Tanfield Waggonway

The Tanfield Waggonway was built by the Grand Allies from about 1720 to transport coal more reliably & cheaply from inland collieries of County Durham, to the staiths on the River Tyne at Redheugh.The route and structures of the oldest section of the now preserved part of the line, between Sunniside and Causey, dates from 1725, and is thus the world's oldest railway still in operation.
