Directly next to the A1, and you can still see material remains of an early 19th century waggonway and colliery.

Between Chilton Moor and Great Lumley you can find this field - now part of a livery I think. This was once the site of the Lumley Eighth Pit. It was owned by the Earl of Durham and this was opened by the 1830s or 40s. It was ideally located on the Lambton Railway, which allowed easy transport to the huge staiths at Sunderland.

The pit predominantly provided household & industrial coal for factories and all sorts of dirty industry. Though relatively small, it was one of a string which lined this waggonway from Bournmoor all the way to Cocken Wood. This section was rope hauled, and before the A1 there was a substantial incline with two engines - one in the distance just passed the houses and another just south of Great Lumley.

This is the part of line which is very identifiable thanks to the field boundaries. That harsh curve is where waggons took on coal from the shaft and transported it northwards. In fact, see that circular earthwork? The shaft is in the undergrowth and very clearly identifiable.

The pit was out of use by the 1890s, so it's quite extraordinary to survive in this way.
