Stephenson's Rocket wins the Rainhill Trials.

Stephenson's Rocket is an early steam locomotive of 0-2-2 wheel arrangement. It was built for and won the Rainhill Trials of the Liverpool and Manchester Railway (L&MR), held in October 1829 to show that improved locomotives would be more efficient than stationary steam engines.

The Rainhill trials were a competition run from 6 to 14 October 1829, to test George Stephenson's argument that locomotives would have the best motive power for the nearly-completed Liverpool and Manchester Railway (L&MR). Ten locomotives were entered, of which five were able to compete, running along a 1 mile (1.6 km) length of level track at Rainhill, in Lancashire.
