St Denys railway station serves the St Denys and Portswood suburbs of Southampton in Hampshire, England. It is 77chain10chain down the line from .
Built in 1865, the station is named after the surrounding area, which in turn is named after the Priory of St Denys, a major landmark in medieval Southampton.
The station is at the site of the junction between the South West Main Line and the West Coastway Line running between Southampton and Portsmouth. It is currently served mainly by South Western Railway, with additional services operated by Southern. There are four platforms; two on the main line and two on the branch line.
The original station was opened by the London and South Western Railway on 1 May 1861 and named Portswood after the small village to the west of the main line. Shortly after, to accommodate the Portsmouth branch line, a new station building was built 0.25miles to the south; the relocated station was opened on 5 March 1866. However to avoid confusion with Portsmouth, the station was renamed to St Denys on 1 January 1876.[1]
The station buildings themselves are fine examples of the Victorian Italianate classical style architecture introduced to the LSWR by William Tite. The original 1867 station building on platform 1 is Grade II listed, now privately owned and renamed Drummond House. Platforms 2 and 3 house the waiting room and ticket window, whilst the old station buildings on platform 4 house The Solent Model Railway Group,[2] a local organisation.
All services at St Denys are operated by South Western Railway.
