Mining of the early Northumberland Coalfield was taking shape. In 1794 a colliery was commenced within a mile of Cowpen, which at once brought a large increase of population and trade. "An Act of Parliament was obtained, and Cowpen Quay was erected... 1812 when Plessy Colliery was discontinued, a railroad was made to connect Cowpen Colliery with Blyth, as we have it at the present time, and instead of the coal being shipped at Cowpen Quay it was sent to Blyth."
