Industrial Revolution 1760-1830, T.S.Ashton,Oxford University Press 1972 Industrial Revolution History of transport in the United Kingdom
