'Loud Pit was an early C18th coal pit just west of Annfield Plain. Coal was taken along this waggonway, down gradient to the north in waggons pulled along wooden rails by horses. Their route would cross the River Derwent and reach the River Tyne at Dunston for loading onto keel boats.

The pit was eventually taken over by Pontop and East Castle Collieries west of Annfield Plain with coal transported by railway on the North Eastern Railway (now closed).'- Andrew Curtis, geograph
