Article: Local train services operate in the central, southern and eastern sections of the city and are operated by South West Trains, with stations at Swaythling, St Denys, Millbrook, Redbridge, Bitterne, Sholing and Woolston. Plans were announced by Hampshire County Council in July 2009 for the introduction of tram-train running from Hythe (on what is now a freight-only line to Fawley) via Totton to Southampton Central Station and on to Fareham via St. Denys, and Swanwick. The proposal follows a failed plan to bring light rail to the Portsmouth and Gosport areas in 2005.
