Tunbridge Wells West DEMU Depot (formally known as Tunbridge Wells West Engine Shed) was a traction maintenance depot located at Tunbridge Wells, Kent, England. It was made to serve Tunbridge Wells West and it's connecting lines and is now the main depot and station of the Spa Valley Railway.
The depot originally opened in 1866 by the London, Brighton & South Coast Railway with two roads which could hold six locomotives south of the station. By 1891, the depot was replaced by a larger four road shed north of the station.
Following bomb damaged on 20 November 1940 during World War 2, the original slate roof of the shed was replaced with corrugated asbestos. From 1950, The depot would get the code of 75F.
In June 1965, The depot closed for steam engines. Instead, the depot would store Class 205 and other DEMUs as well as engineering trains until the later 1970s. In 1973 the depot would get it's new code of TW.
The depot closed 6 weeks after the final line between Tunbridge Wells West and Eridge closed in 1985.
In the 1990s, The Tunbridge Wells & Eridge Railway Preservation Society would get ownership of the depot. Half of the depot has been restored with the other half being turned into Tunbridge Wells West on the Spa Valley Railway
