The first full-scale working railway steam locomotive was built by Richard Trevithick in the United Kingdom and, on 21 February 1804, the world's first railway journey took place as Trevithick's unnamed steam locomotive hauled a train along the tramway from the Pen-y-Darren ironworks, near Martyr Tydfil to Abercynon in South Wales. Accompanied with Andrew Vivian, it ran with mixed success.

The design incorporated a number of important innovations that included using high-pressure steam which reduced the weight of the engine and increased its efficiency.

Trevithick visited the Newcastle area in 1804 and he had a ready audience of colliery owners and engineers. The visit was so successful that the colliery railways in north-east England became the leading centre for experimentation and development of the steam locomotive. Trevithick continued his own steam propulsion experiments through another trio of locomotives, concluding with the Catch Me Who Can in 1808.

Another well known early locomotive was Puffing Billy, built 1813-1814 by engineer William Hedley. It was intended to work on the Wylam Colliery near Newcastle upon Tyne. This locomotive is the oldest preserved, and is on static display in the Science Museum, London.

George Stephenson built the Locomotion for the Stockton and Darlington Railway, north-east England, which was the first public steam railway in the world. In 1829, he built The Rocket which was entered in and won the Rainhill Trials. This success led to Stephenson establishing his company as the pre-eminent builder of steam locomotives used on railways in the UK, US and much of Europe.
