It is most remembered as the place where wrought iron rails were invented by John Birkinshaw in 1820, which triggered the railway age, with their first major use being in the Stockton and Darlington Railway opened in 1823, about 45 miles to the south. Blyth Dene, near Bedlington, was an idyllic location next to the River Blyth which had all the right ingredients for an ironworks at the time: there were modules of ironstone in the coal laden banks of the river, there was plenty of wood for the traditional approach of charcoal making, water for driving the hammers, and the port of Blyth was only two miles downriver for shipping of the products. At the time, a Shropshire man, Abraham Darby had started a revolution in ironmaking by using coke instead of charcoal. The Bedlington ironworks originally consisted of two elements - a mill in Bebside and a furnace at Bedlington Mill.
