Engine Pond

Engine pond, built in 1825 for the Stockton and Darlington Railway, is a circular structure about 8 metres across, made with rubble sandstone walls. It features a small square recess on the west side and a long curved channel on the east side that extends towards the railway line. The pond, which still holds water as of 2023, is fed by a stream from the west.

This rare surviving stone structure on the northern section of the railway provided water for the boilers of the stationary steam engine that powered the Etherley Inclines. The engine house with its boiler was located just southeast of the pond. To the north of the pond, there is a depression marking the site of a second circular pond. The surrounding area, including this listed pond, is part of a Scheduled Monument known as ‘Stockton & Darlington Railway: Etherley Inclines, summit and upper sections’.
