William Hedley
William Hedley (13 July 1779 – 9 January 1843〔(【引用サイトリンク】 title=William Hedley - Britannica Online Encyclopedia )〕) was born in Newburn, near Newcastle upon Tyne. He was one of the leading industrial engineers of the early 19th century, and was instrumental in several major innovations in early railway development. While working as a 'viewer' or manager at Wylam Colliery near Newcastle upon Tyne, he built the first practical steam locomotive which relied simply on the adhesion of iron wheels on iron rails.
==Early locomotives==
Before Hedley's time, such locomotives were far too heavy for the track that was then available. While most lines used cable haulage with stationary engines, various other schemes had been tried. William Chapman at the Butterley Company in 1812, attempted to use a steam engine which hauled itself along a cable, while, at the same company, Brunton had produced the even less successful "mechanical traveller", or Steam Horse.
However, in 1812, Matthew Murray and John Blenkinsop had produced the first twin cylinder steam locomotive, ''Salamanca'', for Middleton Colliery railway near Leeds, using a pinion engaging with teeth along the iron edge rails track (first rack railway). This had been the first steam locomotive railway to work successfully, but the system was complex and expensive.
