Wincomblee Brick and Tile Works; the 1st edition OS mapping shows a brickfield and clay pit on the site. These works were possibly out of use by 1895, as they are not shown on the 2nd edition OS mapping.

A Gasometer. Not shown on the 2nd edition OS mapping, so was out of use by 1895.

A waggonway serving Jane Pit in Walker Colliery (HER 4200) sunk in 1790. The line ran north-east to staiths at Wincomblee via West Engine Pit. The line also extended south from Jane Pit, moving coal to Walker Ironworks, looping around the facility. The waggonway then ran from Jane Pit to West Engine Pit in Walker Colliery. Engine Pit was sunk 100 fathoms to the High Main Seam in 1766 (Turnbull 2009, 105), closely followed by the adjacent Anne Pit (HER 42007). A long branch was also extended to the north-west from the middle of this waggonway which served Delight and Gosforth pits (HER 4210).

Wincomblee Copperas Works. This is not shown on the 2nd edition OS mapping, so probably out of use by 1895.

A Powder Magazine. Not marked on the 2nd edition OS mapping, so probably out of use by 1895.

Jane Pit (Coal). Walker Colliery opened before 1765 and closed in 1920. The shaft was deepened in the 1800s and made into the upcast shaft for Walker Colliery with two furnaces, one at each level worked. Only safety lamps were allowed in the mine. Owners were Lambert & Co (1850s), N.G. Lambert & Co and then Walker Coal Company Ltd.

Walker Iron Works. Probably out of use by 1895, as not shown on the 2nd edition OS mapping {1}. In 1810, William Losh (of Alkali Works, SMR 4197) along with Thomas Wilson and Thomas Bell, opened an iron foundry and engineering works opposite the alkali works. The Walker Iron Works was the largest in the North of England and included the manufacture of rails for the first railways, steam engines for mills, collieries and ironworks, and iron boilers and ship plates. Towards the end of the 1800s rising costs of importing raw materials eventually led to the transfer of the Walker iron industry to Middlesbrough and the iron works closed in 1891 {2}. Had 2 furnaces before 1850 and 5 by September 1868, 2 were blast furnaces. Had 50 puddling furnaces.

Brickfield. Probably out of use by 1895, as it is not shown on the 2nd edition OS mapping.

Walker Alkali Works. This is not shown on the 2nd edition OS mapping, so these works were out of use by 1895 {1}. Coal mining led to the establishment of the chemical industry in Walker due to the salt springs in the King Pit. William Losh moved his alkali works from Scotswood to Walker to take advantage of this valuable natural resource and set up the Walker Alkali Works by the river. Here he manufactured sulphuric acid, copperas, caustic soda and dyes. The Walker Alkali Works built the first Walker West School for the children of their workers. The chemical industry moved to Teesside in the late 1800s, eventually becoming ICI {2}.

A Brickfield. This is not shown on the 2nd edition OS mapping, so was probably out of use by 1895.
