Trevithick Steamer

Richard Trevithick built a steamer which made its first run in Redruth in Cornwall on December 24th, 1801, and became known as the "Puffing Billy".

He built his London Steam Carriage in 1803. It was the first passenger-carrying powered vehicle, and was the product of years of research. It was preceded by the Cugnot steam tractor, which did not carry passengers.
