Walton Colliery is shown on this site in the position of Cap House Colliery. Cap House IS the mining museum and is in the position indicated. Walton is not/was not part of this group and was some miles to the East of Wakefield near the villages of Walton & Crofton. Walton was known as Sharlston West pre-nationalisation. If someone can tell me how, I'll move it to the correct position.
