Alan There was an Eden Main Colliery 12.5 miles from Darlington, which I think was connected to the original Stockton & Darlington Railway. This is clearly not the one you are looking for... I am not sure where Dean's Primrose colliery, which was owned by Heworth Coal Co. Ltd, was. Not very helpful, I'm afraid. But may be part of the jigsaw?
