The Chatham Main Line is a railway line in England that links London Victoria and Dover Priory / Ramsgate, travelling via Medway (of which the town of Chatham is part, hence the name).Services to Cannon Street follow the route as far as St Mary Cray Junction where they diverge onto the South Eastern Main Line near Chislehurst.Services to Charing Cross as well as some slow Cannon Street services run in parallel from Gillingham to Rochester, diverging once across the River Medway at Rochester Bridge Junction onto the North Kent Line via Gravesend and Dartford.A shuttle service operates on the Sheerness Line which starts at Sittingbourne.Heading away from Victoria, between Farningham Road and Longfield Stations, the line which was used by Eurostar trains running from Waterloo International towards Fawkham Junction to pick up High Speed 1 still exists but is no longer used.
