Quarry in quartz-dolerite dykes.

The site is now Parkley Fisheries, a quiet trout fishery. Remains of the old quarry plant survive among the trees on the north side, including foundations and fragments of the crusher. The railway route has been lost to regrading and ploughing, while the depot at Kingscavil was redeveloped for housing around 2000.

In January 1924, Linlithgow District Roads Committee opened a roadstone quarry at Cauldimmery, on the whinstone ridge of Nancy’s Hill east of Linlithgow. By running their own quarry, the Council hoped to reduce the cost of road repairs.

A half-mile, 2-foot gauge railway linked the quarry to a new depot and stone bins near the Edinburgh road at Kingscavil. The £4,000 scheme, partly funded by the new road tax, relied on second-hand equipment. Rails came from Scottish Oil Ltd., and the railway was worked by a reconditioned Dorman petrol locomotive, formerly with the War Department. A Robey semi-diesel engine powered the stone-breaker and air compressor.

The quarry operated for over 20 years, but flooding eventually forced closure. From the late 1940s until the early 1970s it was used as a reservoir for the local water supply.
