He was an early pioneer of steam-powered road and rail transport and developed of the first high-pressure steam engine. He built the first full-scale working railway steam locomotive in 1804 and Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales.
