In 1860 the directors of the London, Chatham and Dover Railway decided to purchase 75 acres (30 ha) of land, formerly part of the Long Hedge farm in Battersea, to establish their new locomotive works and motive power depot.
Thereafter the works was used for heavy repairs until 1911, when much of the equipment and machinery was transferred to Ashford, leaving only the capacity to undertake light repairs associated with the adjoining Stewarts Lane motive power depot.
After the creation of the Southern Railway in 1923, the nearby Battersea depot of the London, Brighton and South Coast Railway was closed and Stewarts Lane grew to become the largest steam motive power depot of the system.
Most of the buildings of Longhedge works were demolished in 1957 to make way for a new depot for servicing electric trains.
The site is now occupied by the Stewarts Lane Traction Maintenance Depot.
