Readers might wish to consult David Fry's Danger Ahead! -- Historic Railway Accidents (UK website) [ GPL ]. The first self-propelling steam engine or steam locomotive made its outing on 13 February 1804 at the Pen-y-Darren ironworks. The machine was designed by Richard Trevithick. The engine was able to pull a load of 15 tons at a speed of about 5 mph. However, adhesion was a problem (iron wheels on iron rails = slipping).
It is fitting that the first person to devise a working steam engine would be a man named Hero. Sixteen hundred years after the ancient Greek scientist first made mention of the untapped power of steam, the technology would become the hero and the engine that drove the Industrial Revolution.
