Boldon Station, on the North Eastern Railway, Pontop and South Shields Branch (SMR 2290). Marked as a Coal and Lime Depot on the 1st edition OS mapping, 1857 survey. May have been conveying lime from the quarries and kilns around Down Hill. Originally a passenger station, later a lime and coal depot. The goods yard and coal depot have been reconstruced at Beamish Museum.

This quarry is marked as ‘Old’ on the 1st edition Ordnance Survey plan, so was presumably out of use by 1857.

These limekilns appear to be the two shown on the 1st edition OS mapping of 1857, with a track linking them to a quarry (HER 2308). They are not shown on 2nd edition OS mapping, so were out of use by 1895.
These structures were added to the South Tyneside local list in 2023. The local list description reads:
'Despite being located within the perimeter of the golf course, the lime kilns are best viewed from the southern part of Boldon Cemetery. The lime kilns are situated adjacent to the 3rd green on the golf course, but appear to be largely inaccessible, in an area of well-established dense undergrowth.
Anecdotal evidence has suggested that there may be some ruins of outbuildings associated with the lime kilns, immediately to the south, although these would also be covered by undergrowth.
Records indicate that the lime kilns were built in the 19th century but were out of use by 1895. The lime kilns are listed in the Tyne & Wear Historic Environment Record (HER 2309) & would appear to be associated with a former adjacent quarry, located a little further to the south (HER 2308).'

This quarry is marked as ‘Old’ on the 1st edition Ordnance Survey plan, so was presumably out of use before 1857. The 1st edition Ordnance Survey planalso shows a track to limekilns (HER ref. 2309), suggesting that this was a limestone quarry, supplying those kilns. The quarry seems to have been reworked between 1855 and 1895 as the 2nd edition Ordnance Survey plan, where it is again marked as ‘Old’, shows that it had expanded during that period.

Robinson's Quarry is marked as ‘Old’ on the 2nd edition Ordnance Survey plan, so was presumably out of use by 1895.

A lime kiln shown on the Ordnance Survey first edition map on the east side of Down Hill is not shown on the Ordnance Survey second edition map, so was out of use by 1895 {1}. The three arched kiln of limestone rubble dating from the late 18th century or early 19th century is set into a steep escarpment, and more typical of the small kilns producing lime for agricultural purposes than any of the other surviving kilns in the county {3}.
The lime kiln was listed Grade II in 1985 with the following description:
'Limekiln. Late C18/early C19. Roughly squared limestone rubble with brick dressings. 3 entrances, in 3 flat sides, have elliptical brick arches. Built against a steep hillside to use the stone from Downhill Quarry.'

This quarry is marked as ‘Old’ on the 2nd edition Ordnance Survey plan, so was out of use by 1895.

Engine House on the North Eastern Railway, Pontop and South Shields Branch (HER ref. 2290). This may have been associated with the nearby Dam (HER ref. 2302). It is not shown on the 2nd edition Ordnance Survey plan, so was out of use by 1895.
