Using more modern, steam-operated machinery, the quarrying eventually burst through into the old Cogenhoe workings. Brand new equipment was used, including a standard gauge steam locomotive made by Andrew Barclay Sons & Co. which was kept in a brick engine shed on the side of the Hill, just west of Whiston village. In 1917, the works were leased out, and they then changed hands several times before closing in about 1922. The engine was transferred to the Hunsbury Hill Furnaces who bought out the company. The little engine shed has long since gone, but the old workings and railway tracks can still be picked out in the landscape.
