Wagonway, marked was Old on the 1st edition OS mapping, so out of use by 1857. The course is unclear on OS mapping, but probably served Mill Pit (HER 2615). It may have been an early line of, or precursor to, the Oxclose Wagonway (HER 3028). Alan Williams suggests that it is the earliest surviving plan of Washington Estate from the 1750s, shows Broomy Waggon Way running to a staith on the north bank of the River Wear at Cox Green. It was a short line, serving coal pits in Robert Shafto’s land in the south-east part of the estate. A map of 1764 included with a lease from Robert Shafto and Sir Gilfrid Lawson granting mining rights in Oxclose to a partnership led by a Newark Hudson, shows that the waggonway was extended to serve coal pits in this new area. The partnership built a waggonway 14 yards wide with one main way and one bye way with a staith 60 yards long and 20 yards wide at Cox Green. Around the same time, Lawson and Shafto granted a wayleave to Lord Ravensworth, Mary Bowes and John, Earl of Bute (the ‘Grand Allies’) from their Mount Moor Colliery which connected with the existing waggonway but used a new staith on Shafto’s land to the west. A bridge was also built to cross the significant valley of the Oxclose Burn.

In 1801, a new waggonway was constructed by the Grand Allies from Urpeth Colliery joining with the existing Broomy Waggonway at Mount Moor and on to the River Wear. Again, this ran to a new staith, this time to the east of the early staith on land owned by Sir Henry Vane. By this time, the Waggonway had become known as the Old Washington Way to distinguish it from Rudston's new route (HER2610) opened in 1787.

Mill Pit, marked as an Old Coal Pit on the 1st edition OS mapping, so was probably out of use by 1857.

Washington Mill (Corn), which appears to be a windmill.

The OS 1st edition mapping shows an Old Machine, with an adjacent spoil heap. It could perhaps have been a winding engine at the head of a shaft or a static engine on an incline.

C Pit (Air Shaft), with a windlass. It is not clear from the 1st edition OS mapping to which mine this shaft belonged. It was probably Washington.

Lane Pit, marked as an Old Coal Pit on the 1st edition OS mapping, so was out of use by 1857. An adjacent building also shown may have been related to this site but this is unclear from the mapping.

Wagonway, marked as Old on the 1st edition OS mapping, so was out of use by 1857. Entire course is unclear, but SMR 2594 a possible pit may have been its northern terminus and it may have run south to the road from Usworth Place to Great Usworth. Williams suggests that he line led from pits within Usworth Main or Russell’s Main Colliery to the north west of Washington to staiths on the south bank of the River Tyne at Bill Quay. It was in use between 1787 and 1836, shown on both Gibson’s map of 1787 and Casson’s map of 1803 as well as on Watson 24/10.

Shaft, in the north east corner of Usworth Place park. Their function is unclear on the 1st edition OS mapping, but is marked as Old so was out of use by 1857.

Sand Pit.

A Wagonway , connecting Usworth Quarry (SMR 2604) and Usworth Colliery (SMR 2607) to the North Eastern Railway (SMR 2625).
