The southern terminus of this line as recorded here is where it left the county. Its northern terminus was at the Low Lambton and Blackfell Staiths, (HER numbers 3076 and 3061 respectively). In 1812 John Nesham invested in a new line with iron rails from his Newbottle pits to Sunderland where the wagons could be unloaded directly into the colliery ships. Prior to this a wooden waggonway was in use by 1704 between the Earl of Scarborough's pits at Lumley and staiths at Penshaw. When Nesham's business ran into difficulty the railway was sold to John George Lambton in 1822. The Lambton Railway evolved into one of the great private industrial railways of the 19th and 20th centuries. It passed to the NCB along with the former Lambton collieries in the 1940s. The line through Penshaw was remained in use until the final closure of the Lambton Railway, along with New Herrington Colliery (the 'New Pit') in 1985, which marked the end of coal mining in the vicinity of Penshaw.

Low Lambton Staiths. The northern terminus (with Blackfell Staiths) of the Lambton Railway (HER 3077). Recorded on Burleigh & Thompson's 1737 plan. Still functioning in the 1860s. Labelled disused by the late 19th century. Some signs are visible along the river front and the wagonway track has now become a footpath.

Cox Green Station, on the North Eastern Railway, Painshaw Branch (SMR 2659) {1}. Disused railway tracks lifted, although level crossing gates and platforms remain. Station building in use as house {2}.

Quarry, marked as Old on the 1st edition OS mapping, so was out of use by 1858.

Low Lambton Quarries.

Sandstone worked from glassworks-owned Low Lambton Quarries was taken to Coxgreen and Penshaw staiths. At Coxgreen the wagonways were tunnelled through the hillside to emerge at the riverside staiths. Today three stone-lined tunnel entrances are still visible, although obscured by undergrowth.

Coxgreen Quarries.

During the 18th century and first half of C19, Cox Green was an important focus for the transhipment of locally mined coal from land to river. A number of wagonways ran through the settlement and terminated at drops or staiths on the riverside. Shipbuilding yards developed on this point of the river Wear also. A shipyard is shown on the first edition OS map to the north of active sandstone quarries. Nichol's Sands run along the full length of the shipyard. The shipyards included a timber yard.
