This object is one of only a few stone milemarkers made for the 1825 Stockton and Darlington railway. The Stockton and Darlington railway was the first railway line in the world in 1825 to transport passengers. It ran for a distance of 26 miles from Darlington, down to the port of Stockton. The line was primarily used for the transportation of coal, but with an early steam driven locomotive, it pulled the first passengers in the world on a fixed track. The stone can only be one of a few surviving relics from this iconic line and marks a chapter in history that led to rail transport worldwide.
The object is made of local sandstone. It is about 15 inches tall above ground, 12 inches wide and 8 inches deep. It has a curved top. The simple lettering is carved into the face of the stone. The stone symbolises one aspect of the British Industrial Revolution, where a number of engineering ingredients came together in the form of steam locomotive power, passenger movement and an organised transport system.
