The trackway linked the colliery settlement of Arrowthwaite, south of Whitehaven Harbour, to the Saltom Pit.
Saltom Pit
Saltom Pit dates back to 1729 and was the first pit in England to delve under the sea and at that time was the deepest undersea mine anywhere - an enormous, though risky, undertaking. Truly innovative in mining technology, the reality of Saltom Pit was that men, women and children worked below the sea bed to extract coal, for more than 100 years.
