It represents the world's first steam powered locomotive used for transportation on rails.    

On February 21, 1804, Richard Trevithick's unnamed steam locomotive hauled a train with five loaded cars along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales.         

Richard Trevithick (1771 – 1833) was a British inventor and mining engineer from Cornwall, England. His most significant contributions were the development of the first high-pressure steam engine and the first full-scale working railroad steam locomotive.
