The Shepperton branch line is a 6-mile-51-ch (10.7 km) railway branch line in Surrey and Greater London, England. It runs from its western terminus at Shepperton to a triangular junction with the Kingston loop line east of Fulwell. There are intermediate stations at Upper Halliford, Sunbury and Hampton. The branch also serves a dedicated station at Kempton Park racecourse. All six stations are managed by South Western Railway, which operates all passenger trains. Most services run between Shepperton and London Waterloo via Kingston, but during peak periods some run via Twickenham.
The line was constructed by the Thames Valley Railway company and opened in November 1864. It became part of the London and South Western Railway (LSWR) the following year. The LSWR was responsible for double tracking and electrifying the line using the 750 V DC third-rail system. The replacement of the signalling was completed in June 2019 and train movements have been controlled from Basingstoke rail operating centre since April 2021. The Shepperton branch line is proposed for incorporation into Crossrail 2.
