The largest quarry in the UK has a very large railhead. This collection shows the alteration from ex BR iron ore tipplers and hoppers being used, through 4 wheel hoppers to large fleets of bogie hoppers and both 4 wheel and bogie box opens. Visited on 8 occasions, when a visit to the main office would produce an indemnity form, hard hat and "get on with it"! They didn't have internal users, but a large variety of aggregate carriers.
