Brusselton Reservoir sits near the top of the historic Brusselton Incline, one of the original features of the Stockton and Darlington Railway opened in 1825.

The reservoir was built to supply water to the stationary steam engine that hauled wagons up the incline during the railway's early years of operation.

This section of the line, running between Witton Park and Shildon, fell out of regular use relatively quickly as the railway expanded and locomotive technology improved.

The site lies close to the River Gaunless and is accessible on foot, with walking routes connecting it to Shildon and the surrounding countryside of County Durham.

The broader Brusselton Incline area retains visible earthworks and historic railway cottages, making it a point of interest for those exploring the heritage landscape of this pioneering early railway.
